Storm Threat Lingers Thursday After Tornadoes, Flooding Slam MD

MARYLAND — A severe thunderstorm watch remains in effect for several Maryland counties Thursday, a day after storms spawned multiple tornadoes and inundated parts of the state with flash flooding.

According to the National Weather Service, the watch is in effect until 9 p.m. Thursday for the following counties: Anne Arundel, Baltimore, Calvert, Caroline, Cecil, Charles, Dorchester, Harford, Howard, Kent, Montgomery, Prince George's, Queen Anne's, Somerset, St. Mary's, Talbot, Wicomico and Worcester.

In its latest forecast, the NWS said a cold front over the Ohio Valley was expected to move into the state Thursday, bringing another round of showers and thunderstorms to the region by this evening.

Storms will be capable of producing up to 65 mph wind gusts. Heavy downpours, hail and lightning are also possible, forecasters said.

Thursday's storms come less than a day after another system spawned several tornadoes in Baltimore, Howard and Montgomery counties. Structures were damaged in Gaithersburg, with emergency crews dispatched to help people trapped inside.

In Harford County, 10 people were rescued from their cars after a torrential downpour prompted flash flooding in parts of the state.

While storms could be strong Thursday, a repeat of Wednesday is not likely, according to the Capital Weather Gang's latest forecast.

"Isolated wind damage is the main severe weather threat, primarily east of Interstate 95," the Capital Weather Gang said. "For areas west of Interstate 95, most of the storms should occur before 6 p.m. East of I-95, they’ll be most probable between about 5 and 9 p.m."

On Thursday afternoon, a tornado warning was briefly issued for northern Montgomery and southeastern Frederick counties; however, the National Weather Service canceled the warning as storm rotation weakened.
