The D.C. region was hit with another round of showers and thunderstorms Wednesday morning and a few isolated showers could pop up in the evening hours.
Things should dry up after sunset but the humidity isn’t going anywhere, according to 7News First Alert Meteorologist Mark Peña.
An earlier flood watch from the National Weather Service has expired in Anne Arundel County, Maryland.
There’s been a mix of clouds and sun, with temperatures in the upper 80s.
Peña said a warm front will usher in a big surge of tropical moisture overnight. Heat index values will be closer to 100 degrees during the afternoon Thursday.
“Remember to stay hydrated. Take plenty of breaks in the shade if you happen to be outside, as well as wear light-colored, loose-fitting clothing,” Peña said.
The heat and humidity will continue for the next several days, with chances of a few isolated, scattered showers and storms each afternoon.
The rainfall could produce heavy downpours, which may cause localized flooding on low-lying roads and in areas with poor drainage.
“If you come across any water over the roads, turn around, don’t drown,” Peña said. “And although the severe threat is rather low, thunderstorms are capable of producing some gusty winds, frequent lightning, and, of course, some briefly torrential blinding rainfall.”
Thursday will be partly cloudy and hotter, with highs in the upper 80s to lower 90s. Isolated showers and thunderstorms are possible by the evening as the stalled weather system begins moving offshore. This shift could also increase the risk for severe storms.
Friday will bring another hot and humid day, with highs between 90 and 95 degrees. Pop-up afternoon thunderstorms are again possible, with some capable of producing heavy rain, frequent lightning and gusty winds.

A front will remain stalled across the area for the next several days, and there will be a chance of rain and severe storms into the weekend.
