However, the last few frames indicate that the colder-than-normal region tends to be shrinking in size with warmer-than-normal water encircling it (shown in orange). This is part of the process that will likely result in ENSO-neutral conditions during the next several weeks and then El Nino (warmer-than-normal) conditions by the early summer across the tropical Pacific Ocean.

The sharpest gradient appears to be in the region off the North Carolina coastline where colder-than-normal water on the northwestern side (Labrador current) clashes with warmer-than-normal (Gulf stream) water on the southeastern side (circled region). Low pressure systems tend to favor movement along temperature gradient zones which, in this case, would suggest an east-to-northeast push from North Carolina to out over the western Atlantic rather than “hugging the coastline” farther to the north.

The GFS holds back the northern wave of energy (circled) area and has a better defined frontrunning system allowing for a deeper and more rapid intensification of the surface low when compared to the Euro.

Lake Erie is the shallowest of the Great Lakes and is about 95% ice covered and Lake Huron has the second highest ice concentration of 77%. Normally, Arctic air that pushes into the northeastern states moves here by crossing the Great Lakes in a northwest-to-southeast fashion and this results in some modification of the air mass. In this weekend’s scenario, the chances for modification will be limited as the Arctic blast will come from the north…directly discharged to us from the frozen tundra region of eastern Canada.

The original Mexican-made heavy plastic Faiosa-framed glasses were thrown yards away from the crash site and buried in the snow only to re-appear in the spring when the snow melted along with a watch of “The Big Bopper”. Though the glasses were handed in immediately to the Cerro Gordo County Sherriff’s office, they sat filed away for the next 21 years in a sealed manila envelope marked “rec’d April 7, 1959”. The glasses were eventually returned to Holly’s widow and can now be seen in the exhibit at the Buddy Holly Center in Lubbock, Texas.

One storm track which dominated during the first half of the winter was along a line from southwestern Canada to the NE US. These “clipper” low pressure system pushed along in the polar jet which dominated the early winter. A “Miller A” storm track is one that takes low pressure right up over or near the eastern seaboard. A third storm track known as a “Miller B” features an initial or primary low that heads to the Appalachians, weakens, and transfers its energy to a newly forming secondary low just off the east coast. This “Miller B” scenario is what we will be dealing with this weekend in the northeastern part of the country. https://images.squarespace-cdn.com/content/v1/56530521e4b0c307d59bbe97/d2b84e4d-1531-45b3-8567-f1018b455015/download.png Blog - *****Major winter storm to impact the DC-to-Philly-to-NYC corridor from later Saturday night into Monday…significant snow accumulations and serious icing…bitter cold to follow***** - Make it stand out While surface temperatures will remain below-freezing throughout this event, there can be a thin layer of air nosing into the upper atmosphere with slightly above-freezing temperatures and this can cause sleet to fall instead of snow.

One storm track which dominated during the first half of the winter was along a line from southwestern Canada to the NE US. These “clipper” low pressure system pushed along in the polar jet which dominated the early winter. A “Miller A” storm track is one that takes low pressure right up over or near the eastern seaboard. A third storm track known as a “Miller B” features an initial or primary low that heads to the Appalachians, weakens, and transfers its energy to a newly forming secondary low just off the east coast. This “Miller B” scenario is what we will be dealing with this weekend in the northeastern part of the country. https://images.squarespace-cdn.com/content/v1/56530521e4b0c307d59bbe97/a5ac0d10-80b4-4ac3-9253-8881ae13e0f6/download.png Blog - *****Major winter storm to impact a large part of the nation this weekend...significant snowfall in the Mid-Atlantic and some icing possible...bitter cold air sets the stage...bitter cold follows***** - Make it stand out While surface temperatures will remain below-freezing throughout this event, there can be a thin layer of air aloft with slightly above-freezing temperatures and this can cause sleet to fall; especially, across the southern Mid-Atlantic.

The disruption of the polar vortex can set off a chain events that ultimately help to unleash Arctic air masses from northern Canada into the US and, if history is any guide, that can result in some intense cold.

However, when a stratospheric warming event takes place, there is a disruption or weakening of the polar vortex, and the westerly (or called zonal) winds can drop to near 0. In fact, it appears the zonal (westerly) winds at 60 degrees N will drop to near 0 on two occasions in the near-term just a few days apart (indicated with arrows).

In the early stages of the winter season, an MJO that moves into “phases 7, 8 and 1” is often correlated with colder-than-normal weather conditions across much of the northern US.

The arrow on this temperature forecast map for late November points to an area of substantial warming in the stratosphere (10 millibar level) and this warming could shift to the North Pole region by early December.

The city’s official temperatures in 1936 were logged at the University of Chicago which was a little more than a mile from Lake Michigan. Temperatures at Midway Airport and other inland locations tell a much different story of the unprecedented heat than those reported at the official site.

In fact, this was reportedly the latest time for the first hurricane to develop in the Northern Hemisphere since 1993. The western Pacific Ocean has not had a single named system so far this season (that could change in a few days) and that may be the latest time ever for that to take place.

Following long-term trends, temperatures during these cold season months have been generally running at above-normal levels. And if long-term trends hold true for the summer (melting) season, then temperatures in June, July, and August should run at nearly normal levels which happens to be right around the 32 degree (F) mark. As long as temperatures remain close-to-normal during the summer (melting) season, there will likely be a limit to the amount of additional melting that can take place with respect to the Arctic sea ice.

This creates more atmospheric drag - or air friction - on low-orbiting objects, which slows them down and hastens their fall.

The impact on US temperatures in each of those six years during the subsequent month of April was quite dramatic. In fact, the average temperature in those six years for the month April was below-normal across virtually the entire nation (right plot).

The original Mexican-made heavy plastic Faiosa-framed glasses were thrown yards away from the crash site and buried in the snow only to re-appear in the spring when the snow melted along with a watch of “The Big Bopper”. Though the glasses were handed in immediately to the Cerro Gordo County Sherriff’s office, they sat filed away for the next 21 years in a sealed manila envelope marked “rec’d April 7, 1959”. The glasses were eventually returned to Holly’s widow and can now be seen in the exhibit at the Buddy Holly Center in Lubbock, Texas.

This initial system can have an influence on the path of the potential tropical storm while it is over the eastern Gulf of Mexico. The second feature will be a ridge of high pressure that will build across the eastern states (and actually can “surround” the tropical system, right forecast map). As such, there is a chance the forward motion of the tropical storm comes to a halt next week and this could lead to some very heavy rainfall amounts in certain areas.. Indeed, we could be dealing with this tropical system as late as at the end of next week somewhere farther north up along the eastern seaboard.

A “late in the game” turn to the NW is likely for Beryl, in my opinion, due to a repositioning of high pressure over the US to the western Atlantic. https://images.squarespace-cdn.com/content/v1/56530521e4b0c307d59bbe97/31413854-74e2-42b8-a57e-1bb2dbd459e8/Picture1.png Blog - 12:30 PM (Wed) | ***Hurricane Beryl pounds Jamaica...reaches Yucatan Peninsula on Friday...weekend turn to the NW puts Texas landfall in play*** - Make it stand out The eastward movement of high pressure now over the eastern US (left map) to the western Atlantic (right map) may open the door Hurricane Beryl to take a turn to the northwest from west-northwest. This turn to the northwest could very well put southern Texas on the table for a possible landfall of Beryl by late in the weekend or during the early part of next week.

Upwelling is a process that results in colder waters from underneath to rise up to the surface and this may very well be taking place right now under the center of Beryl over the Caribbean Sea…we’ll know more on any water temperature change over the next couple of days. A cooling at the surface would be less favorable for intensification of the trailing tropical system that is following close behind Beryl.

When the moon covers the Sun's bright face, the corona is definitely the main attraction.

Yellow curves indicate how much of the Sun is covered by the Moon outside the path of totality. The difference between a total solar eclipse and a partial one is literally the difference between night and day, so get yourself into the path of totality if you can. https://images.squarespace-cdn.com/content/v1/56530521e4b0c307d59bbe97/12356506-5cbe-4944-879b-3d8db672b770/Picture4.gif Blog - Saturday PM update: *A look at cloud cover prospects for solar eclipse Monday, April 8th* - Make it stand out This animated GIF shows the Moon’s shadow arcing across the Pacific, then traversing North America, and ending at sunset not far from Spain. The longest duration will be near Torreon, Mexico at 4 minutes and 27 seconds. The inner black circle, the umbra, is where the shadow is complete — a total eclipse of the Sun. The outer shadow circle, the penumbra, shows the extent of the partial eclipse. The partial eclipse will be slight near the outer circle and deep near the path of totality. https://images.squarespace-cdn.com/content/v1/56530521e4b0c307d59bbe97/fe300930-fac6-46b4-a511-14a43d4b0090/Picture5.png Blog - Saturday PM update: *A look at cloud cover prospects for solar eclipse Monday, April 8th* - Make it stand out Whatever it is, the way you tell your story online can make all the difference. https://images.squarespace-cdn.com/content/v1/56530521e4b0c307d59bbe97/6638f14c-eaae-4e9b-b4e3-f73ed7b9b1bd/Picture6.png Blog - Saturday PM update: *A look at cloud cover prospects for solar eclipse Monday, April 8th* - Make it stand out These are the times and durations of the eclipse at several points inside the path of the total solar eclipse. https://images.squarespace-cdn.com/content/v1/56530521e4b0c307d59bbe97/645facfe-f5a9-4517-b3e6-80e48623c968/Picture1.png Blog - Saturday PM update: *A look at cloud cover prospects for solar eclipse Monday, April 8th* - Make it stand out This map shows the 20-year (2000-2020) “median cloud fraction” in the month of April at approximately 1:30 pm local time as measured from NASA’s Aqua satellite.

When the moon covers the Sun's bright face, the corona is definitely the main attraction.

The original Mexican-made heavy plastic Faiosa-framed glasses were thrown yards away from the crash site and buried in the snow only to re-appear in the spring when the snow melted along with a watch of “The Big Bopper”. Though the glasses were handed in immediately to the Cerro Gordo County Sherriff’s office, they sat filed away for the next 21 years in a sealed manila envelope marked “rec’d April 7, 1959”. The glasses were eventually returned to Holly’s widow and can now be seen in the exhibit at the Buddy Holly Center in Lubbock, Texas.

The first wave began during late November and continued into mid-December and the second one in the early and middle portions of January. There is a lag of several weeks between the time the “burst” of stratospheric warming takes place and the ultimate impact on US temperature patterns.

Depending on its location or “phase”, it can provide important clues as to temperature and precipitation patterns that can develop in other parts of the world away from the tropics. During this time of year, a movement by the MJO into phases 8 and 1 usually results in colder-than-normal weather conditions for much of the central and eastern US. As we progress into the middle of February, the MJO is indeed predicted to rotate in a counter-clockwise fashion into these particular (cold) phases (as indicated by the blue circles (Day 15) and green circles (Day 20) in the above diagram).

Solar disturbances have long been known to disrupt communications, wreak havoc with geomagnetic systems, and to pose dangers for satellite operations. The Sun is represented as a yellow dot, the Earth by a green dot, and the two STEREO spacecraft by the red and blue dots. The top row represents the WSA-Enlil predicted solar wind density and the bottom row the predicted solar wind velocity.

This plot shows the trend of an index value known as the “multivariate ENSO” (MEI) which factors in such parameters as pressure, winds, and outgoing longwave radiation in addition to the more conventional sea surface temperature anomalies. The latest reading of the MEI (indicated by arrow) suggests this El Nino may not be nearly as impactful as several recent strong-to-super strong El Nino events.

The vertical line on the plot represents the “December/January/February” sea surface temperature anomaly values as depicted by numerous models in the “3.4” region of the tropical Pacific and the overall trend is for weakening as the winter season progresses.

The teleconnection index known as the Eastern Pacific Oscillation or EPO will drop sharply into “negative” territory next week (right plot) and this usually signals the formation of a strong ridge of high pressure in the upper part of the atmosphere from near Alaska to western Canada and that is exactly what is depicted in the 12Z GFS forecast map (left) by next Tuesday.

On this “in-between” day, very cold air surged into the Philly metro region on the backside of a strong coastal storm and several inches of early season snow accumulated in some suburban locations.

Low pressure along the Mid-Atlantic coastline not only generated some rainfall for Game 1, but it funneled in very chilly air from the north as well and the combination of the cold and wet conditions played a role in the overall sloppy performance.

Tropical moisture will flow into this intensifying system to the southeast of the low pressure center. Combine this expected tropical moisture with Atlantic moisture (onshore winds) and the result may be quite a widespread and soaking rain event for much of the eastern US.

First, it will contribute to an intensifying pressure gradient between the high to the north and the low to the south which will, in turn, lead to strengthening onshore winds. Second, this ridge will combine with additional ridging over the western Atlantic to influence the storm to push northward through the eastern states instead of taking an “out-to-sea” path.

Daily data include observations of maximum and minimum temperature, precipitation amount, snowfall amount, and snow depth; monthly data consist of monthly-averaged maximum, minimum, and mean temperature and total monthly precipitation. Most of these stations are U.S. Cooperative Observing Network stations located generally in rural locations, while some are National Weather Service First-Order stations that are often located in more urbanized environments. Through the end of July, 53% of the USHCN stations reached 95 degrees (F) which is the lowest on record for the time of year and much lower than the peak of 93% that occurred in 1931.

Temperatures at Midway Airport and other inland locations tell a much different story of the unprecedented heat than those reported at the official site.

As long as temperatures remain nearly normal in the summer months, there will likely be a limit as to the melting of Arctic sea ice. Indeed, with nearly normal summertime temperatures in recent years, Arctic sea ice has been rather resilient in terms of both extent and volume.

The general temperature pattern in this six-year time period (as well as in the current year of 2023) has featured nearly normal temperatures in the summer (melting) season and well above-normal values in the nine months before and after. In fact, this kind of annual temperature pattern has persisted since the beginning of the 21st Century. Temperature data is estimated from the average of 00Z and 12Z analysis for all model grid points. The ERA40 reanalysis data from the ECMWF has been applied to calculate daily mean temperatures for the period of 1958-2002. Data plots courtesy Danish Meteorological Institute (DMI).

It was a typical hurricane season with an average number of named storms, a slightly above-average number of hurricanes, a slightly below-average number of major hurricanes. The state of Florida was hit the hardest in the US during last year’s tropical season with direct hits just six weeks apart. https://images.squarespace-cdn.com/content/v1/56530521e4b0c307d59bbe97/ce5d168f-ba9f-4529-aa02-ca8af8e1b8bf/iri_aprl.PNG Blog - *2023 Tropical and Summer Outlook* - Make it stand out The graph shows forecasts made by dynamical and statistical models for SST in the Nino 3.4 region for nine overlapping 3-month periods. Note that the expected skills of the models, based on historical performance, are not equal to one another. The skills also generally decrease as the lead time increases. Thirdly, forecasts made at some times of the year generally have higher skill than forecasts made at other times of the year--namely, they are better when made between June and December than when they are made between February and May. Differences among the forecasts of the models reflect both differences in model design, and actual uncertainty in the forecast of the possible future SST scenario.

Yellow curves indicate how much of the Sun is covered by the Moon outside the path of totality. The difference between a total solar eclipse and a partial one is literally the difference between night and day, so get yourself into the path of totality if you can.

The longest duration will be near Torreon, Mexico at 4 minutes and 27 seconds. The inner black circle, the umbra, is where the shadow is complete — a total eclipse of the Sun. The outer shadow circle, the penumbra, shows the extent of the partial eclipse. The partial eclipse will be slight near the outer circle and deep near the path of totality. https://images.squarespace-cdn.com/content/v1/56530521e4b0c307d59bbe97/764d3f9a-e8b4-4a2b-b704-3c4c5f09b7aa/1.PNG Blog - 7:15 AM | *The next great total solar eclipse on US soil is now just under a year away...Monday, April 8th, 2024* - Make it stand out Whatever it is, the way you tell your story online can make all the difference. https://images.squarespace-cdn.com/content/v1/56530521e4b0c307d59bbe97/9dc0ebb2-440f-48c1-afff-bf8231c3a992/2.PNG Blog - 7:15 AM | *The next great total solar eclipse on US soil is now just under a year away...Monday, April 8th, 2024* - Make it stand out These are the times and durations of the eclipse at several points inside the path of the total solar eclipse. https://images.squarespace-cdn.com/content/v1/56530521e4b0c307d59bbe97/07b0b2a1-d66f-430e-a6f5-b1800e6dc56d/c75c7fff-f7a6-4f54-8107-03fcf901cf10_1140x641.jpg Blog - 7:15 AM | *The next great total solar eclipse on US soil is now just under a year away...Monday, April 8th, 2024* - Make it stand out The moon covers the sun during a total solar eclipse in Piedra del Aguila, Argentina, Monday, Dec. 14, 2020.

Depending on its phase in a particular time of year, this teleconnection index can give clues as to upcoming temperatures patterns in the US. In this case, Phase 8 and Phase 1 tend to correlate with colder-than-normal conditions across much of the central and eastern US and that is forecasted by this particular computer forecast model (JMA) in coming days.

Specifically, the Euro forecast from this vantage point (and that is still several days away) depicts the following: 1) high-latitude blocking over Canada, 2) a deep trough in the eastern US, 3) high pressure ridge axis through the interior western US, and finally 4) an upper-level low near the “50/50” (latitude/longitude) benchmark …all of which are usually favorable for snow in at least parts of the Mid-Atlantic/NE US.

The original Mexican-made heavy plastic Faiosa-framed glasses were thrown yards away from the crash site and buried in the snow only to re-appear in the spring when the snow melted along with a watch of “The Big Bopper”. Though the glasses were handed in immediately to the Cerro Gordo County Sherriff’s office, they sat filed away for the next 21 years in a sealed manila envelope marked “rec’d April 7, 1959”. The glasses were eventually returned to Holly’s widow and can now be seen in the exhibit at the Buddy Holly Center in Lubbock, Texas.

A neutral or positive PNA index value this time of year generally correlates with ridging of high pressure over western US and Canada which, in turn, aids in the influx of cold Canadian air masses into the central and eastern US and the formation/intensification of an eastern US upper-level trough of low pressure.

Plot courtesy NOAA/CPC https://images.squarespace-cdn.com/content/v1/56530521e4b0c307d59bbe97/50ce967e-0fcb-4349-9c1f-5f91546673ae/6_La_Nina_patterns.png Blog - *2022-2023 Winter Outlook* - Make it stand out La Nina will likely be the dominant player again this winter season in the equatorial Pacific Ocean with colder-than-normal sea surface temperatures. Typically, this type of oceanic sea surface temperature pattern leads to an active polar northern jet across Canada and much of the northern US and colder-than-normal conditions from Alaska to the Northern Plains. In addition, La Nina winters are often warmer and drier than normal in much of the southern US from California-to-Florida with a usually persistent ridge in the southeastern states. https://images.squarespace-cdn.com/content/v1/56530521e4b0c307d59bbe97/d14f55d2-2fb2-49a5-8d17-4beac7781461/7_analog_years_temp_anomalies.png Blog - *2022-2023 Winter Outlook* - Make it stand out Whatever it is, the way you tell your story online can make all the difference. https://images.squarespace-cdn.com/content/v1/56530521e4b0c307d59bbe97/c6068432-7ad0-41c7-b25b-ef260fe34e62/8_analog_years_precip_anomalies.png Blog - *2022-2023 Winter Outlook* - Make it stand out US temperature (top) and precipitation (bottom) anomalies averaged together during the December-to-March time period for the three selected analog years (i.e., using the third winter in a “back-to-back-to-back” La Nina event).

Every day galactic cosmic rays from distant supernova explosions pass through the Solar System. When they hit the top of Earth's atmosphere, they create a secondary spray of radiation, which we measure using sensors onboard our balloons. Measurements since the onset of solar cycle 25 show a 15% reduction in the atmosphere high over California.

Every day galactic cosmic rays from distant supernova explosions pass through the Solar System. When they hit the top of Earth's atmosphere, they create a secondary spray of radiation, which we measure using sensors onboard our balloons. Measurements since the onset of solar cycle 25 show a 15% reduction in the atmosphere high over California.

While the Atlantic Basin experienced above-normal ACE, the Pacific Ocean more than offset this with far less activity compared to normal; especially, when considering the number of “major” hurricanes.

The original Mexican-made heavy plastic Faiosa-framed glasses were thrown yards away from the crash site and buried in the snow only to re-appear in the spring when the snow melted along with a watch of “The Big Bopper”. Though the glasses were handed in immediately to the Cerro Gordo County Sherriff’s office, they sat filed away for the next 21 years in a sealed manila envelope marked “rec’d April 7, 1959”. The glasses were eventually returned to Holly’s widow and can now be seen in the exhibit at the Buddy Holly Center in Lubbock, Texas.

The highlighted text appears to say “obstructions to visibility at this (scribbled)” and then what appears to be the word “terrified”. The obstruction to visibility at this time could have been “smoke”. The weather observer on this day was PFC Sherman Levine of the US Air Corps and he died during the attack, likely a few minutes after completing the last observation on this small slip of paper.

The annual tornado trends chart is a result of the following methodology applied to the SPC observed tornado dataset by Harold Brooks, NSSL and Greg Carbin, NOAA/SPC. Details: A simple linear regression equation is fit to the 1954-2007 annual tornado totals. This equation is then used to compute the delta, or difference, between the original/observed annual tornado total and the smoothed, or "adjusted" annual total represented by the point on the linear trend line for that year. https://images.squarespace-cdn.com/content/v1/56530521e4b0c307d59bbe97/2e1666bd-60b9-404f-8dec-e6c7b6300afb/image_thumb-202.png Blog - 12:00 PM | *Tropical cyclone activity below-normal in 2021 across the Northern Hemisphere…US tornadic activity also below-normal this year though there were outbreaks in unusual places* - Make it stand out According to NOAA’s Storm Prediction Center (SPC), the last recorded EF-5 tornado - the most violent classification level - was in the year 2013. https://arcfieldweather.com/blog/2021/11/16/700-am-another-chilly-day-in-store-but-with-much-less-wind-than-monday monthly 0.5 2021-11-16 https://arcfieldweather.com/blog/2021/11/16/700-am-not-as-windy-today-but-still-on-the-chilly-side-of-normal monthly 0.5 2021-11-16 https://arcfieldweather.com/blog/2021/11/16/700-am-still-on-the-chilly-side-but-with-much-less-wind-today-compared-to-yesterday monthly 0.5 2021-11-16 https://arcfieldweather.com/blog/2021/11/15/1200-pm-a-look-ahead-at-thanksgiving-weeka-potential-colder-and-stormy-pattern-and-a-quick-start-to-winter monthly 0.5 2021-11-16 https://images.squarespace-cdn.com/content/v1/56530521e4b0c307d59bbe97/338763b9-a90b-475b-a448-964d77f44993/eps.jfif Blog - 12:00 PM | ***A look ahead to Thanksgiving week…a potential colder and stormy pattern with a quick start to winter*** - Make it stand out The upper air pattern could evolve into one next week that features high-latitude blocking, an upper low over the eastern US and a popping ridge near the US/Canadian west coasts.

Water temperatures in the western Atlantic drop off pretty sharply from the Gulf Stream region to the southern New England coastline. This chill down in the water off the New England coastline can result in a weakening of the system in the hours before the potential landfall late Sunday.

The original Mexican-made heavy plastic Faiosa-framed glasses were thrown yards away from the crash site and buried in the snow only to re-appear in the spring when the snow melted along with a watch of “The Big Bopper”. Though the glasses were handed in immediately to the Cerro Gordo County Sherriff’s office, they sat filed away for the next 21 years in a sealed manila envelope marked “rec’d April 7, 1959”. The glasses were eventually returned to Holly’s widow and can now be seen in the exhibit at the Buddy Holly Center in Lubbock, Texas.

There are now thought to be as many as 79 moons of Jupiter with Europa being about the same size as Earth’s moon. https://arcfieldweather.com/blog/2020/12/17/700-am-snow-winds-down-this-morning-as-first-major-winter-storm-pulls-awaywindy-and-cold-remains-in-its-wake monthly 0.5 2020-12-17 https://arcfieldweather.com/blog/2020/12/17/700-am-windy-and-cold-in-the-wake-of-the-storm monthly 0.5 2020-12-17 https://arcfieldweather.com/blog/2020/12/17/700-am-windy-and-cold-in-the-wake-of-the-storm-1 monthly 0.5 2020-12-18 https://arcfieldweather.com/blog/2020/12/16/700-am-a-chilly-day-with-occasional-rain monthly 0.5 2020-12-16 https://arcfieldweather.com/blog/2020/12/16/700-am-showers-and-thunderstorms-possible-late-today-as-cold-front-arrives monthly 0.5 2020-12-16 https://arcfieldweather.com/blog/2020/12/16/1030-am-wed-high-impact-storm-for-the-mid-atlanticne-us-sleet-to-become-a-big-player-in-the-dc-to-philly-corridorprimarily-a-snow-event-for-upstate-pa-interior-upstate-nj-ny-new-england monthly 0.5 2020-12-17 https://images.squarespace-cdn.com/content/v1/56530521e4b0c307d59bbe97/1608131518907-FLHPTGTFWLBR9KEFJLH0/precip_types_NAM-3km.PNG Blog - 10:30 AM (Wed) | *****High impact storm for the Mid-Atl./NE US…sleet to become a big player in DC-to-Philly corridor…primarily a snow event for upstate PA, interior upstate NJ, NY, New England***** This major winter storm will result in a variety of precipitation types across the Mid-Atlantic/Northeast US.

In January 1610, Italian astronomer Galileo Galilei discovered four of Jupiter's moons — now called Io, Europa, Ganymede and Callisto. There are now thought to be as many as 79 moons of Jupiter with Europa being about the same size as Earth’s moon. https://arcfieldweather.com/blog/2020/12/10/700-am-nice-weekend-shaping-up-for-central-florida monthly 0.5 2020-12-10 https://arcfieldweather.com/blog/2020/12/10/700-am-an-unsettled-weekend-shaping-up-for-northern-alabama monthly 0.5 2020-12-10 https://arcfieldweather.com/blog/2020/12/10/700-am-high-pressure-takes-control-and-well-have-a-warming-trend-into-the-weekend-1 monthly 0.5 2020-12-10 https://arcfieldweather.com/blog/2020/12/10/700-am-high-pressure-takes-control-and-well-have-a-warming-trend-into-the-weekend-2 monthly 0.5 2020-12-10 https://arcfieldweather.com/blog/2020/12/10/700-am-high-pressure-takes-control-and-well-have-a-warming-trend-into-the-weekend monthly 0.5 2020-12-10 https://arcfieldweather.com/blog/2020/12/9/1030-am-snow-showers-are-closing-in-on-the-i-95-corridorsmall-accumulations-are-possible-in-some-spots-with-slick-spots-on-the-roadways monthly 0.5 2020-12-09 https://images.squarespace-cdn.com/content/v1/56530521e4b0c307d59bbe97/1607527566211-U5YRE8SM1TPRQI438S7X/Capture.PNG Blog - 10:30 AM (Wednesday) | ***Snow showers are closing in on parts of the I-95 corridor…small accumulations in some areas with quickly developing slick spots possible on roadways*** Snow showers are fairly widespread at this hour across central and northeastern PA and are pushing to the south and east.

While the North Atlantic has featured an extremely high number of tropical storms this season and its ACE is above normal, the Pacific Ocean has been quiet in terms of overall tropical activity and its ACE is well below-normal (compared to the climatological average of the 1981-2010 base period). In addition, the ACE for the Northern Hemisphere is well below-normal (boxed in region) as the Pacific Ocean easily outweighs the North Atlantic in overall influence.

While the North Atlantic has features an extremely high number of tropical storms this season, the ACE value is not too far from normal. The Pacific Ocean has been running at well below-normal in terms of ACE and this has contributed greatly to a below-normal ACE value for the Northern Hemisphere as a whole (boxed in region).

A kind of “milky haze” can be seen surrounding the tropical system which is related to Sahara Desert dry air that has been an inhibiting factor for intensification in recent days. The circulation center should become better defined in coming days, however, as more favorable environmental conditions develop (i.e., less dry air) and likely lead to intensification. Another tropical wave can be seen trailing the first one in the eastern Atlantic (lower, right).

AIM is located high above the clouds, taking pictures as it orbits over the poles. The colors — from dark blue to light blue and bright white — indicate the clouds’ albedo, which refers to the amount of light that a surface reflects compared to the total sunlight that falls upon it. Surfaces that have a high albedo are bright and reflect a lot of light and those that don’t reflect much light have a low albedo and appear dark.

According to the latest data from neutron counters at the University of Oulu’s cosmic ray station in Finland, cosmic rays are near an all-time high (upper, right) since measurements began in the 1960’s (i.e., within one percentage point when using the space age averages as a point of comparison).

Evidence for this rise comes from a campaign of almost weekly high-altitude balloon launches sponsored by spaceweather.com. Since March 2015, there has been a ~22% increase in X-rays and gamma-rays over central California where hundreds of balloons have been launched in this long-term effort. https://arcfieldweather.com/blog/2020/5/20/700-am-still-on-the-breezy-and-cool-side-here-as-high-pressure-sits-to-our-north monthly 0.5 2020-05-20 https://arcfieldweather.com/blog/2020/5/20/700-am-summer-like-pattern-sets-up-by-the-weekend monthly 0.5 2020-05-20 https://arcfieldweather.com/blog/2020/5/20/700-am-still-on-the-breezy-and-cool-side-as-high-pressure-to-our-north-remains-in-control monthly 0.5 2020-05-20 https://arcfieldweather.com/blog/2020/5/20/700-am-still-on-the-breezy-and-cool-side-with-high-pressure-to-our-north-still-in-control monthly 0.5 2020-05-20 https://arcfieldweather.com/blog/2020/5/20/700-am-looks-like-generally-a-warm-and-dry-day-across-florida monthly 0.5 2020-05-20 https://arcfieldweather.com/blog/2020/5/19/700-am-high-pressure-to-the-north-keeps-us-cool-and-breezy-2 monthly 0.5 2020-05-19 https://arcfieldweather.com/blog/2020/5/19/700-am-not-as-warm-today-but-still-somewhat-unsettled-with-a-chance-of-showers-and-storms monthly 0.5 2020-05-19 https://arcfieldweather.com/blog/2020/5/19/700-am-very-warm-today-with-a-continued-threat-of-showers-and-thunderstorms monthly 0.5 2020-05-19 https://arcfieldweather.com/blog/2020/5/19/700-am-high-pressure-to-the-north-keeps-us-cool-and-breezy-1 monthly 0.5 2020-05-19 https://arcfieldweather.com/blog/2020/5/19/700-am-high-pressure-to-the-north-keeps-us-cool-and-breezy monthly 0.5 2020-05-19 https://arcfieldweather.com/blog/2020/5/18/700-am-an-unsettled-week-with-plenty-of-opportunities-for-showers-and-storms monthly 0.5 2020-05-18 https://arcfieldweather.com/blog/2020/5/18/700-am-chance-for-strong-to-severe-thunderstorm-activity-today monthly 0.5 2020-05-18 https://arcfieldweather.com/blog/2020/5/18/700-am-in-general-a-cool-first-half-of-the-week-with-plenty-of-clouds-around monthly 0.5 2020-05-18 https://arcfieldweather.com/blog/2020/5/18/700-am-in-general-a-cool-and-damp-first-half-of-the-week-with-plenty-of-clouds-around monthly 0.5 2020-05-18 https://arcfieldweather.com/blog/2020/5/18/700-am-in-general-a-cool-first-half-of-the-week-with-plenty-of-clouds monthly 0.5 2020-05-18 https://arcfieldweather.com/blog/2020/5/15/700-am-low-pressure-to-intensify-next-24-48-hours-over-the-sw-atlantican-impact-here-later-today-and-tonight-as-it-begins-to-move-to-the-northeast monthly 0.5 2020-05-15 https://arcfieldweather.com/blog/2020/5/15/700-am-low-to-mid-80s-today-as-summer-like-air-reaches-the-mid-atlanticpossible-strong-coastal-storm-by-the-middle-of-next-week monthly 0.5 2020-05-15 https://arcfieldweather.com/blog/2020/5/15/700-am-summer-like-warmth-through-the-weekend monthly 0.5 2020-05-15 https://arcfieldweather.com/blog/2020/5/15/700-am-80-degrees-today-as-summer-like-air-reaches-the-mid-atlanticpossible-strong-coastal-storm-by-the-middle-of-next-week monthly 0.5 2020-05-15 https://arcfieldweather.com/blog/2020/5/15/700-am-first-80-degree-day-of-the-seasonpossible-strong-coastal-storm-by-the-middle-of-next-week monthly 0.5 2020-05-15 https://arcfieldweather.com/blog/2020/5/14/120-pm-potential-for-the-first-official-tropical-system-of-the-2020-atlantic-basin-tropical-seasonits-possible-contribution-to-a-coastal-storm-by-the-middle-of-next-week monthly 0.5 2020-05-18 https://images.squarespace-cdn.com/content/v1/56530521e4b0c307d59bbe97/1589476387971-0OY689BSEYJ0H7USFL13/CODNEXLAB-GOES-East-regional-gulf-natcolorfire-17_06Z-20200514_map_-10-1n-10-100.gif Blog - 1:20 PM (Thursday) | *Potential for the first “official” tropical system of the 2020 Atlantic Basin tropical season* Low pressure is forming over the Florida Straits and it may become the first “official” tropical system of the 2020 Atlantic Basin tropical season.

When this index is in “negative” territory for an extended period of time this time of year as shown in the latest forecast, it oftens indicates favorable conditions for colder-than-normal air masses to drop from Canada into the central and eastern US. Another teleconnection index known as the Madden-Julian Oscillation (MJO) also supports the idea of a colder-than-normal pattern setting up for the central and eastern US (see video discussion).

Note that the expected skills of the models, based on historical performance, are not equal to one another. The skills also generally decrease as the lead time increases. Thirdly, forecasts made at some times of the year generally have higher skill than forecasts made at other times of the year--namely, they are better when made between June and December than when they are made between February and May. Differences among the forecasts of the models reflect both differences in model design, and actual uncertainty in the forecast of the possible future SST scenario. https://images.squarespace-cdn.com/content/v1/56530521e4b0c307d59bbe97/1582731897272-X6CUTKZNW8B74URDVG8O/table.png Blog - 7:15 AM | *La Nina may form in the equatorial Pacific Ocean later this year and, if so, it could have wide-ranging ramifications* DESCRIPTION: Warm (red) and cold (blue) periods back to 1990 based on a threshold of +/- 0.5°C for the Oceanic Niño Index (ONI) [3 month running mean of ERSST.v5 SST anomalies in the “Niño 3.4” region (50°N-50°S, 120°-170°W)], based on centered 30-year base periods updated every 5 years. https://images.squarespace-cdn.com/content/v1/56530521e4b0c307d59bbe97/1583178021626-AVCRBQJAN98R5PX8X8HM/uah.png.jpg Blog - 7:15 AM | *La Nina may form in the equatorial Pacific Ocean later this year and, if so, it could have wide-ranging ramifications* University of Alabama-Huntsville (UAH) satellite-based temperature data of the global lower atmosphere from 1979 to the present.

The original Mexican-made heavy plastic Faiosa-framed glasses were thrown yards away from the crash site and buried in the snow only to re-appear in the spring when the snow melted along with a watch of “The Big Bopper”. Though the glasses were handed in immediately to the Cerro Gordo County Sherriff’s office, they sat filed away for the next 21 years in a sealed manila envelope marked “rec’d April 7, 1959”. The glasses were eventually returned to Holly’s widow and can now be seen in the exhibit at the Buddy Holly Center in Lubbock, Texas.

The unusual weather was not confined to eastern North America as there was strange weather recorded all over the world. The cold and rainy summer in Switzerland even inspired Mary Wollstonecraft Shelley to begin the novel “Frankenstein”.

On Dec. 5th and 6th they surged within a percentage point of the Space Age record, according to data from neutron counters at the University of Oulu's Cosmic Ray Station in Finland.

This finding comes from a campaign of almost weekly high-altitude balloon launches conducted by the students of Earth to Sky Calculus. Since March 2015, there has been a ~22% increase in X-rays and gamma-rays over central California, where the students have launched hundreds of balloons. The grey points in the graph are Earth to Sky balloon data. Overlaid on that time series is a record of neutron monitor data from the Sodankyla Geophysical Observatory in Oulu, Finland. The correlation between the two data sets is impressive, especially considering their wide geographic separation and differing methodologies. Neutron monitors have long been considered a “gold standard” for monitoring cosmic rays on Earth. This shows that our student-built balloons are gathering data of similar quality. https://images.squarespace-cdn.com/content/v1/56530521e4b0c307d59bbe97/1576162478335-GP2RHK24DGPUCFHQ5MAM/Sunspot_Numbers.png Blog - 10:00 AM | *Deep solar minimum on the verge of an historic milestone* 400 years of sunspot observations; courtesy Wikipedia https://images.squarespace-cdn.com/content/v1/56530521e4b0c307d59bbe97/1576162668368-ZJ3NC9IHIZ4QCTMPNOJ4/1.png Blog - 10:00 AM | *Deep solar minimum on the verge of an historic milestone* Temperature recordings at the Greenland Ranch weather station in Death Valley, California during the intense heat wave of July 1913.

The highlighted text appears to say “obstructions to visibility at this (scribbled)” and then what appears to be the word “terrified”. The obstruction to visibility at this time could have been “smoke”. The weather observer on this day was PFC Sherman Levine of the US Air Corps and he died during the attack, likely a few minutes after completing the last observation on this small slip of paper.

The obstruction to visibility at this time could have been “smoke”.

Encounters occurring after 1950 are highlighted as the modern era, which signifies the time that scientific studies began to focus on the physics and chemistry of comets, rather than just qualitative descriptions of their behavior. Note that the distance from Earth is not necessarily an indicator of brightness. Of the comets on the modern-era list, only #4 IRAS-Araki-Alcock and #5 252P/LINEAR (and hopefully #10 46P/Wirtanen) reached naked eye brightness, while many of the others were not detected because they were too faint (#8 323P/SOHO).

Encounters occurring after 1950 are highlighted as the modern era, which signifies the time that scientific studies began to focus on the physics and chemistry of comets, rather than just qualitative descriptions of their behavior. Note that the distance from Earth is not necessarily an indicator of brightness. Of the comets on the modern-era list, only #4 IRAS-Araki-Alcock and #5 252P/LINEAR (and hopefully #10 46P/Wirtanen) reached naked eye brightness, while many of the others were not detected because they were too faint (#8 323P/SOHO).

It has similar applications to the Mid-Level Water Vapor band but can add further clarity to jet-streaks and shortwave features embedded within large scale atmospheric flow patterns. It also has been proven to be useful in identifying/tracking volcanic plumes. Additionally, in combination with the other two water vapor bands, this data can be ingested by numerical weather models to improve forecasts by better approximating initial conditions of the atmosphere at large scales.   https://arcfieldweather.com/blog/2018/7/26/700-am-weekend-looks-pretty-decentmore-wet-weather-next-week monthly 0.5 2018-07-26 https://arcfieldweather.com/blog/2018/7/26/700-am-upper-level-trough-kicks-out-of-the-southeast-usnew-upper-level-trough-forms-over-the-midwest-early-next-week monthly 0.5 2018-07-26 https://arcfieldweather.com/blog/2018/7/26/700-am-generally-rain-free-today-in-the-tennessee-valley-as-upper-level-trough-kicks-out-to-the-northeast-of-here monthly 0.5 2018-07-26 https://arcfieldweather.com/blog/2018/7/26/700-am-weekend-looks-pretty-decentmore-wet-weather-next-week-1 monthly 0.5 2018-07-26 https://arcfieldweather.com/blog/2018/7/26/700-am-weekend-looks-pretty-decentmore-wet-weather-next-week-2 monthly 0.5 2018-07-26 https://arcfieldweather.com/blog/2018/7/25/1230-pm-coastal-storm-to-enhance-rainfall-for-mid-atlanticnortheast-us-this-afternoon-and-tonight monthly 0.5 2018-07-25 https://images.squarespace-cdn.com/content/v1/56530521e4b0c307d59bbe97/1532536124231-HBSZLGBDSQJUBFYXJ01L/hrrr_ref_frzn_neus_fh1-18+%281%29.gif Blog - 12:30 PM | ***Coastal storm to enhance rainfall later this afternoon and tonight in the Mid-Atlantic/Northeast US*** High-resolution (HRRR) computer forecast model for the next 18 hours in 1-hr increments featuring the formation of a coastal low over New Jersey; courtesy NOAA, tropicaltidbits.com https://images.squarespace-cdn.com/content/v1/56530521e4b0c307d59bbe97/1532536247523-DAL0IW3K11KWMKK162M0/CODNEXLAB-2km-VA_WV-rad-ani24-201807251605-100-100-raw.gif Blog - 12:30 PM | ***Coastal storm to enhance rainfall later this afternoon and tonight in the Mid-Atlantic/Northeast US*** Latest radar loop shows large swath of intense rainfall riding northward along the Mid-Atlantic coastline.

This particular channel is especially good at showing areas where cooler dense plumes of plasma (filaments and prominences) are located above the visible surface of the sun. Many of these features either can't be seen or appear as dark lines in the other channels. The bright areas show places where the plasma has a high density.

Berkowski captured the image — the first to accurately represent the solar corona — in Königsberg in what was then the Roman Empire, now Kaliningrad in Russia. He used a small refracting telescope with a diameter of 2.4 inches (6.1 centimeters) and exposed the daguerreotype plate for 84 seconds, beginning soon after the sun was completely obscured, according to a study published in 2005 in the journal Acta Historica Astronomiae.

In fact, this is the 7th day in a row with no sunspots on the sun and the 51st day of the year. The sun will likely feature even more frequent blank days over the next several months as we continue towards the next solar minimum. The current solar cycle (#24) has been the weakest in more than a century since cycle 10 peaked in 1906.

The reverse side is coarser resolution because we are less concerned with that part of the world. By enhancing the resolution only over a part of the earth, we are able to economically get to ultra-high resolution simulations of important areas, or on a potentially-dangerous storm, anywhere around the globe. The colors represent the grid spacing lengths, and the grid is partially outlined in black.

When the Earth’s shadow crosses the moon during an eclipse, the sunlight is turned off, and some parts of the lunar surface cool faster than others. The areas that hang on to their warmth longer than their surroundings appear as “hot” spots. Fine moondust areas on the surface tend to cool quite rapidly whereas fresh blocky craters can hang on to their warmth for a longer period of time and appear as “hot” spots.

Carrying two satellites on behalf of the U.S. military, the rocket lifted off at 8:56 p.m. EDT on Aug. 12th (0056 GMT on Aug. 13th). When multiple satellites are deployed from a single rocket, the rocket sometimes spins to help the payloads go in different directions. That could account for the spiral shape of the exhaust.” https://images.squarespace-cdn.com/content/v1/56530521e4b0c307d59bbe97/1750186489037-9TFTC6XMUG20KHJNA8RY/image-asset.jpeg Image of the week gallery - The Perfect Tornado Severe weather threats have continued into the late spring across much of the nation as we have had numerous clashes between colder-than-normal air masses and warm, humid air.

Stromboli is one of the most active volcanoes in the world – renowned for its regular, but normally minor, eruptions that send lava oozing from vents inside its crater. It has been active for thousands of years. The minor eruptions which are often visible from the island and surrounding sea have given rise to its nickname of the “Lighthouse of the Mediterranean.” Credit Image: Francesca Utano, volcanodiscovery.com https://images.squarespace-cdn.com/content/v1/56530521e4b0c307d59bbe97/1715629355374-XVWQO185N9MERWU5LPPT/image-asset.jpeg Image of the week gallery - Auroras in strange places A very large sunspot region unleashed a series of coronal mass ejections (CMEs) that impacted the Earth's atmosphere on Friday night and Saturday (May 10th/11th, 2024).

To illustrate their similarity, spaceweather.com has added Carrington's famous sketch (to scale) to a NASA photo of today's sun. Sprawling almost 200,000 km from end to end, AR3664 is 15 times wider than Earth. On September 1st, 1859, a ferocious solar storm took place that impacted much of the planet. This ferocious solar storm is now known as the “Carrington Event”, named after the British astronomer, Richard Carrington, who witnessed the largest solar flare from his own private observatory which caused a major coronal mass ejection (CME) to travel directly toward Earth. https://images.squarespace-cdn.com/content/v1/56530521e4b0c307d59bbe97/1713371135212-6G501GFQH2WLKAUR4WWP/image-asset.jpeg Image of the week gallery - Volcanic eruption in Indonesia (April 17th, 2024) Hundreds of people in Indonesia had to be evacuated from their homes in the North Sulawesi province as the Ruang volcano continues its days-long eruption.

In addition, snowpack in the Sierra Nevada Mountains of eastern California is still in evidence as we head into the second half of July. This is despite the fact that hot weather has encompassed the Golden State in recent days. (Note -there are a few clouds over the snowpack region). This past winter season of 2022-2023 brought record snowfall amounts to the Sierra Nevada Mountains.

These wavy clouds are usually below 7,000 feet and associated with a thick layer of turbulence. Asperitas is a cloud formation first popularized and proposed as a type of cloud in 2009 by Gavin Pretor-Pinney of the Cloud Appreciation Society. Added to the International Cloud Atlas as a supplementary feature in March 2017, it is the first cloud formation added since “cirrus intortus” in 1951.

These storms have filled California's Lake Oroville with more than 526 billion gallons of water—nearly half of its capacity—between 12/21 and 3/8, bringing it up 168 feet. https://images.squarespace-cdn.com/content/v1/56530521e4b0c307d59bbe97/1674492134426-D7CWZ03LRBETIK6IT59V/image-asset.png Image of the week gallery - Lenticular Cloud This photograph of an unusual lenticular cloud took place near Bursa, Turkey on January 20th, 2023. Bursa — where the cloud was seen — is about 50 miles south of Istanbul, across the Sea of Marmara. What made the cloud in Bursa especially aesthetically pleasing was the time of day it formed — shortly before sunrise. Its altitude, probably around 10,000 to 20,000 feet, allowed it to catch sunlight and be illuminated before the sun actually poked over the horizon and bathed the city in amber warmth. Lenticular clouds (Altocumulus lenticularis, meaning “shaped like a lentil” in Latin) mostly develop among the crests and valleys of mountainous terrain. They are associated with waves in the atmosphere that form when moist air flow is forced up, over and partway down a mountaintop.

A shelf cloud will usually be associated with a solid line of storms and can form at the leading edge. The wind will come first with rain following behind it. It may appear to rotate on a horizontal axis. Wall clouds will rotate on a vertical axis, sometimes strongly. If you see a shelf cloud coming your way, it probably means you are about to get hit by a strong thunderstorm.

Throughout the month of June, Mercury, Venus, Mars, Jupiter and Saturn have lined up from left to right, in their orbital order from the sun, before dawn in the southeastern sky. Early Friday (June 24), the moon joined the planet parade in an awesome sight captured by astrophotographer Wright Dobbs, a meteorologist for the U.S. National Weather Service in Tallahassee, Florida. While the show did hit its peak on June 24th, there's still time available to see the planets in alignment, along with the moon. The moon moved through a planetary "meet and greet" in the predawn sky, passing Saturn on June 18, Jupiter on June 21 and Mars on June 22. The moon will continue its tour with a pass-by of Venus on June 26, and then end its tour with Mercury on June 27.

At the end of the week, he found he couldn't stop. "I kept going and photographed the sun for 365 days in a row," says Mukherjee. "This image is a blend of all the pictures I took," he says. "It shows every sunspot that crossed the solar disk from Dec. 25, 2020, to Dec. 31, 2021. Only 6 days are missing due to complete cloud cover." The composite image reveals two things: First, all of the sunspots are concentrated in two bands--one north and one south of the sun's equator. Second, the south seems busier than the north. The southern band is wider and there are more sunspots. Solar physicists have long known that the two hemispheres of the sun don't always operate in sync. The great Solar Cycle 19 of the 1960s, for instance, was mostly northern, an assymetry which persisted for more than 15 years. More recently, Solar Cycle 24 had a strong southern peak in the year 2014. Other cycles have been a seesaw mix of north and south with only razor-thin margins separating the two. How will Solar Cycle 25 shape up? So far it is speaking to us with a southern accent. https://images.squarespace-cdn.com/content/v1/56530521e4b0c307d59bbe97/1646072376192-YDKE4B56RG4PAGTZ1T2F/image-asset.png Image of the week gallery - Train of Starlink satellites This photograph of Starlink satellites operated by SpaceX was taken on Friday, February 25th from London, England by an amateur astronomer.

This “partial” eclipse will actually be very close to “total” as nearly 97% of the moon’s surface will be shrouded in the Earth’s shadow at the peak. The eclipse will last about three and a half hours – the longest such eclipse in nearly 600 hours. What makes this eclipse so long? The Moon is near apogee, the farthest point in its orbit around Earth. Because the Moon moves slowly at apogee, it takes longer to cross Earth's shadow. According to Sky & Telescope, this will be the longest partial lunar eclipse since Feb. 18, 1440 — and we won't get a longer one until Feb. 8, 2669. https://images.squarespace-cdn.com/content/v1/56530521e4b0c307d59bbe97/1636041456282-5TBMHHM73BLWISXQVC84/image-asset.jpeg Image of the week gallery - Northern Lights from Space As solar cycle 25 gets farther along, the number of sunspots is climbing and the northern lights are becoming more frequent.

They positioned themselves south of Andrews (Texas), got out their gear (Olbinski using an extreme wide-angle lens, as the storm would soon literally be on top of them), and witnessed powerful updrafts as the weather evolved before their eyes. Updrafts—warm, ascending air currents within storm clouds—cause evaporated moisture to rise to cooler altitudes, where it then matures into heavier rain and hail, before plunging down to the earth amid colder airflows. Under the right conditions, warm air currents surrounding the cell can help this process, causing the whole thunderstorm—sometimes miles wide—to collapse in an instant in a massive downward rush of wind, rain, and hail, producing what’s known as a “microburst.” Distinct from tornadoes, microbursts can be just as destructive with winds sometimes reaching 150 miles per hour. The wind, rain, and hail hit the ground with such force, it has nowhere to go except outwards and can cause devastation in all directions, toppling trees and structures. The supercell on this particular day was about to go microburst ballistic—a “microburst machine,” as Olbinski called it. They witnessed a single, massive column of torrential downpour, at first, with the magnificent colors of a Texas sunset adding to the spectacle. From the sky fell three more pillars of wind and hail, producing a “quadruple microburst”.

Etna (Italy) erupts again Mount Etna, or Etna, is an active stratovolcano on the east coast of Sicily, Italy, in the Metropolitan City of Catania, between the cities of Messina and Catania. It lies above the convergent plate margin between the African Plate and the Eurasian Plate. Etna has had multiple eruptions during the past few weeks and the one on the morning of March 12, 2021 produced a plume of ash and steam that reached approximately 10 kilometers in altitude. The ash and steam column drifted east, causing heavy lapilli and ash fall in places on the eastern sector of the volcano including Milo, Giarre and others. This latest eruption was particularly powerful and rather long-lasting, marking the 12th such event in a row.

It has been nearly 800 years since the two giant gas planets have appeared so close together AND have been so easy to see. Often, the glare of the sun makes their convergence difficult or even impossible to see, but this year is very special because the conjunction happens comfortably away from the sun. The last time these two gas giants have appeared this close together was in the year 1623 during Galileo’s times, but the sun’s glare that year very likely obscured the pair of planets to sky watchers on Earth. The last time the two giant gas planets appeared so close together AND were so easy to see was during medieval times in March of the year 1226. While Jupiter and Saturn appear quite close together to us in the sunset sky, they are actually about 450 million miles apart from each other. In this photograph taken in Florida through an 8-inch telescope, the largest moons of both planets are visible (photo courtesy spaceweather.com).

Air layers of different densities just above the surface of the water severely distorted the image of the sun. Warm air, strong temperature gradients, and at least one temperature inversion sliced the image of the setting sun into multiple shape-shifting layers. Briefly, the sun assumed the form of a mushroom cloud, followed by a sequence of other shapes including a rectangle. Giant sunspot AR2778 (note the black streak, lower left, in the image above) was stretched, compressed, and ultimately obliterated.

Fall 2020 was no exception. Aided by a period of chilly weather, fall foliage was peaking in the region’s forests in late September. On September 22, 2020, the Visible Infrared Imaging Radiometer Suite (VIIRS) on NOAA-20 acquired this image of the area around Lake Superior, which is rich with aspen, birch, maple, basswood, and other deciduous hardwood trees. In autumn, the leaves on deciduous trees change colors as they lose chlorophyll, the molecule that plants use to synthesize food. Chlorophyll makes plants appear green because it absorbs red and blue sunlight as it strikes leaf surfaces. It is not a stable compound and plants have to continuously synthesize it to keep their leaves green—a process that requires ample sunlight and warm temperatures. When temperatures drop and days shorten, levels of chlorophyll drop as well. As green chlorophyll fades, other leaf pigments—carotenoids and anthocyanins—show off their colors. Carotenoids absorb blue-green and blue light, appearing yellow; anthocyanins absorb blue, blue-green, and green light, appearing red. As explained by the U.S. Forest Service (https://www.fs.usda.gov/visit/fall-colors/science-of-fall-colors), certain species of trees produce certain colors. Oaks generally turn red, brown, or russet; aspen and yellow-poplar turn golden. Maples differ by species. Red maple turns brilliant scarlet; sugar maple, orange-red; and black maple, yellow. Leaves of some trees, such as elms, simply become brown.

"It was a triple comet," says Karl Battams of the Naval Research Lab in Washington DC, who made this animation using coronagraph images from the Solar and Heliospheric Observatory (SOHO). "The two main components are easy to spot, with the third, a very faint, diffuse fragment following alongside the leading piece," he says. SOHO finds comets all the time. Most are Kreutz sungrazers, fragments of a giant comet that broke up more than 1000 years ago. Since the observatory was launched in 1995, SOHO has discovered more than 3000 members of the Kreutz family dive-bombing the sun. And that's what makes this comet unusual. "It is not a member of the Kreutz family," says Battams. "Its orbit doesn't match. We're not yet sure where it came from." The triple comet is now receding from the sun, fading rapidly from view. There's a slim chance that large ground-based telescopes might be able to track it. If so, they could find clues to its make-up and origin. https://images.squarespace-cdn.com/content/v1/56530521e4b0c307d59bbe97/1595529066270-RVHPYK7TMM5ADKSC13B5/image-asset.jpeg Image of the week gallery - Comet NEOWISE near its closest approach to Earth Comet NEOWISE will reach perigee or its closest distance to Earth at about 64.3 million miles on Thursday, July 23rd. This photograph was taken on July 18th. The comet has dimmed some in recent days and is generally visible to the naked eye from dark sites only with the best of atmospheric conditions (i.e., low humidity, no clouds). This comet has certainly not been a disappointment for skywatchers in terms of terms of overall viewing - unlike two comets earlier in the year, ATLAS and SWAN, which disintegrated upon their approach to the sun. Comet NEOWISE won’t be back this way for another 6800 years because of its extremely long, elliptical orbit.

Then there was Comet SWAN in May which also disintegrated. And now we have a third comet named NEOWISE and this one is coming through and could be visible until mid-August. In recent days, this comet has been visible shortly before sunrise, but now, it has become an evening object as well and will actually be visible at both ends of the day for the rest of this week.

The dry, dusty desert air mass over the tropical Atlantic has a few clusters of thunderstorms on its perimeter to the south and northwest. The air mass that originated in northern Africa several days ago is an inhibiting factor for tropical activity in the Atlantic Basin and it could lead to brilliant (colorful) sunsets in parts of the US early next week.

Halos can have many forms, ranging from colored or white rings to arcs and spots in the sky. Many of these appear near the sun or moon, but others can occur elsewhere and even in the opposite part of the sky. Among the best known halo types are the circular halo (properly called the 22° halo), light pillars, and sun dogs, but many others occur; some are fairly common while others are (extremely) rare. This photograph of a circular halo around the sun was taken in East Norriton, Pennsylvania on the morning of Wednesday, June 17th. High clouds pushed into this region on this day ahead of a slowly (northward) moving upper-level low pressure system that has been spinning over the Carolinas in recent days. A contrail can also be seen in the lower, left portion of the photograph.

NASA’s Aeronomy of Ice in the Mesosphere (AIM) spacecraft first spotted wisps of noctilucent or “night-shining” clouds over the Arctic region in late May. In recent days, however, these clouds have been seen in the continental US (Washington, Minnesota) and the growing chill aloft suggests this summer could be as good or maybe even better than last summer when records were set for low-latitude sightings. In fact, temperatures in recent days in the mesosphere layer of the atmosphere have be the lowest since 2007 when NASA’s AIM spacecraft began monitoring noctilucent clouds. Research studies have shown that these clouds tend to be more prevalent during solar minimums and we have been in the midst of one since last year.

This brightness is hundreds of times brighter than astronomers predicted when it discovered the comet several months ago. While it is still too dim to see with the unaided eye, it is becoming an increasingly easy target for backyard telescopes. The comet is expected to become much brighter by the time it sweeps by the sun closer than Mercury during late May, it could even rival Venus in the evening sky.

These clouds look like breaking ocean waves, with the rolling eddies seen at the top of the cloud layers. The eddies are usually evenly spaced, making the clouds easily identifiable. Kelvin-Helmholtz clouds are named for Lord Kelvin and Hermann von Helmholtz, who studied the physics of the instability that leads to this type of cloud formation. A Kelvin-Helmholtz instability forms where there’s a velocity difference across the interface between two fluids: for example, wind blowing over water. You’ll often see the characteristic wave structure in this type of cloud when two different layers of air in our atmosphere are moving at different speeds. The upper layers of air are moving at higher speeds and will often scoop the top of the cloud layer into these wave-like rolling structures. The clouds often form on windy days, when there’s a difference in densities of the air, for example, during a temperature inversion. They’re often good indicators of atmospheric instability and the presence of turbulence for aircraft. https://images.squarespace-cdn.com/content/v1/56530521e4b0c307d59bbe97/1582919214752-ZVR195HL67PMCHR0ZO7Y/image-asset.jpeg Image of the week gallery - Small-scale snow event in Kansas A narrow band of heavy snow blanketed parts of Kansas on Tuesday, February 25, 2020. Up to 13 inches of snow was reported in this band that was only 7 to 15 miles wide. The snowband developed over western Nebraska and northern Kansas on Monday night and continued into Tuesday. Once skies cleared, satellite imagery showed the pencil-thin band from space. It could also be seen from flights over Kansas. The skinny nature of this single band is similar to the width of lake-effect snowbands in the Great Lakes, but unusual for the middle of the heartland. https://images.squarespace-cdn.com/content/v1/56530521e4b0c307d59bbe97/1581705894529-V0RC99T4HS96CM32MHF0/image-asset.png Image of the week gallery - Powerful Jet Streak over the North Atlantic On Feb. 8, 2020, British Airways Flight 112 (BA 112) rocketed from New York to London in a mere 4 hours 56 minutes, at one point traveling faster than 825 mph. It did this by surfing the jet stream. A couple of very strong storms in the North Atlantic in recent days have been associated with powerful jet streaks aloft. Another one of these powerful jet streaks will develop on Friday night and persist into Saturday, February 15th in the same region if this prediction comes true by the latest run of NOAA’s GFS computer forecast model. https://images.squarespace-cdn.com/content/v1/56530521e4b0c307d59bbe97/1581535200524-27RRHNHYRGKDDYSB306H/image-asset.png Image of the week gallery - North Atlantic Storm Rapidly intensifying low pressure clipping southern Newfoundland on Wednesday, February 12 is forecast to deepen 46 millibars over the next 24 hours into the central Atlantic.

Lava gushed from the volcano and forced villagers to flee and resulted in a shut-down of Manila’s international airport. Clouds of ash blew more than 60 miles to the north reaching the capital of Manila. Taal underwent frequent eruptions in the mid-1960’s and then again in 1977 (both solar minimum time periods). In 2006, 2008, 2010 and 2011, the volcano periodically trembled with earthquakes and occasionally showed increased hydrothermal activity (superhot liquids seeping to the surface), all reminders that Taal remained an active volcano.

Every once in awhile, however, it gets so cold up there that the sparse water molecules can actually assemble themselves into icy clouds. Conditions for the past couple of days have been conducive to the formation of such clouds as it is extremely cold in the stratosphere over the Arctic Circle with temperatures as low as -85 degrees (C). As a result, there has been an outbreak of these polar stratospheric clouds and some reports suggest they are more prevalent than ever filling as much as 25% of the sky.

As the very cold air moved over the still relatively-warm waters beneath, instability was generated in the lower part of the atmosphere and “cloud streets” formed parallel to the wind flow (i.e., from NNW-to-SSE). The “cloud streets” can then take on a flattened-appearance if they run into some warmer and more stable air aloft which acts as a lid. The inversion causes the rising thermals to “roll over” on themselves forming parallel cylinders of rotating air. The clouds streets may start a bit offshore as the cold air mass needs some time and distance moving over the water to pick up enough moisture for clouds to form. Some of these clouds are likely to have ultimately produced snow flurries or snow showers out over the warm waters of the western Atlantic Ocean. https://images.squarespace-cdn.com/content/v1/56530521e4b0c307d59bbe97/1569612646531-DOAID6MHFX32C37EIL89/EFZQ0vBXoAI64RC.jpg Image of the week gallery - Kelvin-Helmholtz wave clouds Gibraltar is a British Territory on Spain's south coast and is dominated by the Rock of Gibraltar, a 426 meter-high limestone ridge.

In spite of its location, this atmospheric feature is not linked to volcanic activity but is rather a water ice cloud driven by the influence of the volcano’s leeward slope on the air flow – something that scientists call an orographic or lee cloud – and a regular phenomenon in this region. The cloud can be seen in this view taken on 10 October by the Visual Monitoring Camera (VMC) on Mars Express – which has imaged it hundreds of times over the past few weeks – as the white, elongated feature extending 1500 km westward of Arsia Mons. As a comparison, the cone-shaped volcano has a diameter of about 250 km. Mars just experienced its northern hemisphere winter solstice on 16 October. In the months leading up to the solstice, most cloud activity disappears over big volcanoes like Arsia Mons; its summit is covered with clouds throughout the rest of the martian year. https://images.squarespace-cdn.com/content/v1/56530521e4b0c307d59bbe97/1540229649995-LGT0CGNK3TIRK0FP16EM/Wilma.png Image of the week gallery - Cat 5 Hurricane Willa Hurricane Willa has strengthened into a cat 5 storm as of Monday, October 22, 2018 and it will actually play a role in a potential nor’easter this weekend by feeding energy and moisture into the Gulf of Mexico region.

Lenticular clouds are stationary clouds that form in the troposphere, usually in perpendicular alignment to the wind direction. As air travels along the surface of the Earth, obstructions are often encountered. These include both natural features of the Earth such as mountains or hills, and man-made structures, such as buildings and other structures. These disrupt the flow of air into "eddies", or areas of turbulence influenced by these obstructions. When moist, stable air flows over a larger eddy, like those caused by mountains, a series of large-scale standing waves form on the leeward side of the mountain. If the temperature at the crest of the wave drops below the local dew point, moisture in the air may condense to form lenticular clouds.

This dry air moves in a general east-to-west fashion with the trade winds and can play a critical role in the development or intensification of tropical systems in the Atlantic Basin. In addition to this widespread extent of dry air from the western regions of Africa, sea surface temperatures have been running at below-normal levels in the eastern Atlantic and inhibiting tropical storm formation. https://images.squarespace-cdn.com/content/v1/56530521e4b0c307d59bbe97/1523212136452-Q975FYA3YTXUMOC8NX3Z/julian_alps_NW_slovenia_april_8th.jpg Image of the week gallery - Snow in the Alps A little bit of snow this winter/spring in the Julian Alps of northwest Slovenia.

Sudden Stratospheric Warming (SSW) events are among the most impressive dynamical events in the physical climate system. If history is any guide, this unfolding stratospheric warming event can result in Arctic air outbreaks for the central and eastern US in coming days. During the winter months in the polar stratosphere, temperatures are typically lower than minus 70°C. The cold temperatures are combined with strong westerly winds that form the southern boundary of the stratospheric polar vortex which plays a major role in determining how much Arctic air spills southward toward the mid-latitudes. This dominant structure is sometimes disrupted in some winters or even reversed. Under these circumstances, the temperatures in the lower stratosphere can rise by more than 50°C in just a few days. This sets off a reversal in the west-to-east winds and the collapse of the polar vortex. In response to the stratospheric warming (and associated layer expansion) at the high latitudes, the troposphere in turn cools down dramatically (with layer contraction) at the high latitudes. This tropospheric cold air can then be transported from the high latitudes to the middle latitudes given the right overall weather pattern (e.g., "high-latitude blocking"). The tropospheric response to the SSWs closely resembles the negative phase of the North Atlantic Oscillation (NAO), involving an equatorward shift of the North Atlantic storm track; extreme cold air outbreaks in parts of North America, northern Eurasia and Siberia; and strong warming of Greenland, eastern Canada, and southern Eurasia (Thompson et al., 2002). The entire process from the initial warming of the stratospheric at high latitudes to the cooling in the troposphere at middle latitudes can take weeks to unfold. https://images.squarespace-cdn.com/content/v1/56530521e4b0c307d59bbe97/1516300376935-FTJN3D05UTVA5GJ52J0V/Capture.PNG Image of the week gallery - Pennsylvania snow cover as seen from space GOES-16 with an absolutely stunning view of Pennsylvania's snow-covered topography on Thursday, January 18, 2018. https://images.squarespace-cdn.com/content/v1/56530521e4b0c307d59bbe97/1515692808558-7CU1MS58Q7P2K5I73OQD/sahara.PNG Image of the week gallery - Sahara Desert snow Landsat 8 captures snowfall in the Sahara Desert for just the third time in 40 yrs.

Dust storms are caused by strong winds passing over the loose particles of sandy soils, causing them move over the ground and fracture, freeing smaller particles -- i.e., the dust -- that become airborne and transported by the wind. Scientists estimate that, on average, about 20 teragrams of dust are suspended in the atmosphere at any given time and, about half of it is thought to originates in North Africa, due to both the abundance of dust sources there and the region's position under the subtropical jet stream, which carries dust around the world. The rest is said to come from just a handful of other well-known dust-producing regions, including northwestern China’s Taklimakan Desert, parts of Arabia, Iran, the shore of the Caspian Sea, the Lake Eyre Basin in Australia, and the area around Utah’s Great Salt Lake.   Credit: NOAA/CIRA https://images.squarespace-cdn.com/content/v1/56530521e4b0c307d59bbe97/1513024421302-VOCEX7I3ODRSDTBQ8ZD0/Picture1.png Image of the week gallery - First snowfall of the season in the eastern states MODIS imagery (right) depicts the snowcover from the Saturday, December 9th, 2017, storm with snow all the way down into the Deep South.

It created a bright fireball in the sky, which was seen by thousands of people in Germany, France, Switzerland, Austria and Luxembourg, and was reported widely by media. This remarkable image was taken by Ollie Taylor, a photographer from Dorset, UK, who happened to be on a shoot in Italy, in the Dolomites. The landscape scene shows the village of La Villa, Alta Badia, with Ursa Major seen in the background sky. At dusk on 14 November, he was setting up for a night landscape shoot at Passo Falzarego, at 2200 m altitude, in clear but chilly –6ºC weather. Ollie reports: “I was composing a shot of this scene and Ursa Major, seen above the meteor. I wanted to get it at twilight so the sky had a nice pink hue. I just decided I was not getting close enough, and was reaching for my other camera with a longer lens, luckily I left this camera exposing! “It was a stroke of luck, as it’s given me not only the meteor, but great landscape background, too.” Small lumps of rock enter our atmosphere every day, but it is rare for one to burn so brightly and to be seen by so many people. “Owing to the meteoroid’s very high speed, estimated to be at least 70 000 km/h, it super-heated the air molecules in its path as it decelerated, creating a very luminous fireball,” adds Rudiger Jehn, of ESA’s Space Situational Awareness programme. “Observers reported the meteoroid in detail, which allowed us to estimate its final fate: burning up at an altitude of around 50 km above Luxembourg.” By yesterday, over 1150 sightings had been submitted to the International Meteor Organization, which runs a website to gather sightings of such events worldwide.

While “back-to-back-to-back” La Nina episodes are not unprecedented, they are rather uncommon and analog years suggest that the third winter in this extended oceanic event is typically colder-than-normal across much of the eastern half of the nation with the coldest core of the air centered over the Upper Midwest. In addition to La Nina, another factor considered in the 2022-2023 “Winter Outlook” is the stratospheric cooling that developed earlier this year in the southern hemisphere partly as a result of unusually high levels of water vapor that were injected aloft by the powerful Hunga Tonga volcanic eruption back in January. The connection between southern hemisphere stratospheric cooling and high-latitude blocking (negative NAO) patterns in the subsequent northern hemisphere winter season is investigated. https://images.squarespace-cdn.com/content/v1/56530521e4b0c307d59bbe97/1729786021349-JOTJVDUD4ZTQDSBYQZ9X/unsplash-image-F4K_yTOmXZ0.jpg Seasonal Outlooks Gallery - 2024-2025 Winter Outlook Last winter was generally warmer-than-normal in the Mid-Atlantic region with below-normal snowfall and 2024 began with a rather strong El Nino event in the tropical Pacific Ocean. However, those warmer-than-normal water temperatures have since flipped to below-normal and this upcoming winter season is quite likely to feature weak La Nina (colder-than-normal) conditions. https://images.squarespace-cdn.com/content/v1/56530521e4b0c307d59bbe97/1713540790884-7G2572NVPW62ZGP702A7/image-asset.jpeg Seasonal Outlooks Gallery - 2024 Tropical and Summer Outlook Numerous signs point to an active tropical season this year in the Atlantic Basin with more tropical storms, hurricanes, and “major” hurricanes compared to the long-term averages. The average number of named tropical storms in an Atlantic Basin tropical season is 14.4 with 7.2 of those reaching (minimal) hurricane status, and 3.2 becoming “major” (1991-2020 baseline period). https://images.squarespace-cdn.com/content/v1/56530521e4b0c307d59bbe97/1698710746882-Z7TSS8WF19P9RTMSIRZU/image-asset.jpeg Seasonal Outlooks Gallery - 2023-2024 Winter Outlook A major change has come to the tropical Pacific Ocean since last winter with respect to sea surface temperatures and this transformation will have a big impact on the upcoming winter. Specifically, above-normal sea surface temperatures (El Nino) have replaced the cooler-than-normal conditions (La Nina) of the previous winter. In fact, the tropical Pacific Ocean uncommonly featured “back-to-back-to-back” La Nina winters with cooler-than-normal water temperatures, but drastic changes began to take shape earlier this year. https://images.squarespace-cdn.com/content/v1/56530521e4b0c307d59bbe97/1682726956822-DK3U6HF7VLL9BCPD9OL5/unsplash-image-td7G4W1HSIE.jpg Seasonal Outlooks Gallery - 2023 Tropical and Summer Outlook Tropical activity is likely to be nearly normal this season in the Atlantic Basin with competing factors in the Atlantic and Pacific Oceans. In a normal Atlantic Basin tropical season, there are about 14 named storms, 7 hurricanes, and 3 of those actually attain “major” classification status (i.e., category 3 or higher on the Saffir-Simpson hurricane wind scale). https://images.squarespace-cdn.com/content/v1/56530521e4b0c307d59bbe97/1665770620552-DMKWZ48YHOFXIYL3ZSDJ/unsplash-image-fgm1EVnFPWs.jpg Seasonal Outlooks Gallery - 2022-2023 Winter Seasonal Outlook The past two winters have featured La Nina conditions in the equatorial part of the Pacific Ocean and all signs point to a third such event for the winter of 2022-2023.

In addition to La Nina, another factor considered in the 2022-2023 “Winter Outlook” is the stratospheric cooling that developed earlier this year in the southern hemisphere partly as a result of unusually high levels of water vapor that were injected aloft by the powerful Hunga Tonga volcanic eruption back in January. The connection between southern hemisphere stratospheric cooling and high-latitude blocking (negative NAO) patterns in the subsequent northern hemisphere winter season is investigated. https://images.squarespace-cdn.com/content/v1/56530521e4b0c307d59bbe97/1651253748596-D0ZE1LOHRUZ4594H2JWS/unsplash-image-keSFbPQAJRE.jpg Seasonal Outlooks Gallery - 2022 Tropical Season and Summer Outlook We are likely headed to another tropical season in the Atlantic Basin with more activity than usual, but not quite as active as the last couple of years. The average number of named storms in an Atlantic Basin tropical season is 14.4 with 7.2 of those reaching minimal hurricane status and 3.2 becoming “major” In comparison with the 1991-2020 baseline period). Based on the overall analysis of current and forecasted atmospheric and oceanic conditions, I expect around 18 named storms in the Atlantic Basin this tropical season with around 8 reaching hurricane status and of those perhaps as many as 4 to achieve “major” classification level. https://images.squarespace-cdn.com/content/v1/56530521e4b0c307d59bbe97/1635183583497-T5TEOV8I6MRHBLDCECQX/image-asset.jpeg Seasonal Outlooks Gallery - 2021-2022 Winter Seasonal Outlook The winter season of 2020-2021 featured La Nina conditions in the equatorial part of the Pacific Ocean which then weakened to near neutral status during the spring and summer of this year. New cooling has formed in the same region and it appears that a second year La Nina will take place for the upcoming winter season. Sea surface temperature anomalies in the central Pacific Ocean were but one of several factors considered in the 2021-2022 “Winter Outlook”. https://images.squarespace-cdn.com/content/v1/56530521e4b0c307d59bbe97/1618881884365-RVH3OHBWM9TQ9L4VY617/unsplash-image-9r2iRVbcDlA.jpg Seasonal Outlooks Gallery - 2021 Tropical Season and Summertime Outlook https://www.youtube.com/watch?v=_yM--ed_LY4 The number of named tropical storms this year is likely to be above-normal in the Atlantic Basin, but not as high as the very active 2020 tropical season. While the number of named tropical storms may be above-normal, the number that actually attain hurricane classification and “major” status (i.e., category 3 or higher) is likely to be right near normal. https://static1.squarespace.com/static/56530521e4b0c307d59bbe97/5d8434eee707a67e06d9e34a/5d84351ea958ad75de669fce/1568945438964/ Seasonal Outlooks Gallery https://images.squarespace-cdn.com/content/v1/56530521e4b0c307d59bbe97/1603417160101-EWJQ5DP1642JB1OLI4XZ/image-asset.jpeg Seasonal Outlooks Gallery - 2020-2021 Winter Seasonal Outlook Numerous factors have been examined for this year’s “Winter Outlook” including the strong prospects for a moderately strong La Nina event in the tropical Pacific Ocean, somewhat favorable signs for high-latitude blocking events, and an analysis of “analog” winters that featured similar oceanic conditions to today’s environment. Many signs point to colder-than-normal conditions this winter season across the northern US including in the Mid-Atlantic region and the virtually snowless winter of last year is quite likely not going to repeat itself. https://images.squarespace-cdn.com/content/v1/56530521e4b0c307d59bbe97/1587729992995-QCQS1M3G3SMOO9Y34SGL/image-asset.jpeg Seasonal Outlooks Gallery - 2020 Tropical and Mid-Atlantic Outlook The overall numbers are likely to be above average this year in terms of the number of tropical storms and hurricanes in the Atlantic Basin (includes the Caribbean Sea and Gulf of Mexico) with around 13 named tropical systems, 7 hurricanes, and 3 majors (i.e., category 3, 4 or 5 on the Saffir-Simpson Hurricane Wind Scale). https://images.squarespace-cdn.com/content/v1/56530521e4b0c307d59bbe97/1572050695961-JQ2Z0K9QTE5EQNOCK3XE/image-asset.jpeg Seasonal Outlooks Gallery - 2019-2020 Winter Outlook The Mid-Atlantic region should experience slightly colder-than-normal temperatures this winter season and slightly above-normal snowfall amounts based upon such factors described above as current sea surface temperature anomalies, the likelihood of high-latitude blocking events, and a comparison with analog years. https://images.squarespace-cdn.com/content/v1/56530521e4b0c307d59bbe97/1568946525829-YV0O5WHND17N16ZYZY9A/image-asset.jpeg Seasonal Outlooks Gallery -

It was a typical hurricane season with an average number of named storms, a slightly above-average number of hurricanes, a slightly below-average number of major hurricanes. The state of Florida was hit the hardest in the US during last year’s tropical season with direct hits just six weeks apart. https://images.squarespace-cdn.com/content/v1/56530521e4b0c307d59bbe97/987609ce-11ab-4597-a67d-2aab903b3daa/5_IRI_CPC_April.PNG 2023 Tropical and Summer Outlook - Make it stand out The graph shows forecasts made by dynamical and statistical models for SST in the Nino 3.4 region for nine overlapping 3-month periods. Note that the expected skills of the models, based on historical performance, are not equal to one another. The skills also generally decrease as the lead time increases. Thirdly, forecasts made at some times of the year generally have higher skill than forecasts made at other times of the year--namely, they are better when made between June and December than when they are made between February and May. Differences among the forecasts of the models reflect both differences in model design, and actual uncertainty in the forecast of the possible future SST scenario.
