A southerly flow preceding a powerful cold front produced high winds during the afternoon in most of Eastern Pennsylvania. The westerly flow behind the front during the evening produced strong winds throughout the region. Measured peak wind gusts averaged near 50 mph with higher gusts estimated during the high wind events. The wind damage was exacerbated by a line of strong to severe thunderstorms that moved through around 6 p.m. EST. Winds were from the south preceding the front during the afternoon and from the west behind the front during the evening.
A few people were injured in Horsham Township (Montgomery County) when the top three layers of a partially constructed concrete wall collapsed. The high winds tore part of a roof from a small hanger at the Lehigh Valley International Airport. Part of the roof landed on power lines. The high winds also knocked over a traffic light in Allentown (Lehigh County). The high and strong winds knocked down trees, tree limbs and power lines. Tree limbs and holiday decorations became flying debris. Several planned holiday lighting festivities and football games were postponed. The combination of the high winds and thunderstorms caused about 65,500 of Pennsylvania, Power and Light's eastern Pennsylvania to lose power. All power was fully restored on the 3rd.
Measured wind gusts included 55 mph at the Northeast Philadelphia Airport, 51 mph at the Lehigh Valley International Airport, 48 mph in Mount Pocono (Monroe County,47 mph in London Grove (Chester County), 46 mph in Reading (Berks County) and 45 mph at the Philadelphia International Airport.
