StormTeam4 meteorologist Somara Theodore said the mix of sunshine and clouds have helped to destabilize the area’s weather, and could cause some severe storms heading into the evening.
“Heavy rainfall in short periods of time may cause creeks and streams to rapidly rise out of their banks along with the potential for flash flooding in urban areas,” warns the National Weather Service. “You should monitor later forecasts and be prepared to take action should flash flood warnings be issued.”
A low pressure center will move through the D.C. region, making for a rainy Saturday night and Sunday morning.
Sunday: Cloudy and cool with periods of rain and drizzle. Highs in the mid-60s.
Monday: Partly sunny. Highs in the mid-70s.
Tuesday: Sunny. Highs around 80s.
