Weather in Denver: Arctic air flows into Colorado bringing cold and snow

Thursday was declared the first weather alert day thanks to an arctic cold front bringing freezing temperatures and more snow.

Until the front arrives late Wednesday evening, Tuesday will be relatively calm and remain cool across Colorado. It will be the eighth consecutive day of below normal temperatures in Denver, and there are at least 5 days to go before temperatures could reach above normal just before Thanksgiving.



The coldest days of the almost two-week cold snap are Thursday and Friday. High temperatures in the Denver metro area will be in the 20s for both days, and some areas along the city corridor may remain in the teens on Friday. It’s unseasonably cold weather for so early in the cold season. Denver should remain below freezing for about 66 hours from Wednesday night through Saturday morning.



The cold air will also bring snow, which begins as early as sunrise Thursday around Fort Collins, Loveland and Greeley. Snow then slowly moves south toward Denver and Boulder as the day progresses, and there is a strong likelihood of snow along most of the city’s Thursday afternoon and evening commute corridor.

The snow forecast is similar to what many neighborhoods received Monday evening and Tuesday morning. Many areas, including most of Denver, should see 3 to 4 inches of fluffy snow. Areas further east should decrease while Boulder and Larimer Counties could reach up to 6 inches, including in Boulder and possibly Fort Collins.



Most of the snow will end before sunrise on Friday and the main weather story over the weekend will be the cold. If clouds clear enough by Friday night, Saturday morning temperatures could be in the single digits.

The mountains will also get snow, but nothing unusual for the highlands. Summit County’s mountains will grow 1 to 5 inches tall, while mountains farther north around Winter Park, Rocky Mountain National Park and the Rabbit Ears Pass area could grow as high as 8 inches.

Looking ahead to next week, temperatures will finally warm up to 50 degrees from Monday. The weather should also be good for car and plane travel in Colorado in the days leading up to Thanksgiving.
