Snow fell across Eastern Pennsylvania mainly from the early morning through the late afternoon on the 3rd. Snowfall varied greatly across the area but in general a widespread 6.0 inches of snow was recorded, with the greatest amounts falling in the Lehigh and Delaware Valleys. The heavy, wet snow caused power outages and laid the foundation for the ice storm which followed in two days in the Philadelphia area.
The snow caused slippery traveling conditions on untreated and less traveled roadways.  In Berks County and the Philadelphia Metropolitan Area, precipitation started as rain around Midnight EST on the 3rd and changed over to snow between 3 a.m. EST and 7 a.m. EST that morning. Precipitation fell as snow throughout the event in the Poconos and Lehigh Valley and reached the area between 3 a.m. and 5 a.m. EST on the 3rd.  The heaviest snow fell during the daytime hours of the morning and ended in all areas between 4 p.m. and 6 p.m. EST that day.
Many municipalities declared snow emergencies. Approximately 60,000 PECO Energy customers lost power in the Philadelphia Metropolitan Area. Power was restored to all by the 4th. Many schools were closed and other events were postponed or cancelled. Speed reductions were in place on all of the major interstates. The snow caused 400 flight cancellations at the Philadelphia International Airport and on average four hour flight delays.  In the Lehigh Valley, LANTA suspended all commuter bus service. Tractor-trailers became stuck on hills. Airport Road was closed due a truck accident. The heavy snow caused awning collapses in Wilson Borough. The heavy snow caused suspension of trash and recycling collections and caused salt supplies to run low.
Representative snowfall amounts included 9.3 inches at the Lehigh Valley International Airport in Allentown (Lehigh County), 9.2 inches in Trappe (Montgomery County), 9.0 inches in Lower Heidelberg Township (Berks County) and Hilltown Township (Bucks County), 8.7 inches in Furlong (Bucks County), 8.5 inches in East Coventry Township (Chester County), Jenkintown (Montgomery County) and New Tripoli (Lehigh County), 8.2 inches in Wernersville (Berks County) and Spring City (Chester County), 7.8 inches in Saylorsburg (Monroe  County), 7.3 inches in Bowmanstown (Carbon County), 7.0 inches in Martins Creek (Northampton County), 6.4 inches in Chapman (Carbon County), 6.2 inches in Franklinville (Philadelphia County), 5.2 inches in Somerton (Philadelphia County), 4.5 inches in Drexel Hill and Norwood (both Delaware County),  3.8 inches in Pocono Summit (Monroe County) and 3.5 inches at the Philadelphia International Airport.
The heavy snow was caused by a low pressure system that formed on a cold front in eastern Texas on the morning of the 2nd. The low moved northeast and reach Mississippi on the evening of the 2nd, western North Carolina on the morning of the 3rd, the Delmarva coastal waters during the afternoon on the 3rd and then moved quickly offshore. As the precipitation intensity increased and colder air moved into the state, the rain changed to snow.
