Cooler, unsettled Sunday; some snow Monday along Front Range

12:00 noon, Saturday, February 14, 2015

We are not expecting a severe cold wave or major snowstorm, but cooler, unsettled weather is expected Sunday. And if it doesn’t snow Sunday, there is a better chance for some snow Monday. The cool-down is likely to last through Tuesday before a return to milder weather around midweek.

A cold front Sunday is likely to bring temperatures back to seasonal averages (highs in the 40s for Denver-Boulder). Some Pacific moisture Sunday afternoon and evening will probably contribute to a few inches of snow in the mountains, mainly north of I-70 and in the Cheyenne area (maybe some brief heavy snow in the Laramie Range). For the Denver-Boulder-Fort Collins area, rain changing to snow Sunday afternoon should be pretty minor if it occurs, with accumulation ranging from zero in many areas, to an inch or two in a few narrow bands.

It is likely to be colder on Monday with some periods of snow, especially in and along the Front Range. Accumulations are likely to be 0-2 inches away from the foothills (places like DIA and Longmont) with 2-4 inches probable in and near the foothills. There is still uncertainty and I’d say there is a 20% chance of less than 2 inches everywhere and a 20% chance of heavier than 4″ in the Denver-Boulder area.

The San Juan mountains in southwestern Colorado are not likely to get much at all from this series of weak storms.
