What happened

The episode as NWS PHI wrote it up.

A late winter storm brought heavy snow to the higher terrain of Monroe County. Accumulations were lighter elsewhere across the Poconos and little if any snow accumulated in the valleys. Precipitation started as snow and sleet over the higher terrain of the Poconos during the late afternoon of the 21st. Accumulations were an inch or less before the precipitation changed to rain. As the low pressure system moved east of the region, it pulled down colder air and the rain changed back to snow around midnight over the higher terrain of Monroe County and fell heavy at times the rest of the overnight into the morning of the 22nd. Enough warm air remained in the valleys for the precipitation to fall mainly as rain until near the end. Accumulations included 7 inches in Tobyhanna and Pocono Summit, 6 inches in Long Pond and 5 inches in White Haven (Luzerne County). There were no accumulations reported in either Lehighton or East Stroudsburg. Since the heavy snow fell late on a Sunday night/Monday morning, few serious accidents were reported. The low pressure system moved northeast from Atlanta, Georgia the morning of the 21st to Albany, New York the morning of the 22nd.
