The episode as NWS PHI wrote it up.
An unseasonably warm and humid airmass was over the Mid Atlantic region during the 19th. A strong area of low pressure moved into southeastern Canada during the afternoon, and a strong cold front associated with it approached and moved through the Mid Atlantic and Northeast in the evening. As a result, numerous showers and isolated thunderstorms developed. There was plenty of wind energy above the surface, therefore some of the isolated thunderstorms and even heavier showers produced strong wind gusts.
The local office's own words before the first event, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.
NWS Philadelphia/Mount Holly wrote its last area forecast discussion before the first event at Oct 19, 3:05 PM EST, 4 hours 53 minutes earlier.
