A cluster of severe thunderstorms moved through the D.C. area intensified to severe status, according to the National Weather Service, leading to severe thunderstorm warnings and watches in the D.C. area.

The National Weather Service issued a severe thunderstorm watch for most of the D.C. area through 7 p.m. Thursday. A cold front moving across the area brought passing storms. Isolated severe storms had the potential to bring large hail and damaging winds in excess of 60 mph, though News4 meteorologist Veronica Johnson hasn't seen winds stronger than 40 mph.

People in the area were warned to prepare for the possibility of more power outages. Thursday morning, Pepco reported 7,800 customers still without power after Sunday's storm. That increased to 21,295. At about 4:30 p.m., Pepco reported 18,275 customers without power.

Metro reported at about 2:20 p.m. that the Friendship Heights station was closed due to a power outage. Trains were able to move through the station but weren't stopping. Shuttle bus service was established for riders who use the station. The station reopened at about 3:30 p.m.

There was plenty of lightning, and though isolated tornadoes were considered possible according to the National Weather Service, none has been reported.

A severe thunderstorm warning for east central Howard County, north central Anne Arundel County, Baltimore County and Baltimore expired at 4:45 p.m.

Earlier, a severe thunderstorm warning was issued until 2 p.m. for south central Carroll County, northeastern Howard County, northern Anne Arundel County and Baltimore County and city in Maryland. Another warning was issued until 2 p.m. for D.C.; southeastern Montgomery County, southwestern Anne Arundel County and Prince George's County in Maryland; and Alexandria, Falls Church, Arlington County and northeastern Fairfax County in Virginia.

A warning for southeastern Frederick County, northwestern Howard County and Montgomery County in Maryland and northeastern Loudoun County and north central Fairfax County in Virginia expired at 1:15 p.m.

In Baltimore, a flash flood warning was issued until 3:30 p.m., then another was issued after 4 p.m. until 6 p.m.

With the storms, the cold front brought cooler weather to the region. Temperatures dropped about 10 degrees. Expect highs in the mid-80s with low humidity both Friday and Saturday.
