A winter storm dropped heavy snow and sleet as well as some freezing rain across most of New Jersey, except for the immediate coast. Snowfall and sleet totals average 10 to 20 inches from around the Interstate 95 corridor northwestward with the highest amounts in Warren and Sussex Counties. Elsewhere, snowfall and sleet amounts dropped considerably the closer to the coast municipalities were located. Ice accumulations were generally less than one tenth of an inch. Little if any snow or sleet accumulations occurred along the coastal strips of Cape May and Atlantic Counties.
Snow overspread New Jersey from south to north between 9 p.m. EST and Midnight EST on the 12th. Three bands of heavy snow, in which snowfall rates averaged two to three inches per hour, moved through the state. The first one mainly affected the southern third of the state around 3 a.m. EST on the 13th. The second one moved through the entire southern half of the state (away from the coast where it was rain by then) between 4 a.m. EST and 7 a.m. EST on the 13th. The last one formed in the southern half of the state around 6 a.m. EST on the 13th and proceeded to move north through the entire state by 2 p.m. EST on the 13th. After the snow bands moved through, precipitation changed to rain in the southeast part of the state during the morning of the 13th, the southwest and central part of the state during the second half of the morning and around midday on the 13th and during the afternoon of the 13th in the northwest part of the state. Some pockets of freezing persisted. Thunderstorms moved through the state during the late afternoon and early evening on the 13th, some with small hail. Then as the low pressure system pulled offshore, precipitation changed back to snow during the second half of the evening on the 13th and ended after Midnight EST on the 14th. The last snow band exited New Jersey between 2 a.m. EST and 5 a.m. EST on the 14th.
Governor Chris Christie declared a state of emergency and New Jersey State Offices were closed and non-essential personnel did not have to report to work. Many schools, malls, businesses, other government and  local offices as well as municipal courts never opened on the 13th. Many schools in the northern part of the state were also closed on the 14th. New Jersey State offices opened late on the 14th. There were speed restrictions on the New Jersey Turnpike and the Delaware River crossings.  The early start to the heavy snow cut down on the number of accidents. The New Jersey State Police responded to 334 motor vehicle accidents and 632 calls for assistance. Many of the flights into and out of the Atlantic City International Airport were cancelled. The snow did not cling to tree limbs as well and there were only about 400 homes and businesses that lost power in Public Service Electric and Gas's service area.  One of the hardest hit businesses were florists as the heavy snow wreaked havoc (tens of thousands delayed) on the flower deliveries for Valentine's Day.  The latest event strained municipal budgets further and increased the shortage of salt supplies in the region.  The weight of the snow started to cause structural damage. In Raritan (Somerset County), strip mall roofing collapsed on U.S. Route 202. No injuries occurred.
Representative snowfall included 22.8 inches in Montague Township (Sussex County), 19.2 inches in Highland Lakes (Sussex County), 19.1 inches in Blairstown (Warren County), 17.3 inches in Rockaway Township (Morris County), 17.2 inches in Wantage (Sussex County), 16.0 inches in Butler (Morris County), 15.4 inches in Stewartsville (Warren County), 15.3 inches in Boonton (Morris County), 15.2 inches in Bridgewater (Somerset County), 14.5 inches in Marcella (Morris County), 14.4 inches in Greenwich Township (Warren County), 14.0 inches in Kingwood Township (Hunterdon County), 13.8 inches in Bound Brook (Somerset County), 13.1 inches in Metuchen (Middlesex County), 12.7 inches in Florence (Burlington County), 12.2 inches in Westampton Township (Burlington County), 11.6 inches in Washington Township (Gloucester County) and Readington Township (Hunterdon County), 11.5 inches in Clinton Township (Hunterdon County), 11.2 inches in South Plainfield (Middlesex County), 10.6 inches in Burlington Township (Burlington County), 10.5 inches in Flemington (Hunterdon County), 10.0 inches in Moorestown (Burlington County) and Ewing (Mercer County), 9.4 inches in Lindenwold (Camden County), 8.9 inches in Jackson Township (Ocean County), 8.6 inches in Woodstown (Salem County), 8.5 inches in Pitman (Gloucester County),  8.3 inches in Tabernacle (Burlington County), 7.6 inches in Egg Harbor City (Atlantic County), 7.5 inches in Estell Manor (Atlantic County), 4.0 inches in Woodbine (Cape May County), 3.3 inches in Berkeley Township (Ocean County), 3.0 inches at the Atlantic City International Airport and 2.2 inches in Lavallette (Ocean County).

The winter storm was caused by a low pressure system that formed in the western Gulf of Mexico on the 11th and moved east on the 12th. This was preceded by an arctic high pressure system that passed over the Middle Atlantic States that same day and left plenty of initial cold, dry air in place. A new low pressure system formed east of Florida on the 12th and would become the primary low pressure system for the event. It moved northeast and was near Wilmington, North Carolina at 7 p.m. EST on the 12th. From there, it continued northnortheast and passed near Elizabeth City, North Carolina at 7 a.m. EST on the 13th. Once it reached the Atlantic again, it started to intensify rapidly and reached the Delmarva coastal waters early in the afternoon on the 13th. At 7 p.m. EST on the 13th, the low pressure system was off the New Jersey coast and deepened to 986 millibars (11 millibar drop in 12 hours). From there the low pressure system moved northeast and intensified even more rapidly as it passed just east of Long Island, New York and passed near Boston, Massachusetts as a 976 millibar low pressure system at 4 a.m. EST on the 14th. This low pressure system deepened to 968 millibars at 10 a.m. EST on the 14th while over Maine before finally leveling off. The close pass to the New Jersey coast permitted this low pressure system to bring in above freezing (milder) air into the state, if not at the surface, at least aloft and caused a period of non-snow to occur before ending as snow again as it departed.
