What happened

The episode as NWS PHI wrote it up.

Low pressure along an occluded front in the Tennessee Valley redeveloped off the North Carolina Coast on Monday Night March 12th and underwent rapid deepening as it moved northeast toward to the 40 North/70 West benchmark coordinates on the Tuesday Morning March 13th. This strong low and a weaker area of low pressure in the Great Lakes lead to the development of precipitation across the region on the afternoon of the 12th, which persisted into the morning of the 13th. The precipitation was mainly snow to the north of The Pennsylvania Turnpike and Interstate 195 corridors. Further to the south, precipitation began as rain and gradually changed over to snow on Monday Night. Across New Jersey, 3 to 6 inches of snow fell to the north of the I-80 corridor and across portions of Monmouth County, with locally higher amounts. Elsewhere, 1 to 3 inches of snow was the rule, except south of the Atlantic City Expressway, where amounts tapered off to a Trace.
