Scorching temps, storms forecast during DC area’s latest heat wave

A mix of intense heat and thunderstorms are giving D.C. area residents both ends of the summer weather spectrum to cap off their weekend.

The weather pattern featuring high humidity and temperatures regularly in the 90s will carry until Wednesday. NBC Washington meteorologist Brianna Bermensolo said that in many areas, it will feel as if it’s over 100 degrees on Sunday due to heat indexes in the triple digits.

Sunday evening storms are in the forecast as well, with Bermensolo saying they could develop north of Interstate 66 and spread south later in the night.



Cooling centers in the District will remain open until July 28 for those who need them.

D.C. activates its Heat Emergency Plan whenever heat indexes exceed 95 degrees. You can find the nearest cooling center to you by checking out this interactive map.

Homeless residents can call a ride to the closest shelter by dialing 311 or the Shelter Hotline at 202-399-7093.

Monday’s weather will follow a similar track to Sunday’s — a hot and muggy start with storm chances increasing by the afternoon. Tuesday is expected to be dry, though storm chances return Wednesday afternoon before the heat finally starts to subside for the weekend.


Forecast:

Sunday night: Widely scattered thunderstorms, ending before midnight. Partly to mostly cloudy and muggy overnight. Lows upper 60s to mid 70s.

Monday: Partly sunny, hot and humid with a risk of afternoon thunderstorms, mainly south. Highs in the low to mid 90s.

Tuesday: Mostly sunny and hot, but a bit less humid. Highs in the mid 90s.

Wednesday and Thursday: Partly sunny, hot and humid. A chance of late day thunderstorms. Highs in the low to mid 90s.

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.
