A Pacific storm off the southern California coast will move ashore Wednesday evening before tracking eastward across southern Nevada, southern Utah and onto the Four Corners region by Thursday morning. Though the arrival of the storm's center is a ways out, its impacts will be felt as early as Wednesday morning across southeast Utah and southwest Colorado as isolated to scattered light showers develop. A wintry mix of weather will spread north and eastward across the region as Wednesday progresses with the best chances for precipitation coming Wednesday night into Thursday morning as the storm moves to the Four Corners region. The latest model output suggests snowfall amounts of up to one foot are possible over portions of the San Juan Mountains and up to 8 inches across the La Sal, Abajo Mountains of southeast Utah and portions of the Uncompahgre Plateau and Grand Mesa in western Colorado. Conditions improve later on Thursday as the storm shifts to the southern Plains during the afternoon.
