Wednesday

Mostly sunny, very warm, upper 80’s

Discussion

There is not much change to the overall pattern of the last few days. High pressure in the upper atmosphere stretches from the Four Corners region to the southern Plains and will continue to generate very warm conditions in the southern Rockies for the next several days. Enough monsoonal moisture will be around in the southern Rockies to allow for the slight chance of afternoon and evening showers and thunderstorms. The best chance for these showers and thunderstorms will be over the mountains with little chance of coverage over the plains. High temperatures will stay slightly above normal over the next several days generally reaching the upper 80’s in and around the Denver metro region.

11:00 AM | Interesting activity in recent weeks at both polar regions - North Pole may be experiencing one of its coldest summers ever and the southern hemisphere sea ice areal extent is again at a record high for the date

Discussion

Some interesting activity has been occurring in recent days at both polar regions in terms of cold weather and sea ice areal extent. To begin with, this is turning out to be one of the coldest summers ever recorded in and around the North Pole according to the Danish Meteorological Institute (DMI). Furthermore, on the other side of the globe, the southern hemisphere sea ice areal extent is once again right near a record high for the date and it has a chance to end up near all-time record highs for the region over the next several weeks.

The DMI, Center for Ocean and Ice, estimates the daily mean temperature of the Arctic region north of 80 degrees using analysis data (00 and 12Z) from the European computer forecast model for all model grid points inside that area. The DMI produces a chart plotting this daily mean temperature as a function of the day of the year against the average of the daily mean temperature for the period from 1958 to 2002. In fact, the daily mean temperatures in this Arctic region has remained below the climatological normal for more than 4 months now and it has dropped below freezing far earlier than normal for this area. Normally, the drop below freezing does not occur until the middle part of September. The sea ice areal extent in the northern hemisphere continues to run at well below normal levels, but with the colder-than-normal weather north of 80 degrees this summer, there has been a noticeable uptick in northern hemisphere sea ice areal extent in recent weeks relative to several recent years. The overall northern hemisphere sea ice areal extent has generally been below normal since the mid-1990s at which time the northern Atlantic Ocean developed warmer-than-normal sea surface temperatures which is tracked by meteorologists through an index called the Atlantic Multidecadal Oscillation (AMO). The AMO index switched to a warm or positive phase in the middle 1990s reflective of an oceanic cycle of warmer-than-normal sea surface temperatures. Meanwhile, the southern hemisphere which is moving through their winter season continues to impress with its sea ice areal extent. Indeed, the most recent measurements suggest it is near a record high for the date and may come close to all-time record highs in areal extent over the next several weeks using records that go back to the beginning of the satellite era (1979).

Discussion

An upper level low pressure system will drift only slowly away from us over the next few days leaving a general trough across the region through the weekend. The late night and early morning pattern of low clouds and fog along coastal regions will resume this weekend along with seasonably cool temperatures. We’ll have to monitor the remnants of a tropical disturbance for the beginning of next week as it could increase slightly the chances for showers and thunderstorms across the region at the same time slightly milder air heads our way.

Tonight

Mostly cloudy, mild, slight chance for showers and thunderstorms, lows by morning in the low-to-mid 60’s

Friday

Partly sunny, very warm, chance for showers and thunderstorms, near 90

Tuesday

Mostly sunny, very warm, upper 80’s

Discussion

High pressure in the upper atmosphere stretches from the Four Corners region to the southern Plains and will continue to generate very warm conditions in the southern Rockies for today. This upper level ridge will shift eastward by the weekend and this will allow for moist air to flow into the region from the Southwest US. As a result, there will be the threat for scattered afternoon and evening showers and thunderstorms from late this week right into early next week.

Discussion

High pressure in the upper atmosphere over the state will continue our very warm weather pattern for the next several days. An upper level disturbance will move to the north of the region in the overnight hours keeping the chances alive for scattered showers and thunderstorms. This disturbance will also bring into the southern Rockies somewhat cooler weather for Thursday.

1:20 PM | Suddenly, the sun has become quite active; Coronal Mass Ejection on the farside of the sun and a small comet plunges to its demise early today (both captured on video) at the same time sunspot activity increases dramatically

Discussion

There has suddenly been an uptick in action on the sun as sunspot activity has increased dramatically in recent days from a rather quiet picture just a few days ago to one with numerous sunspots now facing the Earth. In addition to the increasing sunspot activity, there was a coronal mass ejection (CME) early this morning on the far-side of the sun. It is likely that this CME will not have an impact on the Earth’s upper atmosphere since it took place in a “non-Earth facing” direction. Finally, a small comet plunged into the sun early this morning at just about the same time the sun expelled the CME. Not surprisingly, the comet did not survive its encounter with the sun as it vaporized furiously upon approach. The comet was still millions of kilometers away from the sun when the explosion got underway. Amazingly, NASA’s Solar and Heliospheric Observatory (SOHO) captured on video both the CME and the small comet disintegration from earlier today. We’ll continue to monitor the sun over the next several days to see if the uptick in sunspot activity produces any Earth-facing CMEs.

Discussion

High pressure in the upper atmosphere over the Southwest US will continue our very warm weather pattern for the next several days. An upper level disturbance will move over the Great Basin region today and across Colorado overnight increasing the chances for scattered showers and thunderstorms later today and through the day on Wednesday; especially over mountainous regions. By late this week, the upper air ridge will begin shifting eastward over the central Great Plains and Colorado will come under an increasingly moist southwesterly flow of air which will continue the threat for scattered showers and thunderstorms during this upcoming weekend. Elsewhere, the Atlantic remains rather quiet for the time being as far as tropical activity is concerned, but the sun has become somewhat more active with numerous sunspots now visible on the Earth-facing side.

6-Day Forecast

Today

Mostly sunny, hot, highs near 95 degrees

Tonight

Partly cloudy, mild, lows by morning in the lower 60’s

Tuesday

Mostly sunny, hot, slight chance for showers and thunderstorms, low 90's

Tuesday Night

Partly cloudy, mild, low-to-mid 60’s

Discussion

High pressure in the upper atmosphere over the Southwest US will continue our very warm weather pattern for much of the week. Highs today will climb well into the 90's and should reach or slightly surpass the 90 degree mark for much of the week. Enough moisture will be in the picture across the southern Rockies to continue the slight chance for scattered afternoon and evening showers and thunderstorms tomorrow and Wednesday, but today should be rain-free.
