Strengthening surface low pressure south of the region, advancing eastward from Kentucky to the North Carolina coast, coupled with an upper air disturbance moving overhead produced accumulating snow across portions of eastern Pennsylvania during the day on the 15th.  Snowfall totals ranged from 6 inches across the higher elevations in Carbon and Monroe Counties to between 1 and 4 inches southward into the Lehigh Valley, Berks County, and the western Philadelphia suburbs, with mainly an inch or less falling closer to the city.  The snow was ongoing throughout the day across the southern Poconos, from around 330 a.m. EST to about 9 p.m. EST, with a period of moderate snow between 9 a.m. EST and 3 p.m. EST that contributed to higher accumulations.  Elsewhere, the expanding precipitation shield from the strengthening surface low pressure yielded snow beginning between 8 a.m. EST and 10 a.m. EST across the Lehigh Valley, Berks County, and into southeastern Pennsylvania.  Snow totals were somewhat higher into the Lehigh Valley and Berks County as air temperatures were a little colder through the event, and increased snowfall rates with a period of moderate snow in the early afternoon allowed for higher accumulations.  Meanwhile, closer to the city of Philadelphia, the precipitation began as rain around 830 a.m. EST, with some mixing with sleet and a changeover to snow occurring during the afternoon of the 15th as air temperatures cooled somewhat.  As low pressure quickly advanced east and off the coast by late-day, snow generally ended across much of eastern Pennsylvania between 5 p.m. EST and 7 p.m. EST, with lingering snow in the Poconos until about 9 p.m. EST.
The weight of the snow on roof tops continued to cause concerns. In Lehigh County, in South Whitehall Township the snow damaged a building which housed four tennis courts. In Upper Macungie Township,  an Amazon warehouse was evacuated because of roofing concerns. In Northampton County, in Wilson Borough, a building on Butler Street which housed a laundromat was evacuated because the structure was buckling. The roadway was closed. In Hanover Township, a Wegman's was closed because of concern over the structural integrity of its roof.
