Get ready for a long snowy period Sunday night through Monday night, and even lingering in some places through Tuesday morning. Some of the coldest weather of the season will be with us at least through midweek.
Here is what this storm is:
A large, moderately organized storm that will produce a long period of snow, mainly light to moderate intensity, but some heavy snow is possible. It’s hard to pin down when the heavy snow might occur, but Monday afternoon or early evening seems most likely. Expect significant impacts to ground and air travel.
Most likely accumulation ranges through Tuesday morning:
1-2 feet: mountains and upper foothills (the high end of that range unlikely north of Boulder County)
10-16 inches: south Denver suburbs (incl. Castle Rock, Littleton, Aurora)
8-14 inches: Colorado Springs, Denver, DIA, Broomfield, Boulder
6-10 inches: Longmont, Lyons, Fort Collins
4-8 inches: Cheyenne, northern Weld County
Considerable blowing snow along and east of I-25
