A large storm system from the Pacific will be bring winter back this weekend through Tuesday. Initially the Front Range foothills and plains will be mild on Saturday and turning colder Saturday evening with the main snow likely on Monday and Monday night.
Saturday and Sunday:
Expect periods of heavy snow and blowing snow in mountain areas and high passes along and west of the continental divide, mainly on Saturday. For the Front Range foothills and urban corridor, mild weather on Saturday will be replaced by colder weather Saturday evening through Sunday. Localized snow, or rain changing to snow, may occur Saturday evening. The precipitation is likely to be oriented in narrow east-west bands. Most areas will probably get little or nothing, while a few locations may get a quick burst of snow that produces 1-2 inches. Sunday will probably be a mainly dry but colder day.
The main storm system is likely move east across northern New Mexico on Monday into early Tuesday morning bringing widespread snow to the state, especially the eastern plains and foothills. Current indications are that the heaviest snow may stay south of Denver.
South Denver suburbs and southward: most likely range is 6-12 inches with some chance more depending on exact development of the storm.
Denver-Broomfield-Boulder: at least 3-6 inches, with a 50-50 chance of 6-10 inches, and just a small chance of more than 10.
Larimer & Weld counties, and Cheyenne area: most likely range of 2-6 inches, with a small chance that a northward shift could bring heavier snow.
Expect snowy travel in the urban corridor Monday and Tuesday morning. I will update over the weekend.
