A small craft advisory remained in effect on Friday through 2 a.m. on Saturday for the Chesapeake Bay from North Beach to Drum Point, Maryland and from Drum Point to Smith Point, according to the National Weather Service.

Looking ahead to Monday, the NWS said isolated severe thunderstorms are possible Monday afternoon and evening in the D.C. area.

The downpours on Friday could cause localized flooding in the DC-Baltimore region, according to the Washington Post's Capital Weather Gang. After more rain on Saturday, summer sunshine will take over on Sunday, with only a slight chance of showers, the Capital Weather Gang said.

WUSA9 forecasters are calling for a better chance of thunderstorms in the afternoon and evening on Friday.
