Winter Weather in Pennsylvania, January 16 to 17, 2012
The southwest return flow around a high pressure system coupled with an approaching warm front produced an intermittent, light wintry mix of precipitation across the Philadelphia northwest suburbs, Berks County, the Lehigh Valley and the Poconos. Snowfall accumulations (mainly in the Poconos) were less than half an inch and ice accretions were less than one tenth of an inch, traces in many areas.

What happened
The episode as NWS PHI wrote it up.
The southwest return flow around a high pressure system coupled with an approaching warm front produced an intermittent, light wintry mix of precipitation across the Philadelphia northwest suburbs, Berks County, the Lehigh Valley and the Poconos. Snowfall accumulations (mainly in the Poconos) were less than half an inch and ice accretions were less than one tenth of an inch, traces in many areas. Untreated surfaces were hazardous to drive or walk on. Precipitation overspread the region during the early to middle of the evening and fell as mainly sleet and freezing rain, but started briefly as snow in the Poconos. As warmer air moved in aloft and a bit at the surface, the intermittent precipitation changed to plain rain in Berks County and the Philadelphia northwest suburbs and fell as either sleet or freezing rain in the Lehigh Valley and Poconos. Temperatures either rose above freezing or precipitation ended by 7 a.m. EST on the morning of the 17th in these latter locations.
