An area of high pressure moved across the region during the 6th. This allowed colder and much drier air to settle southward into the Middle Atlantic region. Meanwhile, an area of low pressure organized across the Tennessee Valley during the morning of the 6th and tracked northward to the northern Ohio Valley during the evening of the 6th. An abundance of moisture surged well ahead of this storm. Some areas experienced some sleet and snow to start as the precipitation intensity was rather light. As the precipitation intensified and increased in areal coverage, freezing rain, sleet, rain and even some snow occurred. However, freezing rain and rain were the dominant precipitation type. Significant icing occurred across northwestern New Jersey, with a coating of ice all the way down to portions of west-central and southwestern New Jersey. The main low pressure system then tracked to the north on the 7th, as a secondary low pressure center formed just south of Long Island. The two systems produced plenty of rain across the area, although freezing rain held on across a portion of northwestern New Jersey for nearly the entire duration. An associated cold front finally moved through the region during the evening of the 7th, which brought drier air into the area.
The most significant icing occurred across Warren, Hunterdon, Morris and especially Sussex counties. Icy conditions in Warren County contributed to an accident on Interstate 80 at Mile Marker 2. The accident, which occurred on a section of the ���S��� turns, slowed traffic for more than an hour during the morning of the 7th.
About 400 customers scattered throughout Morris County lost power by about 12:00 PM EST on the 7th, primarily due to ice-laden tree branches that fell onto electrical lines. In Randolph, the westbound lanes of Route 10 were closed at Dover-Chester Road in the morning of the 7th because a tree fell across the highway, which blocked all three westbound lanes. In Morris Township, Sussex Avenue was closed from Sudberry Drive to Bradwahl Drive because a tree fell due to the accumulated ice and brought down utility wires around 2:20 PM EST on the 7th. In Mount Olive, 10 weather-related vehicle accidents were reported between 5:00 PM EST on the 7th and 7:00 AM EST on the 8th. No serious injuries were reported. School districts throughout Morris County had delayed openings while a few closed on the 7th. In Washington Township, a few back roads were closed during the early morning hours of the 8th due to icy conditions. In Jefferson, weather accounted for a rollover accident on Ridge Road during the afternoon on the 8th but resulted in no injuries. There were also six traffic accidents and a downed wire on Berkshire Valley Road. In Sussex County, about 600 customers were without power on the 7th. In the High Point and Wantage areas, ice accumulations were up to one half of an inch and coated all surfaces. This resulted in very slippery conditions and it was reported that the air temperature never got above freezing.
Some specific ice accumulation reports included; 0.50 inches in Wantage (Sussex County), 0.40 inches in Alalmuchy and Blairstown (Warren County), 0.30 inches in Butler (Morris County) and Whitehouse (Hunterdon County), 0.25 inches in Newton (Sussex County), Rockaway and Lake Hopatcong (Morris County), 0.15 inches in Oak Ridge (Morris County), 0.10 inches in Mount Holly and Edgewater Park (Burlington County).
