402 WWUS45 KBOU 120957 WSWBOU URGENT - WINTER WEATHER MESSAGE National Weather Service Denver CO 257 AM MST Mon Dec 12 2022 ...POTENT WINTER STORM HEADED FOR THE REGION... .A strong winter storm system will track toward southeast Colorado tonight, and then lift northeast into Nebraska by Tuesday. This track means that significant winter travel impacts can be expected especially over portions of the northeast plains of Colorado into the Nebraska Panhandle and parts of eastern Wyoming. Blizzard conditions will likely develop over northeastern Colorado as the storm intensifies late tonight and Tuesday morning. Strong winds are expected to gust to 50-60 mph, creating blizzard conditions. There is still some uncertainty about snow amounts, but the heaviest snow should be on the plains east of Greeley and Denver, focusing toward the Akron, Sterling, and possibly Fort Morgan areas. People planning travel north or east of Denver Tuesday, or those with outdoor livestock interests should prepare for likely blizzard conditions on Tuesday and continued cold and windy weather behind the storm Wednesday and Thursday.
