As the storm system responsible for bringing severe weather to the Central states at midweek continues to move eastward, the threat of severe weather will slowly diminish. However, a few storms along an advancing cold front can still bring strong gusty winds, hail and blinding downpours into Friday evening.
The greatest risk of thunderstorms with damaging wind into Friday evening is from eastern Ohio to northern West Virginia, western Pennsylvania and western upstate New York and over the Florida Panhandle, as well as in offshore Gulf of Mexico waters.
Winds in some of the storms can bring gusts to 60 mph. A couple of the strongest storms can produce a brief tornado.
Throughout the zone from the lower Great Lakes to the central Gulf Coast there can be brief downpours with incidents of flash, urban and small stream flooding possible.
People are urged to keep an eye on the weather for rapidly changing weather conditions. Listen to alerts on radio and TV. Stay up-to-date with devices equipped with AccuWeather Apps.
