Muggy night after strong thunderstorms sweep through DC area

A summerlike Tuesday gave way to strong and occasionally severe thunderstorms that rolled through the D.C. area from the west.

The storms caused temperatures to dip into the 60s and that is where it will hover all night

“That brings us close to the dew points, which are in the low end of the ‘muggy’ range, and that will make for an uncomfortable night. Some areas of fog will also form,” Storm Team4 meteorologist Matt Ritter said.

The National Weather Service had issued a severe thunderstorm watch for the entire D.C. area on Tuesday, which has since expired. Some the storms had the potential of producing damaging wind gusts and large hail, Ritter said.

A second line of rain, though not a severe storm, continued in southern Prince William and Stafford counties, in Virginia. Heading south on I-95 in Virginia “is just not going to be pleasant,” Ritter said.

Dave Dildine, in the WTOP Traffic Center, said the weather had an impact on traffic, with dark signals at intersections and downed trees on roads including Interstate 66.

A few showers will move in for the morning rush Wednesday, ahead of a strong cold front that will be moving through during the midday hours.

Even though it won’t be as warm Wednesday with limited sunshine, lots of low-level humidity and the strength of the front will mean a chance for some more gusty thunderstorms as the front moves through, followed by a rapid drying out Wednesday night.

It will be mostly sunny and seasonable on Thursday, followed by clouds and some showers with cooler temperatures on Friday.


Tuesday night: Scattered strong to severe thunderstorms; very warm and humid.
