Snow showers are expected across the Rockies, rain and thunderstorms move into the Southern Plains, and the East dries out on Friday as multiple weather features affect the country. In the Southwest, a low pressure system moves eastward into the Southern Plains from the Desert Southwest on Friday. This system will continue pulling Pacific moisture eastward with it, producing scattered showers and thunderstorms from the Central and Southern Rockies through the Southern Plains. Some of these storms will turn severe with strong winds and large hail. This system has a history of producing wind gusts up to 30 mph, but gusts up to 50 mph are possible at high elevations of the Central and Southern Rockies. Also expect snow to develop at high elevations of Colorado, Utah, and northern New Mexico. Most of these areas will see 1 to 3 inches of snow, but highest elevations may see up to 8 inches of new snow. At the same time, a warm front will extend ahead of this system to the east, also kicking up scattered showers and thunderstorms through the Tennessee Valley.

To the north, a low pressure system in the Gulf of Alaska pushes a trough of low pressure and associated cold front into the Pacific Northwest. This will push abundant moisture onshore from the Pacific Ocean, triggering rain showers across western Oregon and Washington by Friday evening. Precipitation should remain as rain showers across most of the area.
