A low pressure system emerged east off the North Carolina coast and spread snow across eastern Pennsylvania, with some heavy snow occurring in and around the Philadelphia metropolitan area from the evening of the 16th into the morning of the 17th. Snowfall totals ranged mainly from 4 to a little over 5 inches around the Philadelphia metropolitan area, with mainly less than 4 inches occurring elsewhere across eastern Pennsylvania.
The snow caused accidents and impacted the morning commute on the 17th. In fact, SEPTA suspended several bus routes during this winter storm in southeastern Pennsylvania. In addition speed reductions were in place on nearly all major interstates and highways in Eastern Pennsylvania. About 120 flights in and out of Philadelphia International Airport were cancelled. Schools in the Philadelphia Metropolitan Area and Berks County were either closed or had two hour delayed openings.
Representative snowfall totals included 5.6 inches in Bala Cynwyd (Montgomery County), 5.5 inches in Levittown (Bucks County) and in Lower Makefield Township (Bucks County) and in Feasterville (Bucks County) and in Langhorne (Bucks County) and also in Wyndmoor (Philadelphia County), 5.2 inches in Bryn Mawr (Montgomery County), 5.1 inches in Drexel Hill (Delaware County), 5.0 inches in Morrisville (Bucks County) and in Bensalem (Bucks County) and in Ridley Park (Delaware County) and in Wynnewood (Montgomery County) and in Fox Chase (Philadelphia County) and also in Rockledge (Philadelphia County), 4.8 inches in Kennett Square (Chester County), 4.5 inches in Chadds Ford (Delaware County) and in Montgomeryville (Montgomery County) and in Port Richmond (Philadelphia County), 4.0 inches in Malvern (Chester County) and in East Goshen Township (Chester County) and in Bustleton (Philadelphia County) and in Hatfield (Montgomery County) and in North Wales (Montgomery County) and also in Harleysville (Montgomery County), 3.7 inches at the Philadelphia International Airport (Philadelphia County), and 2.4 inches at the Lehigh Valley International Airport (Lehigh County).
The snow was caused by a low pressure system that organized over the Southern Plains on the evening of the 15th. It moved east-northeast across the Gulf Coast States during the day and evening of the 16th, before tracking more northeastward and passing east of Cape Hatteras, North Carolina by 4 a.m. EST on the 17th. The low pressure system then raced northeast and out to sea during the daytime. The relatively southeast track and rather fast movement of this system prevented heavier snow from spreading much beyond the greater Philadelphia area.
