The episode as NWS LWX wrote it up.
A cold front passed through northern Virginia, bringing showers and thunderstorms with it. A warm and humid air mass ahead of the front resulted in moderate amounts of instability. The instability combined with the cold front for a few thunderstorms to produce damaging winds.

REMAIN NORTH OF THE MASON- DIXON LINE...DEEP-LAYER SHEAR PROFILES
WILL INCREASE TO 45-55 KT AS THE FRONT APPROACHES...SUPPORTING
ORGANIZED STRONG CONVECTION. THE SETUP LOOKS FAVORABLE FOR
SCATTERED TO POSSIBLY NUMEROUS STRAIGHT-LINE WIND DAMAGE ACROSS
PORTIONS OF THE AREA...ESPECIALLY TOWARD THE WRN SHORE OF THE BAY.
THE STRONGEST UPDRAFTS MAY PRODUCE LARGE HAIL EAST OF THE BLUE
