A nor'easter that will move up the Mid-Atlantic coast on Monday night looks like it will spare the Philadelphia region any serious snowfall.
According to the National Weather Service, the current track of the storm will translate to two inches or less of snow in the city, Pennsylvania suburbs and South Jersey. Northern parts of the Jersey Shore could see 3 inches of snow.
Forecasters said there remains uncertainty as to the track of the system. If it moves closer to the coast, more snow would accumulate.
The precipitation, a result of a low pressure system off the Carolina coast that will strengthen as it moves offshore to the northeast, will likely start as rain Monday afternoon south of the city and move north into the city. Meanwhile, temperatures will continue to drop, enabling a changeover to snow. That changeover could happen around 9 p.m. Monday in Philadelphia, and perhaps an hour earlier in the westernmost parts of Chester County.
Winds will remain gusty through Monday and overnight Tuesday for southern and eastern New Jersey, as well as central and southern Delmarva, and will likely begin to gust 20-25 mph by late Monday afternoon.
Gale force wind gusts of 35-40 knots are expected late Monday into Tuesday morning for the Atlantic coastal waters of Delaware and New Jersey, including the lower Delaware Bay. Gale force gusts may linger into Tuesday afternoon. Seas will build to near 10 feet late Monday night.
