A stormy weekend is in the works for much of the Deep South, with the National Weather Service predicting severe thunderstorms, damaging winds and possible tornadoes.

“The main hazards with these storms will be frequent lightning, severe thunderstorm wind gusts, hail, and a few tornadoes,” the NWS said Friday morning. There is an enhanced risk of severe thunderstorms over the Lower Mississippi Valley and Southern Plains on Friday, and a slight risk of heavy rain over parts of the same region.

“Low pressure over the Southern Plains will move eastward to off the Mid-Atlantic Coast by Sunday,” the NWS said. “The system will produce severe thunderstorms and heavy rain from the Southern Plains to the Southeast/southern Mid-Atlantic.”

The NWS’ storm prediction center has issued “an enhanced risk” of severe thunderstorms over parts of the Lower Mississippi Valley and Southern Plains on Friday into Saturday morning.

“There is an added risk of two-inch or larger hail over parts of central Texas and Oklahoma,” it said.

Thunderstorms are expected to produce heavy rain with scattered flash flood areas possible.

A second front over the Upper Midwest will move eastward to the Lower Great Lakes by Sunday. The system will produce rain over parts of the Upper Mississippi Valley and Upper Great Lakes into parts of the Ohio Valley, Mid-Atlantic and the Northeast through Sunday.

The storm will also produce light snow over parts of the Upper Mississippi Valley and the Upper Great Lakes from Friday evening into Sunday morning.
