What happened
The episode as NWS PHI wrote it up.
A clipper low pressure system dropped on average 1 to 2 inches of snow across northwest New Jersey during the evening of the 29th into the morning of the 30th. While snow fell into the morning of the 30th, the heaviest snow fell overnight on the 29th preceding the clipper's warm front. Untreated and less traveled roadways were slippery as many morning low temperatures on the 29th were in the single numbers and afternoon high temperatures were below freezing.
Representative snowfall included 2.3 inches in Wantage and Hardyston (Sussex County), 2.1 inches in Jefferson Township (Morris County), 2.0 inches in Highland Lakes (Sussex County), 1.5 inches in Marcella (Morris County) and Vernon (Sussex County), 1.2 inches in Rockaway (Morris County) and Bethlehem (Hunterdon County), 1.1 inches in Blairstown (Warren County) and 1.0 inch in Metuchen (Middlesex County), Boonton (Morris County) and Hackettstown (Warren County). While snow from the clipper also fell farther south in New Jersey, snowfall was an inch or less.
The Alberta Clipper low pressure system moved quickly from the Northern Plains on the morning of the 28th to near Chicago on the morning of 29th, crossed Lake Ontario into Canada during the early evening of the 29th and then northeast through the Saint Lawrence River Valley. The snow associated with the system preceded and accompanied its warm and cold fronts.
