Temperatures are set to drop to the low 70s overnight.
Prince William County police said cars were flooded in the parking lot of Jiffy Lube Live, where a Dave Matthews concert started later than scheduled due to bad weather. Firefighters checked about 20 to 30 vehicles that were flooded to make sure there were no people trapped inside.
There were no rescues, but some concertgoers may have lost their cars. Vehicles with yellow caution tape remained in the lot on Monday.
One woman, who was able to drive her car home eventually, gave her information to a Jiffy Lube Live employee but didn't hear back from the venue right away.
A huge tree toppled onto Donald Berkheimer's beloved 1983 Buick Electra outside his home in Wheaton, Maryland, earlier Saturday.
"Life is like a receding fall. You never know what the next hour is going to bring," Berkheimer said.
Radar showed heavy rain falling across the area and about an inch fell in northern D.C. and parts of Prince George's County, the National Weather Service said at 6:15 p.m.
