Severe thunderstorms and flash flooding will threaten areas from the South to the Ohio Valley through Tuesday night on the warm side of a winter storm tracking across the Midwest.
Severe storms initially fired up Monday night and early Tuesday and produced large hail across parts of North Texas.
FOX Weather Watcher Melisa LaPinta shared photos of golf-ball-sized hail in Frisco, Texas, about 3:30 a.m. Central time Tuesday morning.
The threat of severe storms Tuesday afternoon and evening will target parts of Middle Tennessee, northern Mississippi and northern Alabama.
Isolated tornadoes, damaging wind gusts and large hail are the main threats in this region.
