Could the DC area see a low-humidity, pleasant summer’s day on Thursday?

Listen live to WTOP for traffic and weather updates on the 8s.

After the D.C. area saw severe storms that left thousands in the dark on Wednesday night, the region could have lovely, low-humidity summer days on Thursday and Friday.

The cold front that swept over the region Wednesday brought serious thunderstorms that caused delays at all three major airports and put the area on severe storm watch until midnight. The storms also packed heavy downpours, something the D.C. region desperately needed after a series of hot and rainless days.



More than 10,000 Dominion Energy customers in Northern Virginia were left without power late Wednesday night around 11 p.m. That includes outages for about 2,000 combined customers in Loudoun, Fauquier and Prince William counties, and around 9,000 customers in Fairfax County.

A spokeswoman for Dominion Energy told WTOP that the outages are due to downed trees and downed power lines all across the area. Crews are out and expected to work through the night and to the end of the day Thursday to get power restored.

However, remnants from Wednesday’s storms are expected to slow down the work crews.

Thursday will have clear skies around 7 a.m. accompanied by some gusty winds and a drop in the humidity that has bogged down the D.C. area for the past week. 7News First Alert meteorologist Brian van de Graaff says the weather will be “rather refreshing.”

“We’re watching some drier air start to work its way in here today behind last night’s rain, so some good news there,” he said. “We’ll see the humidity dropping back, should be rather comfortable.”

Temperatures should stay in the upper 70s with highs in upper 80s, making it one the coolest day in almost two weeks. Friday will also offer a bit of respite from the hot and humid conditions lately.

“Friday looking fantastic: Mid-80s, sunshine, low humidity, it’s gonna be a great day!” van de Graaff said.

However, the humidity will return in full force over the weekend, along with scattered showers.

“Now the weekend will become steamy, looks like temperatures could be back in the low 90s but with high humidity,” van de Graaff said. “It’s going to be soupy, that could lead to a couple afternoon storms both days but still plenty of dry time.”

Hot, humid week ahead for DC area with severe storm risk

A dangerous heat wave will grip the D.C. area through Thursday, with highs in the mid to upper 90s and heat index values between 100 and 105. Hot and humid conditions are expected through Thursday, according to the National Weather Service, which said to expect daily thunderstorm chances and a risk of severe thunderstorms. 7News Meteorologist Eileen Whelan told WTOP that most of Tuesday will stay dry, but a few late-day thunderstorms are possible, especially north and east of D.C. as storms drift south from Pennsylvania. Any storm could produce damaging wind gusts and hail, but Whelan reiterated "storm chances are low" on Tuesday. Due to a lack of air conditioning, Parkdale High School in Riverdale, Maryland, closed early at 10:30 a.m. on Tuesday, Prince George's County Public Schools said in a social media post.
