The storm system which brought severe weather to the Northern Plains on Friday will now bring the risk for severe weather to the south and east.
On Saturday, severe storms will be possible across parts of the Ozarks and the Lower and Mid Mississippi River Valleys. Lines of showers and thunderstorms will develop this afternoon and will persist through the first half of the overnight. These storms will pose the main risk for large hail and damaging winds, but a few isolated tornadoes cannot be ruled out. Also portions of the Southeast will be at risk for severe thunderstorms with similar risks. Scattered storms will develop in the afternoon, and some of those may turn severe across portions of the eastern Gulf Coast through the Lowcountry of South Carolina.
Then on Sunday, as the cold front pushes farther to the south and east, isolated severe thunderstorms will be possible across portions of the Southeast and central Gulf Coast. Scattered thunderstorms are expected to develop during the afternoon and evening in this region. Also in much of New Mexico, a few strong to severe thunderstorms may develop. As a shortwave ejects into the Southwest, that added boost to the atmosphere may lead to the formation of thunderstorms late in the day across the area.
