Locally severe storms that erupt on Thursday are likely to hold off until late in the day or at night. Areas extending from the southern Appalachians to the central Gulf coast are at risk for severe weather, according to AccuWeather Senior Storm Warning Meteorologist Eddie Walker. The main threats from these storms in addition to flooding downpours are likely to be strong wind gusts and hail. As a disturbance in the jet stream pivots southeastward from the Rockies to the Plains on Friday, more robust storms are possible.
