What happened

The episode as NWS PHI wrote it up.

Strong winds associated with a gust front from a line of thunderstorms farther to the west uprooted the metal stakes holding a tent in place at the Church of the Holy Eucharist in Tabernacle. The tent ripped in half and knocked over a few tables. Wind gusts in the county were averaging around 40 mph. Farther to the west in Westampton Township, lightning struck the 300 foot communications tower used by the Burlington County Central Communications. The bolt fried several antennas and prevented officials from contacting local fire companies.

What forecasters said that day

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 Aug 10, 2:40 PM EST, 5 minutes earlier.

INSERT A CHANCE FOR AFTERNOON SHOWERS AND TSTMS ON THURSDAY...AS A
