A winter storm will impact eastern Utah and western Colorado from this evening through Tuesday morning. This system has the potential to generate 10 to 18 inches of new snow over Colorado's western mountains, and from 8 to 14 inches of snow over the eastern Uinta Mountains of northeast Utah. The Roan, Tavaputs, and Uncompahgre Plateaus and the La Sal and Abajo Mountains are more likely to experience 6 to 12 inch accumulations with locally higher amounts. Ahead of the cold front associated with this system, strong and gusty southwest winds from 20 to 30 mph with gusts of 40 to 50 mph will spread from southeast Utah to northwest Colorado this afternoon. Once the storm is through, expect markedly colder temperatures on Tuesday with highs falling shy of seasonal norms by 10 to 15 degrees. Winter Storm Watches are in place for several mountain sites from Sunday evening through Tuesday morning. Stay tuned for updates on this developing winter storm.
