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. Further to the south, precipitation began as rain and gradually changed over to snow on Monday Night. Snowfall amounts over Eastern Pennsylvania ranged from 3 to 5 inches across the Southern Poconos, 1 to 3 inches over the Lehigh Valley, and generally less than one inch further southeast.
