WWUS45 KBOU 122117 WSWBOU URGENT - WINTER WEATHER MESSAGE National Weather Service Denver CO 217 PM MST Fri Mar 12 2021 ...POWERFUL WINTER STORM ON TRACK FOR THIS WEEKEND... .A significant late season winter storm will move from the Desert Southwest to near the Four Corners region by Saturday, and then track east/northeast across southeast Colorado Sunday. This track will bring significant snowfall to much of northeast and north central Colorado, and likely result in difficult if not impossible travel from late Saturday afternoon or evening through Sunday and Sunday night. The most severe conditions from deep accumulating snow will likely occur in and near the Front Range Mountains and Foothills where 2 to 4 feet of snow may fall, and along the I-25 Urban Corridor where up to 2 feet of snow can be expected. The favored locations for the heaviest snow totals along the I-25 Corridor will be from Boulder north through the Fort Collins area. Temperatures will be warm enough to bring a mix of rain and snow to areas east of a Fort Morgan to Limon line Saturday into Saturday evening, but temperatures should turn cold enough there Saturday night into Sunday for mostly snow. Winds are also expected to increase by Sunday, with blowing and drifting snow developing across the plains.
