A double shot of wintry precipitation affected New Jersey mainly during the evening of the 15th and again during the daytime hours of the 16th. Total snowfall from both events averaged one to three inches, except it ranged from three to seven inches in Sussex and Morris Counties. The first shot of precipitation started as snow in the evening of the 15th. Precipitation fell mainly as rain in southeast New Jersey.  The snow changed over to freezing rain in southwest New Jersey just before it ended. The heaviest snowfall with the first band affected the Raritan Basin. Precipitation ended during the early morning of the 16th except in parts of Morris County where lighter snow persisted. Snow overspread the entire state again during the morning of the 16th and ended late that afternoon. The second shot of snow lasted for about six hours. Untreated roadways were slippery, especially during the first precipitation shot as it fell at night and also in northwest New Jersey because of the heavier snowfall.
Snowfall included 6.5 inches in Vernon Valley (Sussex County), 5.0 inches in Butler (Morris County), 4.5 inches in Marcella (Morris County), 4.0 inches in Wantage (Sussex County), 3.5 inches in Lafayette (Sussex County), 3.2 inches in Ewing (Mercer County), 2.5 inches in New Brunswick (Middlesex County), 2.3 inches in Branchburg (Somerset County), 2.0 inches in Malaga (Gloucester County) and Tewksbury (Hunterdon County), 1.5 inches in Mount Holly (Burlington County), 1.4 inches in Hammonton (Atlantic County) and Cream Ridge (Monmouth County), 1.2 inches in Beachwood (Ocean County) and 1.0 inch in Vineland (Cumberland County) and Philipsburg (Warren County).
The double shot of wintry precipitation was caused by a low pressure system and its upper level support. The low pressure system moved from the Ohio Valley on the morning of the 15th northeast into western Pennsylvania during the early evening of the 15th. A new low pressure system formed on the triple point of its occluded, warm and cold fronts in Virginia early that evening. This low pressure system moved northeast and was off the New Jersey coast shortly after Midnight EST on the 16th ending the first shot of precipitation for most. The second shot of precipitation occurred as an upper level low moved across the southern part of the state during the daytime hours on the 16th.
