7:00 AM | Snow is in the forecast even though April begins tomorrow

6-Day NYC Forecast

Today

Early sunshine will give way to a quick increase in clouds, rain should break out this afternoon mixed with snow at times; especially, to the north and west of the metro region, cold, highs in the low 40’s

Tonight

A mix of rain and snow could change to all snow before ending later this evening, cold, lows not far from 30 degrees

Wednesday

Mainly sunny, breezy, cold, low-to-mid 40’s

Wednesday Night

Mostly clear, cold, upper 30’s for lows

Thursday

Mainly sunny, becoming breezy and much milder, mid-to-upper 50’s

Friday

Mostly cloudy, quite breezy and even milder with showers likely, low-to-mid 60's

Saturday

Lingering morning showers; otherwise, mostly cloudy skies, breezy and colder, low 50's

Sunday

Mostly sunny, quite chilly for this time of year, near 50 degrees

Discussion

Yet another disturbance will drop to the southeast today from the Great Lakes region and it should generate rain in the area this afternoon and evening and there can be snowflakes mixed in at times; especially, to the north and west of the metro region. In areas to the north of Route I-80, today's event will feature more snow than rain and higher elevation locations like in NW NJ can receive a few inches of snowfall by later tonight. Precipitation winds down later this evening from the fast-moving clipper system and Wednesday will turn out to be breezy and cold for the first day of April. Much milder air will advance northward into our region on Thursday and then Friday stays quite mild, but showers will be quite likely as the next cold front approaches from the northwest. Colder air will follow the late week frontal system just in time for the upcoming Easter weekend.

7:00 AM | An active start to the week and snow is possible with Tuesday's disturbance; much milder on Thursday and Friday

6-Day NYC Forecast

Today

Showers of rain or snow will pull away from the region this morning and skies should remain mostly cloudy for the afternoon, becoming breezy and milder, highs in the low-to-mid 50’s late in the day

Tonight

Partly cloudy, chilly, lows in the mid 30’s

Tuesday

Increasing clouds, cold, snow or a mix of snow and rain likely to develop for the mid-and-late afternoon hours, highs in the low 40's

Tuesday Night

Snow or snow mixed with rain during the evening, small accumulations possible on grassy surfaces, cold, lows near 30 degrees

Wednesday

Mainly sunny, cold, breezy, low 40’s

Thursday

Mostly sunny, milder, mid-to-upper 50’s

Friday

Mostly cloudy, quite mild, showers likely, near 60 degrees

Saturday

Mostly cloudy, colder, breezy, chance for showers, upper 40’s

Discussion

After a weekend with winter-like cold, temperatures will moderate somewhat by later today and there should be a noticeable warm up later in the week with 60 degrees possible on Thursday and Friday. A weak disturbance swinging by to our north this morning produced clouds and showers of rain or snow, but it will push away this afternoon and skies should clear. High pressure will then take control for tonight and early Tuesday, but then yet another disturbance will drop to the southeast from the Great Lakes region and it should produce snow or a mix of rain and snow in the area later tomorrow and early tomorrow night and there is even the chance for some small grassy accumulations. Following that second disturbance, Wednesday looks to be quiet, but chilly, and then it’ll turn significantly milder on Thursday and Friday ahead of the next cold frontal system. That front is likely to generate showers in the region on Friday and then usher in colder air for the upcoming Easter weekend.

7:00 AM | Much cooler today following yesterday's spike to 62 degrees at Central Park...winter-like cold for the weekend...snow showers even possible at any time from later today through Saturday

6-Day NYC Forecast

Today

Occasional showers this morning and then remaining mostly cloudy this afternoon with a possible rain or snow shower, much cooler than yesterday with highs in the upper 40's

Tonight

Mostly cloudy with the chance for a few rain showers early and snow showers late, cold, lows near freezing by morning

Saturday

Mainly cloudy, even colder, a few snow showers are possible, cold, near 40 degrees for highs

Saturday Night

Mostly cloudy, very cold, low-to-mid 20's

Sunday

Mainly sunny, cold, low 40’s

Monday

Partly sunny, breezy, not as cold, maybe a shower, low 50’s

Tuesday

Partly sunny, breezy, cool, low 50’s

Wednesday

Partly sunny, a bit milder, low-to-mid 50’s

Discussion

After a spike in temperatures on Thursday to 62 degrees at Central Park, it has turned much cooler this morning following a cold frontal passage and we'll return to winter-like cold for the weekend. The transition to winter-like cold will continue to generate some rain around here this morning and then, as colder air continues to pour into the region, there is the chance for snow shower activity at just about any time from later today through tomorrow. The atmosphere in the overnight hours and on Saturday will be rather unstable around here thanks to an impressive upper-level wave of energy and it’ll likely be cold enough for any precipitation to fall in the form of snow. The weather quiets down on Sunday, but it’ll remain quite cold for this time of year. In fact, the cold this weekend will not only be quite impressive in the Mid-Atlantic region for late March, but it could turn out to be a widespread low temperature record-breaker come early Sunday morning in many parts of the eastern third of the nation.

Tuesday

Partly sunny, breezy, cool, low 50’s

Discussion

A warm front passed through the region late yesterday and temperatures today will spike in the I-95 corridor; but this warm up will be rather short-lived. A strong cold front arrives this evening with showers and scattered strong thunderstorms and it will put an end to the quick burst of milder weather. Temperatures will begin a downward trend on Friday and that trend will continue into the weekend which will end up being well below normal for late March. In fact, this winter-like cold is likely to be accompanied by snow shower activity anytime from later tomorrow into Saturday as there will be lots of energy in the upper part of the atmosphere generating unstable conditions at the same time the colder air pours into the Mid-Atlantic region.

Saturday

Discussion

A cold air mass for this time of year resides this morning in the Northeast US and it is anchored by strong high pressure. That high pressure area will shift off the coast on Tuesday and it’ll turn milder at mid-week. In fact, Thursday appears to be the warmest day of the week, but it also looks like it’ll be wet as well as well as mild. The mid-week warm up won’t last long; however, as another strong cold front will reach the east coast late Thursday and we’ll turn colder again by the end of the work week as this overall colder-than-normal weather pattern continues into April. There will be lots of energy in the upper atmosphere post-cold frontal passage and we'll have to watch for the possibility of a storm to form in the cold air near the east coast later Friday or Saturday.

One final note, here is a small sampling of snowfall totals from last Friday’s event (not necessarily the last one):

DC/Baltimore region: Reagan National Airport trace, BWI Airport 1.1”, Germantown, MD 2.0”, Manassas, VA 1.0”, College Park, MD 1.3”

Philly area: PHL Airport 3.9”, King of Prussia 5.2”, West Chester, PA 5.5”, Exton, PA 5.0”, Chadds Ford, PA 3.9”, Media, PA 6.0”, Perkasie, PA 6.0”

New York City region: Central Park, NY 3.2”, Battery Park, NY 4.5”, LGA Airport, NY 4.6”, Islip, NY 5.3”

2:00 PM | **Snow has tapered off in DC, but will continue for awhile from Philly to NYC**

Discussion

While precipitation is winding down across the DC metro region, there are still several hours to go in the corridor from southeastern PA to New York City where heavy snow is now being reported (Central Park). Accumulation amounts in the DC metro region ranged from a trace at Reagan National Airport (DCA) to around 3 inches or so in portions of Montgomery (MD) and Loudoun Counties (VA) – well to the west and north of the District. In some suburban locations in SE PA snowfall amounts are already closing in on 4 inches or so on grassy surfaces and even many roadways are getting covered. Despite the high sun angle in late March, roadways will continue to be slippery into the evening during periods of heavy snow and visibilities will be a problem. The snow will continue at varying intensities right into the early nighttime hours and then could taper off late tonight from Philly to NYC as light freezing drizzle or even light snizzle (i.e., snow drizzle). Accumulations of 3-6 inches are expected on average from the suburbs of Philly across central and northern New Jersey and into the NYC metro region. There will be a lot of melting on Saturday as it gets noticeably milder, but the overall colder-than-normal weather pattern continues right into April. It’s quite amazing to see snow at this hour in places like Atlantic City, NJ and Philly, PA with the temperature at 33 degrees in both places considering the fact that the normal high for March 20th is around 54 degrees. On a more positive note, this storm is very photogenic. The wet nature of the snow is clinging to tree limbs and surrounding early spring flowers that have begun to bloom in parts of the area.

Discussion

The first day of spring will feature a total solar eclipse, "new" supermoon (http://vencoreweather.com/2015/03/17/150-pm-strong-geomagnetic-storm-currently-underway-and-could-cause-northern-lights-into-this-evening-friday-will-feature-three-celestial-events/) and accumulating snow in much of the Mid-Atlantic region. Cold air made a return to the region late Tuesday night and Wednesday and today accumulating wet snow will make a return on the same day that winter officially comes to an end. Snow develops later this morning and it will come down heavily at times later today. Slippery spots are likely on the roadways for the evening commute. Low pressure is organizing this morning over the Carolinas and it will gradually intensify as it moves to the northeast. The precipitation doesn’t wind down until later this evening.

1:00 PM | ***Spring officially begins on Friday and old man winter is saying “not so fast”… accumulating snow in the I-95 corridor***

Discussion

Astronomical spring begins late tomorrow and old man winter is saying “not so fast”. In our transition back to a winter-like pattern, cold air made a return to the region late Tuesday night and Wednesday and now it appears very likely that accumulating wet snow will make a return on the same day that winter officially comes to an end. Accumulations are likely in all areas along the I-95 corridor and given the time of year and the fact that much of this snowfall will occur during daytime hours, they are quite likely to be highly dependent on elevation and surface type. As a result, expect wide ranges of accumulations across metro regions compared-to-normal on Friday with the highest amounts on grassy surfaces in elevated locations to the north and west of the big cities.

Low pressure will organize early Friday over the Carolinas and then gradually intensify as it moves to the northeast. Precipitation will overspread the I-95 corridor late tonight or early Friday - depending on location - and it should begin as accumulating snow in most areas. In the DC metro region, the snow will mix with and then change over to plain rain later in the morning, but it should hold on as primarily snow in the N and W suburbs of Philly and NYC during much of this upcoming event. The precipitation doesn’t wind down until later tomorrow evening in most areas. Slippery conditions can be expected on the roadways on Friday as the snow will come heavily at times during this event. On a positive note, the storm on Friday could be very photogenic. The wet nature of the snow could cling to tree limbs and surround early spring flowers that have begun to bloom.

Here are the details for each metro region in the Mid-Atlantic I-95 corridor:

DC region: Snow or rain that will quickly change to snow will develop after midnight and continue into early Friday morning. The snow should then mix with and change to plain rain later in the morning, but not before there are accumulations on the order of a coating to 2 inches in the District and nearby places to its south and east, 2-4 inches in the far N and W suburbs. The highest accumulation amounts should take place on grassy surfaces in elevated locations well to the west and north of the District. The Eastern Shore and Delmarva Peninsula regions should receive an inch or less of snowfall on Friday.

Philly region: Snow should break out right around daybreak and then continue through much of the day. There is a chance that the snow mixes with rain and/or sleet later in the day; especially, in Philly and nearby points to the south and east, but it could remain as all snow well to the north and west of the city. Accumulations expected are on the order of 2-4 inches in and around the immediate Philly metro area, 3-6 inches in the N and W suburbs. The highest accumulation amounts should take place on grassy surfaces in elevated locations well to the north and west of Philly. Southern New Jersey should receive a coating to two inches, central and northern New Jersey should end up in the 3-6 inch range.

NYC region: Snow should begin early Friday and continue through much of the day. There is a chance that the snow mixes with rain and/or sleet later in the day in the NYC metro region and nearby points to the south and east, but it is likely to remain as all snow to the north and west. Accumulations on the order of 3-6 inches are likely with the highest amounts in that range on grassy surfaces in elevated locations to the west and north of NYC.
