What happened
The episode as NWS PHI wrote it up.
A strong cold front moved through Eastern Pennsylvania during the late afternoon and early evening on the 8th. A strong secondary low formed on the frontal boundary overnight and by 8 a.m. EDT on the 9th was located near Worcester, Massachusetts. The intensifying low pressure system brought strong and gusty west to northwest winds into Eastern Pennsylvania from the early morning of the 9th into the early evening the same day. It also ingested enough cold air to change the rain over to snow before it ended across the region during the morning of the 9th. The changeover started in the Pocono Highlands of Monroe County around 1100 p.m. EDT on the 8th and slowly spread southeast. The rain changed to snow around 3 a.m. EDT in Stroudsburg. The sooner changeover permitted heavy snow to fall over the higher terrain in the county. Elsewhere the change to snow spread southeast from Monroe and Carbon Counties. Because the storm was relatively intense, the cold air wrapped around the south side of the system and the change from rain to snow across the southeast part of the state (between 3 a.m. and 5 a.m. EDT) occurred from the southwest to the northeast. The snow ended by noon. Accumulations in the Poconos ranged from 2.5 inches in the valleys to 10 inches on the hilltops. Accumulations elsewhere ranged between 1.5 and 5.0 inches. The slushy roadway conditions led to accidents, especially around the Philadelphia area. In Whitemarsh Township (Montgomery County), two people were killed after their vehicle skidded into a utility pole. There were five accidents on Interstate 95 around Philadelphia. The combination of the heavy wet snow and strong gusty winds downed trees, tree limbs and power lines, particularly in the Philadelphia suburbs. One downed tree crushed a moving car in Valley Forge National Park (Chester County), but the occupants were unharmed. In Doylestown, one of several downed trees damaged the chimney and roof of a house. About 40,000 PECO Energy customers lost power in the Philadelphia area. All but 200 had powered restored by the night of the 9th. In the Poconos, about 1,500 homes and businesses lost power, nearly two-thirds occurred in the Lake Naomi area of Tobyhanna Township (Monroe County). Accumulations included 10 inches in Tobyhanna (Monroe County), 5 inches in Wynnewood (Montgomery County) and Williams Township (Northampton County), 4.2 inches in Furlong (Bucks County), 4 inches in Glenmoore (Chester County) and Palm (Montgomery County), 3.7 inches at the Lehigh Valley International Airport, 3.3 inches in Downingtown (Chester County), 3 inches in Morgantown (Berks County), 2.5 inches in East Stroudsburg (Monroe County), 2.1 inches in West Chester (Chester County), 2 inches in Fricks (Bucks County) and Honey Brook (Chester County),1.6 inches at the Philadelphia International Airport and 1.5 inches in Perkasie (Bucks County) and the Franklin Institute within Philadelphia.Peak wind gusts included 51 mph at the Philadelphia International Airport, 48 mph at the Northeast Philadelphia Airport, 44 mph at the Wilkes-Barre/Scranton Airport and the Lehigh Valley International Airport and 43 mph in Doylestown (Bucks County) and Pottstown (Montgomery County).
