 Excessive heat warning moving through the early evening until 8 o'clock. Feels like temperatures fall from around 105 to the 90s as a line of strong to severe thunderstorms move across the DMV. Severe thunderstorm watch until 10 o'clock tonight. Some storms capable of producing gusty winds and heavy downpours. Once we get through all that, a few lingering showers overnight. A little bit cooler tomorrow, upper 80s to middle 90s. Chance for a few storms. We're only in the 80s on Friday. I'm 7 News meteorologist Steve Rudin in the First Alert Weather Center.
