 Tracking more heat and humidity in the threat for strong storms this afternoon. Before that, temperatures into the 90s. Heat index around 100 degrees once again any time after lunchtime. Then by 3 o'clock, we'll be switching gears over toward the storm tracking with the chance for strong to severe storms starting off over the higher terrain moving toward the D.C. metro later this afternoon. Should come to an end by midnight tonight. In fact, by sunset, most of the severe weather will be done. Just leftover showers.
