Particularly hazardous thunderstorms are possible Tuesday for the Northern Plains. Marginally hazardous thunderstorms are possible for the Southeast.

Northern Plains/Great Plains:A shortwave trough over the Rockies will lift across the Northern Plains by Tuesday with what looks to be a more substantial risk for severe weather. Increasing moisture across the Great Plains will contribute to moderate instability from the Dakotas southward into the Southern Plains. This combined with more than sufficient deep-layer shear should support severe thunderstorms capable of all severe facets, and possibly a greater risk for tornadoes.

Southeast:Meanwhile, a weak upper-low will linger over the Southeast region with marginally severe impacts possible from Georgia into the Carolinas.
