A winter storm on the 26th, the day before Thanksgiving Day, dropped heavy snow over parts of Eastern Pennsylvania, caused power outages as well as additional traveling difficulties. Snowfall averaged 5 to 11 inches in the Poconos, 3 to 9 inches in Berks County and the Lehigh Valley and 1 to 4 inches in the Philadelphia suburbs. Generally less than an inch of snow and sleet fell in Philadelphia. The snowfall was also elevation dependent, with the highest accumulations occurring over the higher terrain in Berks County, the Lehigh Valley and Poconos.

Several municipalities, especially in the Lehigh Valley declared snow emergencies. As snow started to fall, a surge of accidents occurred, especially in the Philadelphia suburbs.
