We won't see much accumulation Sunday night into Monday. However, the second half of the storm is when the real damage will be done as the storm could intensify enough to bring 18 inches of snow or more to parts of the region.
A fast-moving Alberta clipper moved in between late Sunday and will last into the Monday morning commute - dropping 1 to 3 inches of snow during the day Monday. The second part of the storm will bring major accumulations.
As the storm moves off shore Monday afternoon, it's expected to develop and rapidly intensify into a nor'easter that will then strike the area again around 7 p.m. Monday.
While models differ over the severity of the storm, the latest models from the National Weather Service forecast nearly 20 inches of snow for parts of the area by Tuesday. The nor'easter will bring heavy, blowing snow to the region, hitting Central New Jersey and areas along the Jersey Shore the hardest.
As a result, the Weather Service issued a winter storm warning from noon Monday to 6 p.m. Tuesday for Sussex, Warren, Morris, Hunterdon, Somerset, Mercer, Salem, Gloucester, Camden, Burlington, Delaware, Philadelphia, Montgomery and Upper Bucks counties.
A winter storm watch is also in effect for New Castle, Cecil, Carbon, Monroe, Berks, Lehigh, Northampton and Chester Counties from Monday afternoon through Tuesday morning.
