Weather Discussion

The low-pressure system that blanked the State with snow over the past few days has moved off into eastern Kansas leaving partly cloudy to mostly sunny skies across the area. Colder northwest flow is keeping temperatures in the in the high twenties in the Northern and Central Mountains as well as in the North San Juan zone and low thirties in the South San Juan and the Sangre de Cristo zones. Northwest winds have been averaging in the 15 to 20 mile per hour range above 11,000 feet across all of Colorado’s mountains with wind gusts reaching into the 40’s in parts of the Northern Mountains. 

On Sunday night, clouds will increase as a moist northwest flow sets up across the Northern Mountains. Expect snow showers along and north of U.S. 50. Snow accumulations should be less than two inches. Stronger winds will continue and blowing and drifting snow is likely at ridge top levels. 

On Monday, winds shift a bit more westerly. Models show a couple of embedded shortwave troughs passing through the area early Monday morning. This may cause an uptick in snowfall particularly across the northern mountains. Ridge top winds will remain in a good range for snow transport and gusts may exceed 50 miles per hour particularly along the Continental Divide. Daytime high temperatures should warm four or five degrees from Sunday’s highs. 

On Monday night, a few showers may linger in the Northern Mountains. Westerly winds will calm a bit; however, ridge top winds will still be capable of moving snow around in avalanche starting zones. 

Current models show another low-pressure trough moving over the area on Tuesday.  Expect another round of snow showers over the mountains on Tuesday afternoon into Wednesday morning. On Wednesday, high pressure builds back over Colorado. Expect skies to clear and temperatures to make a dramatic jump.
