The chill will slowly ease over Colorado
A gradual thaw on the way
DENVER - We are seeing signs of change, or perhaps hearing them as strong winds begin to sweep the Arctic air away from Colorado. Winds have been howling on the west side of Sheridan Boulevard and will continue to blow hard tonight and Tuesday morning.
The strong, cold Arctic high pressure system that has kept Colorado and much of the central United States in the deep freeze is starting to weaken and move slowly to the east. The core of that high is now positioned over Minnesota and the bitter cold air is flowing around that high from the North Pole all the way to the Gulf of Mexico.
The high will slowly ease off to the east and take the coldest air into the Great Lakes and New England - those poor folks will stay in the deep freeze through the end of this week. In Colorado, the Arctic air will ebb off to our east by Wednesday, allowing temperatures to rebound to the freezing mark.
In addition, the supply of really cold air over central and northern Canada has diminished as the Arctic Invasion has stretched so far to the south. This has sapped the strength of the air mass as temperatures in central Canada are now in the zero to minus 10 range with a few places as cold as 20 below.
Lows tonight in Denver will drop to zero to 5 above and highs on Tuesday will be in the low 30s. More sun and temperatures above freezing should help to melt some of the snow still stuck to the side streets.
By Thursday and Friday, we expect temperatures in Denver and along the I-25 Corridor should get back to the low to mid 40s. There will be some periods of light snow for the mountains, but dry weather is expected for Denver and the I-25 Corridor.
The mountains - especially the high mountain valleys, will stay very cold! The cold air is very dense and hard to move out of the high valleys, so a prolonged cold snap is expected. It will take a big storm, with lots of snow and wind, to scour the cold air out of those valleys.
Although no major storms are expected in Colorado for the next 5-7 days, the mountains will get a few periods of light to moderate snow - helping to boost the already amazing skiing conditions! Those minor storms will not be enough to get the chill out of those valleys, so stay bundled in Fraser, Gunnison and Alamosa!
