STORM DESCRIPTION A coastal low pressure system brought heavy wet snow to most of New Jersey from northern Burlington and Ocean Counties northward.  Synoptic Discussion With cold air over the Northeast, a low pressure system developed along the Gulf Coast on the morning of the 13th.  By the morning of the 14th, it had moved into Alabama and was slowly intensifying.  By daybreak on the 15th the low was located just east of the Delmarva Penninsula.  During the day on the 15th the storm intensified and rapidly moved off-shore, reaching Nova Scotia on the morning of the 16th. Local Discusion This was the heaviest snow to affect so much of the state simultaneously since 1997.  As the low moved towards the Mid-Atlantic states during the day on the 14th, precipitation overspread the area.  Precipitation started as snow in the early afternoon of the 14th in the northwestern part of the state.  Farther south, the low-level air had warmed enough for precipitation to start as rain.  However, as the intensity increased, the precipitation changed to snow in most areas between 2 pm and 4 pm EST.  The wet snow became heavy overnight as the low approached the Mid-Atlantic coast.  The rain/snow line had a difficult time lifting north of the Salem/Cumberland County line, western Atlantic County, southern Burlington County, and eastern Ocean County area.  In Salem County, precipitation changed from snow to rain and back to snow until finally changing to rain for good during the late evening of the 14th.  The snow changed to rain around midnight EST in Mt. Holly and changed to rain around 1 am EST in Trenton.  Precipitation ended as snow in the northwest part of the state.  Accumulations in southwest New Jersey averaged between 2 and 4 inches, while further north 4 to 8 inches was the rule, with isolated higher amounts.
