Each day during this 3-day weekend will be colder than the one before so that by Monday the entire region should experience very cold temperatures. Some snow is possible throughout, but for the Front Range foothills and urban corridor the best chance for accumulation is Sunday evening through Monday.
Snow will be mainly near the continental divide today where there may be some wintry travel at the high passes. Some flurries or sprinkles may break off and move over the foothills and urban corridor, but little or no accumulation is expected. Although temperatures are likely to get no better than the 30s, today will be the “warm” day of the weekend.
Temperatures will likely climb to the 30s in the low elevations Sunday before an arctic front late in the day plunges temperatures into the single digits Sunday evening. Monday and Tuesday are likely to be mainly cloudy with temperatures reaching the teens to near 20 and falling to within a few degrees of zero at night.
Snow: For the foothills and urban corridor accumulating snow is likely to accompany the very cold temperatures Sunday evening and Monday and possibly extending intermittently into Tuesday. The most (3-6″) will probably occur in and near the mountains and foothills of Boulder, Broomfield, Jefferson, Gilpin, and Douglas counties (including Boulder, Nederland, Castle Rock, and the west/south side of Denver). As you go northeast there may only be a dusting to an inch in Weld County, eastern Larimer County, DIA, and around Cheyenne.
