The New Year began on a very wet note across New Jersey as a deep southerly flow from the Gulf of Mexico helped drop heavy rain across the state. Rain began falling at or slightly after the New Year began and ended during the early afternoon. The heaviest rain fell in the west central and southwest part of the state. This caused poor drainage flooding, contributed to minor tidal flooding along tidal sections of the Delaware River and some river flooding in Somerset County. Storm totals across the state averaged 1 to 2 inches with the lightest amounts in Warren and Sussex Counties.
The slow moving frontal system that wrung the heavy rain across the region moved from the Tennessee Valley on the morning of December 31st, east to the Ohio Valley and southern Appalachians at 7 p.m. EST on the 31st, to the central Appalachians at 1 a.m. EST on January 1st. As the front started to cross the Pennsylvania, Maryland and West Virginia Appalachians during the morning of January 1st, a low pressure system formed on the triple point of the occluded front in northeastern Virginia around 7 a.m. EST on January 1st. The low pressure system then moved northeast through the Delmarva Peninsula and into New Jersey by the early afternoon of January 1st. At 7 p.m. EST on January 1st, the low pressure system reached western Long Island.
