What happened

The episode as NWS CTP wrote it up.

A fast-moving but intense winter storm moved through the region. This system brought moderate to heavy snow to the southern tier of central Pennsylvania, with accumulations ranging between 6 and 10 inches. The rapid strengthening of the surface low pressure system offshore the Mid-Atlantic coast produced thunder-snow and intense snowfall rates within narrow bands wrapping north-westward from the low center. An initial period of light snow occurred early in the morning, followed by a several hour lull in the precipitation. The bulk of the accumulations occurred between 1600 and 2200 EDT. The snow briefly mixed with sleet and freezing rain during the mid afternoon in the Lower Susquehanna Valley.
