D.C. area residents and July Fourth visitors are enduring a third day of searing heat, this time with the possibility of afternoon and evening thunderstorms that are expected to pack a punch.

“The (National Weather Service) Storm Prediction Center has put the immediate metro area under an enhanced risk of severe thunderstorms this afternoon,” 海角社区app meteorologist Mike Stinneford said. “Thunderstorms with gusts of 70 to 80 mph are possible. The time frame for the worst of the storms is 3 p.m. to 9 p.m.”

The storms could add a new challenge to holiday festivities, several of which have already been changed or canceled due to the oppressive and dangerous heat.聽

Thunderstorms could bring flooding downpours, hail and damaging wind gusts, AccuWeather said.

The National Weather Service also has the region under an between 10 a.m. and 9 p.m., with highs expected to break the Fourth of July record of 100 degrees in 1919. High humidity is expected to send heat index values as high as 112.

Soaring triple-digit temperatures also broke records over the previous two days.

Evening storms and wind are not expected to provide much relief from the heat and humidity. Sunday’s highs are in the high 90s, and more severe storms are predicted.聽
