A cold front moved through the region on December 12th. Behind this front, high pressure settled into northern New England providing colder air into the region. An area of low pressure then developed along the aforementioned front across the Tennessee Valley. This storm then tracked northeastward on December 13th, spreading moisture across the entire region. This storm produced one to as much as 6 inches of snow and sleet across northern New Jersey, however warmer air arrived well above the surface allowing freezing rain to fall for a time in parts of northern New Jersey. Some places picked up one-quarter of an inch of ice with more isolated areas getting as much as one-half inch of ice. The storm then moved out of the area during the first half of the night on the 13th.
The combination of snow, sleet and freezing rain lead to icy conditions across most of northern New Jersey. In Middlesex County, a Woodbridge firefighter was injured after their fire truck slid on the ice and hit two utility poles. Icing in Morris County caused trees to be downed onto train lines near Madison. Across northwestern New Jersey, schools and businesses closed early and that lead to an early start to the evening commute on the 13th. The State Police reported some 300 accidents occurred by late afternoon on the 13th.
Snow and sleet accumulations included 5.5 inches in Wantage (Sussex County); 5.0 inches in Sussex (Sussex County); 3.5 inches in Butler (Morris County), Marcella (Morris County) and Blairstown (Warren County); 3.0 inches in Boonton (Morris County) and Hopatcong (Sussex County); 2.0 inches in Belvidere (Warren County); 1.5 inches in Oakland Mills (Monmouth County); 0.8 of an inch in Edison (Middlesex County), Branchburg Park (Somerset County), Hamilton Square (Mercer County) and Hopewell (Mercer County); 0.6 of an inch in Stewartsville (Warren County); 0.5 of an inch in New Brunswick (Middlesex County), Hillsborough (Somerset County) and Whitehouse (Hunterdon County); 0.4 and inch in Bedminster (Somerset County) and 0.3 of an inch (all sleet) in Ewing (Mercer County).
