Rain Soaks the South

Expect moderate to heavy rainfall along the Gulf Coast Thursday into Friday, with thunderstorms and a risk of flash flooding. The system will move east, bringing rain to the Southeast and wintry conditions further north into the Appalachians and Mid-Atlantic, with 1-2 inches of snow and possible ice glazing.

Brace for the Cold Blast

Across the Midwest, prepare for a surge of arctic air bringing record-challenging low temperatures Thursday morning.
