What happened

The episode as NWS PHI wrote it up.

A low pressure system developed in the western Gulf of Mexico during the day on the 28th. It slowly moved eastnortheast and by Sunday morning the 30th was located near Apalachicola Florida, not too far from the location of the January 25th storm. Unlike the previous storm, this one tracked farther to the west and moved northeast along the Atlantic Seaboard. By the morning of the 31st, it was located near Boston, Massachusetts. There was less cold air present at the start of the storm, especially along the coastal plain. Most of it was in the lowest layers of the atmosphere. This led to the more typical potpourri of weather across New Jersey with primarily rain in the southeast part of the state and heavy snow in the northwest part of the state.Precipitation started during the afternoon as snow throughout most of the state. Along the coast and in the southeast part of the state enough warm air was already present for precipitation to just briefly start as either sleet or rain before changing to rain. By early evening precipitation had changed to sleet and freezing rain across the southwest part of the state, but still falling as snow in the west central and northwest part of the state. By 9 p.m. EST enough warm air had moved into the southwest part of the state to change the precipitation to plain rain. Meanwhile at that time a transition to sleet and freezing rain was occurring in the west central and northwest part of the state. The cold air was deep enough in Sussex County for precipitation to continue to fall as mainly snow. By 10 p.m. EST sleet had made it as far north as Warren County. Precipitation ended from south to north from midnight through 3 a.m. EST on the 31st. Temperatures never made it above freezing in the northwest part of the state. Accumulations were highest in the northwest part of the state where precipitation fell as snow the longest. The greatest accretion of ice, around one-quarter of an inch, occurred in townships along the Delaware River from Salem County to Mercer County. The ice brought down a couple of power lines and caused isolated outages. Untreated roadways were very treacherous and high traffic volume due to Super Bowl Sunday exacerbated the problems. Snowfall accumulations of an inch or more included: in Sussex County 8.5 inches in Stillwater, 7.5 inches in High Point, 7 inches in Highland Lakes, 6.5 inches in Wantage and 6 inches in Sparta; in Warren County 8 inches in Belvidere and 7 inches in Blairstown; in Morris County 5.5 inches in Marcella, 5 inches in Long Valley and 4.5 inches in Morristown; in Hunterdon County 6 inches in Reigelsville, 5 inches in Bloomsbury and 4 inches in White House Station; in Somerset County 2 inches in Somerville, in Middlesex County, 1.8 inches in New Brunswick and in Mercer County 1.5 inches in Hamilton Square.
