What happened
The episode as NWS LWX wrote it up.
A return flow around high pressure pumped in plenty of warm and moist air over the region. Colder air aloft associated with an upper-level trough combined with the warm and moist air at the surface to develop moderate amounts of instability. A surface trough acted as the lifting mechanism for showers and thunderstorms to develop during the afternoon and evening hours. Thunderstorms were able to produce damaging wind gusts.

THEREFORE AN EXPANSION OF THUNDERSTORMS FARTHER NORTH INTO THE LWX CWA THAN PREVIOUSLY EXPECTED IS NOW POSSIBLE. WHILE THE SATURDAY NIGHT ACTIVITY WILL BE PRIMARILY SOUTH OF DC...WHERE LIKELIES WERE ENTERED...HIGH CHANCE POPS WERE ADDED TO THE BALT-WASH METRO FOR LATE SATURDAY NIGHT. MCS ACTIVITY LOOKS LIKELY...THOUGH THE EFFECTS OF PASSING THE APPALACHIANS ARE ALWAYS A QUESTION. AT THIS TIME IT SEEMS LIKE THE ACTIVITY WOULD BE ABLE TO HOLD TOGETHER EAST OF THE MOUNTAINS.
