The dangerous outbreak will continue to sweep through the South and East through the weekend. Saturday could be one of the worst severe weather days of the year.

A powerful low-pressure system is likely to spawn a dangerous outbreak of severe thunderstorms in portions of the Midwest, South and East, where tornadoes, widespread damaging winds, large hail and flash flooding are all concerns.

A multiday severe weather outbreak across the eastern U.S. continues Saturday, with the risk of a tornado outbreak even higher than it was Friday.
