In the higher elevations of Wyoming, the Front Range, and the Wasatch, heavy wet snow will continue but should ease off by tonight. Lastly, the eastern U.S. is in for an early heatwave, with temperatures potentially breaking records, especially in the Mid-Atlantic and New England.

By evening, the threat shifts south into the Southern Plains, with severe thunderstorms likely to impact Texas and the Lower Mississippi Valley late Tuesday.

Heavy Snow Across the Rockies

The mountains in Wyoming, the Front Range, and the Wasatch are blanketed in heavy, wet snow today. This is due to the storm system moving through the area, bringing colder air. Expect this snowfall to taper off by tonight.

Fire Weather Concerns in the Southern High Plains
