What happened

The episode as NWS PBZ wrote it up.

Cold surface temperatures were already in place across the region at least 24 hours leading up to this event. Surface high pressure allowed high temperatures to only reach near freezing while low temperatures bottomed out in the mid-20s. A closed upper level low formed just north of Texas on November 14th and tracked northeast. An abundant amount of moisture from the Gulf of Mexico traveled with the system into the northeast United States. Freezing rain eventually transitioned to snow when northwest flow began on the backside of the surface low. Four to seven inches of snow was measured north of I-80 and in the higher elevations, meanwhile 1 to 3 inches of snow happened elsewhere.
