Heat Taking Aim on Central US

The big weather story this week continues to be the heat taking aim on the central United States, including eastern Colorado.

An area of high pressure in the upper-levels of the atmosphere has taken residence over the central Plains.  Temperatures under and near the high have climbed in to the 90°s and in some cases 100°s.  Along with the high temperatures, humidity is high across the central U.S.  Heat indices (the feels like temperature) hace climbed to near 110° as far north as Minnesota.

The upper-level high will slowly move east over the next 48 hours.  Eventually, it will begin to retrograde to the west.

As the upper-level high controls the weather pattern over eastern Colorado, monsoon moisture will remain over Arizona and Utah.  Later this week some of the moisture will begin to return to the mountains of southern Colorado and eventually the I-25 corridor.  I introduce a chance for isolated showers and thunderstorms for places like Canon City and Woodland Park starting Wednesday.

LABOR DAY WEEKEND

As of now, computer models are suggesting there will be enough moisture around southern/southeastern Colorado for there to be a chance of showers and thunderstorms.  Also, with the moisture around, skies will be partly to mostly cloudy, especially for areas closer to the foothills.  Temperatures will also be held down due to the clouds and showers/thunderstorms.  Highs will likely be in the 80°s.
