Some outages persist as DC area expects another round of afternoon storms

Forecasters expect another round of wet weather after severe storms brought flash flood warnings and widespread power outages to D.C. and its Maryland and Virginia suburbs. Here’s what you need to know.

WTOP Meteorologist Briana Bermensolo said Sunday’s weathered will likely include another chance for storms with “pockets of steady rainfall.” Those rains could bring about another wave of watches for the area.

“Heavy downpours and storms will continue throughout the afternoon and early evening hours,” Bermensolo said. “… Storms will be the theme of this weekend as another round of heavy downpours, high wind and lightning — all possible for Sunday afternoon.”

The National Weather Service expects new rainfall amounts to be anywhere from a tenth to a quarter of an inch, though higher amounts may be possible in thunderstorms.

Muggy conditions persist tonight, with temps generally in the 60s to around 70F. Some showers and storms could redevelop overnight. Otherwise, patchy fog is likely to develop, especially west of the Blue Ridge where dense fog is possible. #VAwx #MDwx #WVwx #DCwx pic.twitter.com/yIPygAZCHn

“The threat for isolated flooding will continue Sunday with deeper and widespread moisture spreading across the area as a weak wave of low pressure tracks along the stalled front,” the National Weather Service said in its forecast. “A few embedded thunderstorms are also possible on Sunday, but the severe threat looks to drop with increased cloud cover and cooler temperatures across the region.”

While afternoon storms remain possible through the start of the workweek, Bermensolo expects temperatures to look much less like our record-breaking heat after Wednesday afternoon.

“[The] 70s stick around with much calmer weather by Thursday and Friday, sunshine to finish the week and a taste of fall continuing through Friday,” Bermensolo said.
