A low pressure system that moved off the Virginia coast helped spread snow across Eastern Pennsylvania on the 8th. The snow lasted overnight on the 8th in the Poconos. Snowfall averaged 1 to 3 inches with the least amounts in the Lehigh Valley. Snow began on the 8th across southeast Pennsylvania between 6 a.m. EST and 9 a.m. EST and in the Lehigh Valley and the Poconos between 9 a.m. EST and 1030 a.m. EST. Snow ended during the middle of the afternoon on the 8th, except in the Poconos where snow showers persisted overnight. Untreated roadways were treacherous, especially during the morning and again at night in the Poconos.
Representative snowfall included 2.9 inches in Clifton Heights (Delaware County), 2.7 inches in Tobyhanna (Monroe County), 2.2 inches in Morrisville (Bucks County) and Pottstown (Montgomery County), 2.0 inches in East Nantmeal (Chester County) and Bensalem (Bucks County), 1.9 inches at the Philadelphia International Airport, 1.7 inches in Drexel Hill (Delaware County), 1.5 inches in Trappe (Montgomery County), 1.0 inch in Reading (Berks County) and Martins Creek (Northampton County) and 0.6 inches at the Lehigh Valley International Airport. The snow was caused by a low pressure system that moved southeast from the Ohio Valley on the evening of the 7th, across the Carolinas overnight on the 7th and then turned to the northeast. The low passed just east of Virginia Beach, Virginia at 4 a.m. EST on the 8th, moved northeast and was just east of the Delaware coast at 1 p.m. EST on the 8th. It started merging with another low that was moving across Pennsylvania. The merged lows intensified rapidly, but also started to accelerate and by 7 p.m. EST on the 8th, the single low was already south of Cape Cod, Massachusetts.
