A clipper low pressure system dropped 1 to 3 inches of snow across the southern half and less than an inch across the northern half of New Jersey during the afternoon and evening on the 21st. The snow helped cause slippery traveling conditions and accidents. There were about three dozen accidents or incidents on major roadways in the southern half of the state. In Burlington County, an accident with injuries occurred on southbound U.S. Route 206 in Mansfield Township. In Ocean County, in Toms River, a 17-year-old driver was injured after the SUV flipped over and skidded off the roadway. Speed reductions were in effect in the southern half of the state on the New Jersey Turnpike and Garden State Parkway.  PATCO Rail Commuter High Speed Lines had 15 minute delays during the evening commute.
The snow spread from south to north and began falling between 2 p.m. EST and 4 p.m. EST on the 21st. The snow fell moderately at times in southeast New Jersey during the late afternoon. The snow ended between 6 p.m. EST and 10 p.m. EST on the 21st. Representative snowfall included 3.1 inches in Newport (Cumberland County), 3.0 inches in Seaville (Cape May County), 2.9 inches in Estell Manor (Atlantic County) and Lacey Township (Ocean County), 2.5 inches in Margate (Atlantic County) and Sea Isle City (Cape May County), 2.0 inches at the Atlantic City International Airport and Harvey Cedars (Ocean County), 1.8 inches in North Cape May (Cape May County), 1.6 inches in Seabrook (Cumberland County), 1.3 inches in Tabernacle (Burlington County) and Pitman (Gloucester County), 1.2 inches in Pennsville (Salem County), 1.0 inch in Berlin (Camden County) and Toms River (Ocean County), 0.8 inches in Somerdale (Camden County) and 0.7 inches in Delran Township (Burlington County).
