 It'll be heavy for some spots today, but it will be on and off throughout the afternoon. And into tonight, so breaks in the rain, but some heavy showers and rumbles of thunder expected. Not expecting severe weather, that's the good news, but still some flooding concerns south and east of I-95 with a flood watch down towards St. Mary's County. That's where it's raining now. Leonardtown, some lightning and thunder. Get ready, Charles, and southern Prince George's County. Rain within the next hour. At least temperatures today, they will stay down. Low 80s for highs in the heat index, only around 82.
