The combination of a weak high pressure system over the region and low level moisture left in place by a departing low pressure system to the east caused dense fog to form across central and southern New Jersey after midnight EST on the 19th. Air temperatures were at or below freezing in the area and this permitted black ice to form on area roadways and walkways. Untreated roadways and walkways were slippery. A multi-vehicular pile-up on the Garden State Parkway in Bass River Township (Burlington County) resulted in the death of a 40-year-old woman. Another Garden State Parkway accident in Old Bridge Township (Middlesex County) resulted in the death of a 62-year-old woman.  In Atlantic County, on the Great Egg Bridge in Somers Point, five separate accidents involved twenty-two cars occurred. Lesser black ice and fog related accidents occurred along New Jersey State Route 38 in Mount Laurel (Burlington County) Township and Cherry Hill (Camden County) Township. Air temperatures rose above freezing throughout most of central and southern New Jersey by 10 a.m. EST and ended the black ice problems. The fog dissipated about an hour later.
