What happened

The episode as NWS PHI wrote it up.

For the second time in the day, strong gusty winds spread across Eastern Pennsylvania. This was triggered by an upper air disturbance that helped develop showers. These showers subsequently mixed down some of the stronger winds aloft to the ground. Peak wind gusts with this second wave were slightly lower than the winds that accompanied the initial cold frontal passage and averaged between 40 and 45 mph. The winds were strong enough to knock over one tree in Upper Darby Township. PECO Energy reported about 21,000 homes and businesses lost power in Southeast Pennsylvania from both the cold frontal passage and the second wave of strong gusty winds. Peak wind gusts with the second wave included 44 mph at the Lehigh Valley International Airport and 40 mph at the Philadelphia International Airport.
