The episode as NWS PHI wrote it up.
A cold front moved through northern New Jersey on the 15th and stalled over the southern Middle Atlantic States. High pressure brought in some colder and drier air near the surface the night of the 15th and the morning of the 16th. A weak low pressure system developed on the front during the morning of the 16th over the Tennessee Valley. While it was warm enough aloft for precipitation to fall as rain, air temperatures remained below freezing over some of the higher terrain locations in Sussex County, particularly in the northwest part of the county. The low pressure system was too weak to bring in warmer air from the nearby Atlantic Ocean. Freezing rain and rain fell across Sussex County during the day and evening of the 16th. Ice accretions reached around one-quarter of an inch in some of the higher terrain locations in the county. Untreated roadways were treacherous.
