As rising temperatures again prompt heat alerts this afternoon (see above), a front will increase thunderstorm activity through Wednesday evening.
Multiple record highs fell on Tuesday, and while a cold front improved conditions in some of these areas, the heat and humidity will persist for others.
Showers and thunderstorms will remain possible from Texas through Georgia over the next couple of days, as the cold front stalls out and becomes stationary. With the amount of heat and moisture in the atmosphere, storms could become severe at times.
Through Wednesday evening, the Storm Prediction Center has highlighted an area from Del Rio, TX, to Chattanooga, TN for the potential of isolated severe thunderstorms. Although there is no highlighted severe risk as of yet for Thursday, a new one could be added in future updates.
