While a massive winter storm plunges much of the country into a deep freeze of ice and snow, the same system threatens the Deep South with a new hazard — severe thunderstorms. A line of thunderstorms is expected to organize Sunday morning across Louisiana and Mississippi, just south of the icing zone, before pushing into Alabama and the Florida Panhandle around midday. By late afternoon, the severe threat will shift into southwest Georgia.
