DENVER – Today’s weather story involves a lesson in physics.
Seasonal air for late December is flowing into the state from the west and coming down the Rockies which is why the day started so much warmer in the foothills than it did in Denver.
Meanwhile, at the same time … much colder air is moving into Colorado from the east. This sets up an inversion as seen in the picture below.

Since the cold air is shallow, dense and heavy (less than 2,000 feet thick) as it flows in from the east it stops at the foothills because it can’t rise up in elevation.
The result is a crazy line with a wide temperature contrast right along the foothills and Interstate 25.
Because of this temps will be all over today and could vary as much as 10 to 20 degrees over a short distance. The higher you climb the warmer it will be and the lower you go the colder.
I’m going to shoot right in the middle and say highs around 40 in Denver but again, some will never get out of the 20s today and others could hit 50! It’s all because of this crazy inversion and the battle of two different air masses along I-25.
Tonight a deeper batch of cold air will move in and it should keep us locked in the deep freeze all day tomorrow with highs only in the 20s. Patchy fog and flurries are possible tonight and Sunday.
A cold front that rolled through on Monday night drastically dropped our temperatures and brought more wintery weather to Colorado. We were more than 30 degrees cooler for many areas of the Front Range and plains on Tuesday afternoon.
A mix of snow and rain on and off through the day on Tuesday, and that precipitation should mostly wrap up after 9:00 pm.
Overnight into Wednesday, expect some cloudy skies and breezy conditions.
Skies clear on Wednesday and we should have a gorgeous day with highs back to the low to mid 60s.
The warm up will be short lived thanks to another passing storm on Thursday. A chance for rain showers will also return on Thursday before sunny, dry, and warmer weather for Friday and Saturday.
In the mountains, plan on snow showers mainly east of Vail Pass through Tuesday night with up to 5 inches above 9,500 feet. Dry weather will return to the high country for Wednesday.
After that, warmer and sunny to end the week and start the weekend.
