Be sure to have a way to receive severe and flood warnings this weekend, including overnight. A potent storm system will bring heavy rainfall and severe thunderstorms from Texas to West Virginia. This threat will be higher than seen on Wednesday night from Shreveport, Louisiana, to Cincinnati, Ohio and Roanoke, Virginia. Parts of the Tennessee Valley could receive up to 6 inches of rain as a squall line sweeps through the South Saturday into early Sunday. Several tornadoes and damaging winds are likely.
