[related_gallery align=”none”] As if record-breaking heat, torrential downpours and booming thunderstorms over the last several days isn’t enough, the weather Gods have more in store for the D.C. region to close out the week — a flash flood watch with the potential to bring pockets of 2 to 4 inches of rainfall an hour is in effect for the majority of the D.C. region Saturday night. A flash flood warning has been issued for a large portion of the WTOP listening area — including D.C.; Prince George’s County in Maryland; and Arlington, Fairfax, Prince William counties as well as Alexandria in Virginia — until 3:15 a.m. Sunday. Showers and thunderstorm are in the forecast as temperatures dip into the 60s in the suburbs and lower 70s in town overnight. The majority of the D.C. region is under a flash flood watch until 4 a.m. StormTeam4 Meteorologist Steve Prinzivalli cautions drivers to turn around and find an alternate route if they come upon a flooded roadway. “The main hazard with any thunderstorms will be very heavy rainfall,” Prinzivalli said. “Any thunderstorms that develop could contain heavy rainfall at the rate of two to four inches per hour, possibly leading to flash flooding. When you encounter a flooded road, turn around and find an alternate route.”

Damaging winds and frequent lightning are also a possibility, Storm Team4 Meteorologist Lauryn Ricketts said. Temperatures should stay in the 80s throughout the evening before cooling off overnight. Sunday will be cooler and drier. Northwesterly winds will start to dry out the area bringing in not just more seasonable temperatures, but also much more comfortable levels of humidity. But the cold front will stall nearby, so it will be considerably cloudy with the risk of a leftover shower or two.
