The 3-day weekend will end much colder than the first two days, with some snow, mainly north of Colorado Springs. The cold surge is already through Casper, WY and is likely to slide down the Front Range tonight. There may be some light snow or freezing drizzle by Monday morning, and a better chance for snow along with even colder air Monday afternoon and night.
Widespread accumulations of 1-4 inches can be expected from the Denver area northward, but there will probably be some narrow southwest-northeast bands of heavier snow resulting in some areas getting 3-6 inches, mainly Monday afternoon or night. With temperature in the 20s and maybe even colder by late day Monday, expect wintry road conditions.
As you go south from Denver the chance for snow decreases, with just a small chance for accumulations in Colorado Springs and Pueblo. Snowy conditions are likely at many of the high passes as well. North and west of Cheyenne heavy snow and wind may force some road closures.
Very cold weather will continue through Tuesday.
