Heavy rainfall and possible flooding for DC and the region

Washington, D.C., and the surrounding area is expected to see some thunderstorms roll through Sunday night, bringing the possibility of flooding in certain areas. Here’s what you need to know.

Scattered showers and thunderstorms are likely this evening, then a chance of showers after midnight. Some thunderstorms may produce gusty winds, small hail, and heavy rainfall.

The area is extremely humid, and thunderstorms have already returned to areas west, bringing some gusty winds, significant rainfall and small, penny sized hail.

While the District and immediate suburbs were spared some of the downpour and flooding we saw on Saturday, areas west experienced heavy rain and winds, leading to some localized flooding and fallen debris blocking roadways.



Storm Team4 meteorologist Lauryn Ricketts said flooding may once again be possible Sunday evening.

“We have showers and thunderstorms developing this afternoon. Damaging winds and of course heavy rain, given the humidity, are going to be a possibility. We’ll have to watch for flooding,” Ricketts said.

Temperatures were mostly in the mid to upper 80s Sunday afternoon, and are expected to drop into the 60s and 70s come nightfall.

Rainfall is expected to move through overnight, drying up just in time for the Monday morning commute.

Monday is expected to start off partly cloudy, with temperatures shooting up to 90 degrees. Expect showers and thunderstorms to develop after 2 p.m. as a cold front pushes into the region.

Some of the storms could be strong to severe, and there’s the chance for a tornado to touch down Monday, Ricketts said.

By Tuesday, the area should dry out with plenty of sunshine and temperatures around 90 degrees. It will continue to be incredibly humid, so the heat index will be in the mid-90s.

Later on in the week, the concern will be increased heat, with heat indices breaking 100! Remember to stay hydrated, dress light and take frequent breaks.

A chance for rain returns Thursday as a cold front could approaches the area. Temperatures top out the mid to upper 90s by Thursday.
