Storms roll through with most of DC region under Severe Thunderstorm Watch

A string of extremely hot September weather gave way to scattered severe storms Thursday, leaving most of the D.C. region under a Severe Thunderstorm Watch until 9 p.m. Thursday. Here’s what you need to know.

Warnings have been popping up and ending quickly as sporadic storms sweep through the area. Early Thursday evening, the National Weather Service said a strong storm near the American Legion Bridge was moving northeast at 30 mph with potential 60-mph wind gusts and quarter-size hail.

WTOP meteorologist Howard Bernstein said the passing storms mostly entailed “very heavy rain and potential for 60 mph gusts and hail up to an inch in diameter” as they moved northeast through the area.

On Thursday afternoon, bands of strong storms rolled through parts of Northern Virginia and suburban Maryland, bringing heavy winds and hail, and triggering warnings from the weather service.

One storm system, which earlier dumped two inches of rain in some areas and downed some trees in Virginia, has mostly moved north to Pennsylvania. However, additional storms are still making their way through the D.C. area.

Though temperatures did climb into the 90s again on Thursday, temperatures in some areas dropped into the 70s as storm clouds rolled in.

“So these 20 degree temperature drops are happening quite rapidly in a few locations with some of the storms passing through,” said 7News First Alert Chief Meteorologist Veronica Johnson.

Current weather

Thursday marked the fifth day of a historic September heat wave, but highs around the area were a degree or two lower than the sizzling days earlier this week, said 7News First Alert meteorologist Eileen Whelan.

Daily record highs were broken at all three D.C.-area airports on Wednesday.

Dulles International Airport reached 100 degrees — the first time ever in the month of September that it has reached triple digits since the National Weather Service started recording temperatures at the airport back in the 1960s.

Temperatures at BWI Marshall and Reagan National airports broke the daily record with a tie at 98 degrees.
