A winter storm that featured a potpourri of precipitation types affected New Jersey from the afternoon of the 25th into the early morning of the 26th. Snowfall accumulations averaged 1 to 4 inches with the highest amounts in Sussex County. Ice accretions occurred from the Raritan Basin southward and averaged one-tenth to one-quarter of an inch with the highest accretions in the Raritan Basin. Precipitation started as snow (some sleet and rain mixed in at the start well south) during the afternoon of the 25th. In the southeast part of the state, the snow changed to sleet and freezing rain during the late afternoon and then to plain rain by the middle of the evening. Ice accretions were less than one-tenth of an inch. In the southwest part of the state, precipitation changed to sleet and freezing rain during the early evening and to plain rain during the late evening. Ice accretions were around one-tenth of an inch. Across the Raritan Basin as well as Mercer and Monmouth Counties, precipitation changed to sleet and freezing rain during the late evening and continued to fall as freezing rain in the Raritan Basin until it ended around 4 a.m. EST on the 26th. In Mercer and Monmouth Counties, precipitation changed to rain before it ended. In northwest New Jersey, precipitation fell mainly as snow, but mixed with sleet at times before it ended by 6 a.m. EST on the 26th.
Untreated roads and walkways were hazardous. The snow did accumulate on road surfaces as the weather had remained unseasonably cold. New Jersey State Police responded to about 400 accidents.
Snowfall accumulations included 4.0 inches in Wantage (Sussex County), 3.0 inches in Newton (Sussex County) and Butler (Morris County, 2.6 inches in Blairstown (Warren County), 2.3 inches in Edison (Middlesex County), 2.0 inches in Flemington (Hunterdon County), 1.9 inches in Somerdale (Camden County), 1.8 inches in Hillsborough (Somerset County), 1.7 inches in Maple Shade (Burlington County), 1.6 inches in Midwood (Ocean County), 1.5 inches in National Park (Gloucester County), 1.2 inches in Pittsgrove (Salem County), 1.1 inches in Hammonton (Atlantic County), 1.0 inch in Ewing (Mercer County) and 0.9 inches in Cape May (Cape May County).
The low pressure system that caused the winter storm moved northeast from the foothills of the central Rockies on the morning of the 24th. At 7 p.m. EST on the 24th it reached Kansas City, Kansas City and then northeastern Iowa at 7 a.m. EST on the 25th. A secondary low pressure system started forming on the primary low's warm front in South Carolina during the early afternoon of the 25th. At 7 p.m. EST the secondary low was near Raleigh, North Carolina, while the primary low pressure system was weakening near Chicago, Illinois. At 1 a.m. EST on the 26th, the secondary low pressure system was just east of the Delaware coast and at 7 a.m. EST that morning was already well southeast of Cape Cod, Massachusetts. While warm air continued to move in aloft because of the circulation associated with the primary low pressure system, the formation and deepening of the secondary low pressure system slowed the advancement of warmer air near the surface and prolonged the duration of sleet and freezing rain inland, especially in the Raritan Basin. The secondary low pressure system moved offshore too quickly to bring heavy snow into northwest New Jersey.
