The sweltering temperatures from the three-day heat wave are starting to drop Saturday in the D.C. region with thunderstorms coming in. Here’s what you need to know.

The National Weather Service has issued a Severe Thunderstorm Warning for parts of Northern Virginia and Maryland until 4:30 p.m. with storms coming in from the Northwest.

Also, a Severe Thunderstorm Watch has been issued until 9 p.m. in the area. According to 7News meteorologist Mark Peña, strong storms will come in and bring the threat for gusty, damaging winds that may knock over trees and power lines.

A heat advisory is still in effect until 8 p.m. on Saturday, with residents urged by local leaders to stay cool and hydrated.

A cold front should swing into the region on Saturday night, finally offering relief from the heat. WTOP meteorologist Steve Prinzivalli says that northwesterly winds will bring cooler and less humid weather for the second half of the weekend.

“The weekend will start with more oppressive heat, humidity, and nasty thunderstorms before quieter and refreshing weather returns by Sunday,” Prinzivalli said.

Where to beat the heat and stay cool

D.C. is urging residents to stay cool and hydrated, check on older adults and other vulnerable neighbors, keep pets indoors and wear appropriate clothing and sunscreen.

The District has activated its Hot Weather Emergency through Sunday. D.C. spray parks and recreation centers have extended hours through Sunday, and cooling centers throughout the District will be available for those seeking relief from the heat.

Christopher Rodriguez, director of the District’s homeland security agency, said that Mayor Muriel Bowser’s declaration of a hot weather emergency this week allows the city to open cooling centers and other facilities so residents can beat the heat.

He urged residents to familiarize themselves with the symptoms of heat-related illnesses, and to avoid strenuous activities outdoors whenever possible. A list of the District’s cooling centers can be found online.

“Do not underestimate the impact that this heat emergency is going to have on you. I know there’s a lot of people out there who want to go out for their runs, or want to spend a lot of time outside,” Rodriguez said.

“Limit your time outdoors, and make sure you stay hydrated. Because you’re dealing with triple-digit temperatures and the potential for a heat index of up to 110 degrees, you can very quickly feel those impacts.”

Additionally, D.C. Public Schools have canceled all outdoor activities through Sunday.
