Temperatures will drop sharply, and result in winter precipitation and possible hazardous travel conditions. Snow will first start in the northern mountains and northern border area late this evening, and then spread southward to the I-70 Corridor and rest of the plains overnight. Precipitation may begin as light drizzle and freezing drizzle on the plains, before switching over to all snow by Thursday morning. The Thursday morning commute looks snowy in most areas. Snow may accumulate on road surfaces even in lower elevations, with bridges and overpasses most susceptible to icing. Please allow extra time to travel in the season's first snowfall.
