Damaging northwest winds followed along and a couple of hours after a strong cold frontal passage across the Lehigh Valley and the Poconos during the late morning of the 17th. Lower velocity, but still strong winds continued into the afternoon. Elsewhere across Eastern Pennsylvania strong wind gusts also accompanied the cold front and persisted into the afternoon. Peak wind gusts averaged between 45 mph and 55 mph. Numerous downed trees and wires were reported in the Lehigh Valley and the Poconos. Less widespread wind damage was reported elsewhere. In the Lehigh Valley, about 7,300 Pennsylvania Power and Light homes and businesses lost power. All power was restored by the morning of the 18th. In Berks County, about 4,000 homes and businesses lost power. All power was restored by 830 p.m. EST that evening. In Reading, a piece of a tin roof blew away from the rear of an apartment house and was suspended on utility poles on the adjacent street. Downed trees or wires closed roads in Cumru and Richmond Townships and Shillington Borough. In Montgomery County, a downed tree crushed a truck in Norristown. Peak wind gusts included 55 mph in Mount Pocono (Monroe County), 51 mph at the Lehigh Valley International Airport and Reading (Berks County), 49 mph at the Northeast Philadelphia Airport, 45 mph at the Philadelphia International Airport, 44 mph in Pottstown (Montgomery County) and 40 mph in Doylestown (Bucks County). The strong to high winds were caused by the pressure difference between an intensifying low pressure system that went northeast through the Saint Lawrence River Valley and a strong high pressure system that was building east from the Northern Plains.
