SOUTHEAST - It's been muggy and stormy in the southeast and as we wrap up the holiday-long weekend, that trend will continue. Forecast highs and heat index values through Monday will likely reach the triple digits all across the southeast. Cities like Charleston, SC, will be feeling like 110 through Monday.
This heat and humidity will also help to drive diurnal thunderstorms (storms that are driven by daytime heating). There is a marginal risk across the southeast for severe weather through Monday morning but as we head into the day on Monday thunderstorms will continue to pop through the southeastern U.S.
