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

Hot and dry conditions will make D.C.-area temperatures in the lower to mid-90s feel like they’re approaching 100 Monday afternoon. 7News First Alert Senior Meteorologist Brian van de Graaff said be prepared for what will feel like “a scorcher,” but humidity won’t be “overly oppressive.” He said Monday will be the only dry day of the week.

“Remember those heat safety tips which include staying hydrated and taking plenty of breaks in the shade if you have to be outside,” added 7News Meteorologist Mark Peña. A few clouds will begin moving through the D.C. region Monday night, with overnight temperatures falling into the 70s.



Tuesday’s temperatures and heat index are forecast to be similar to Monday’s in the 90s, but van de Graaff said the higher humidity will mean it may feel a little bit hotter. A cold front is due to push through the area by the afternoon, brining with it scattered, “strong to even severe” storms. Wednesday will be cooler and cloudy, before remnants from Tropical Storm Debby deliver rain and rumbles of thunder to the area. Those conditions, along with cooler temperatures, are expected to persist until the weekend. The National Weather Service said areas that will be most vulnerable to flash flooding are in north central and eastern Maryland including Baltimore, Halford and Cecil counties. Heavy winds up to 40 mph will also move through the area this week, according to the NWS.

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.
