Moderate to heavy snow is likely Monday across the Central Rockies, Northern Plains, and Upper Great Lakes. Isolated strong to severe thunderstorms are possible along the Central Gulf Coast.
An area of low pressure will exit the Rockies and move eastward through the Northern Plains and toward the Upper Great Lakes. An additional 5-10 inches of snow will be possible across the high terrain of Colorado. Across the Northern Plains, light to moderate snow will be likely with 3-6 inches possible; some isolated areas may see up to 8 inches. Winds will allow for reduced visibilities and treacherous travel conditions.
A warm front over the Northern Gulf of Mexico will slowly lift northward and allow for the potential for a few isolated strong to severe thunderstorms across Louisiana and Mississippi. The main threats with any storms that develop will be moderate to heavy rain, lightning, small hail, and gusty winds.
