The episode as NWS PBZ wrote it up.
Rain showers changed to snow on the evening of November 1st, behind a cold front that brought an early shot of cold air to western Pennsylvania. Northwest flow, which helped to provide enhancement to the snow from Lake Erie, kept snow showers going through most of the following night, with some accumulations reported. An enhanced band that extended into Mercer County was responsible for the event's highest snow totals.
