N.J. weather update: Up to 6 inches of snow possible this weekend

By Jeff Goldman | NJ Advance Media for NJ.com

A wild swing in the weather is expected over the next few days in New Jersey, with temperatures reaching the 60s Thursday afternoon ahead of a colder weekend with the chance for up to 4 to 6 inches of snow in the state's northern counties Saturday night into Sunday morning.

The quick-moving storm, which could produce some sleet and a mix of snow and rain in warmer parts of the state, is expected to arrive around late Saturday afternoon and end by daybreak Sunday.

This forecast map was updated by the National Weather Service's New York regional office at 3:30 p.m. Thursday. The snowfall projections for Newark and New York City are now slightly lower than they were in the morning, and the projections for the West Milford area are now higher.

The National Weather Service's original forecast called for 3 to 4 inches of snow in northern parts of New Jersey, including areas around Newark, Paramus, West Milford and Morristown. In its updated forecast, issued late Thursday afternoon, the weather service is now predicting 4 to 6 inches of snow in Morris, Sussex, Warren and western Passaic counties, and only 2 to 3 inches in Newark and New York City.

Little, if any, snow is expected along the Jersey Shore and in southern New Jersey, because temperatures will likely be too warm to support snow. Forecasters said rain is more likely in those areas.

The Philadelphia area could get 2 to 3 inches of snow this weekend, but the city's suburbs in western New Jersey are likely to get less than 1 inch of snow, based on the weather service's latest forecast.

Far southern cities like Atlantic City and Cape May are also forecast to get less than 1 inch of snow.

"At this time, we think that areas north of the I-95 corridor should stay all snow and could see anywhere from 3-5 inches of snow," the National Weather Service's regional office in Mount Holly said in its latest forecast discussion.

"Areas along the I-95/I-295 corridor will be the transition zone and see 1-3 inches of snow, with sleet and rain mixing in at times during the evening, before changing back to snow overnight," the weather service said. "The remainder of the area across the coast and southern areas should see less than an inch as they are the likely areas to change over to all rain, or a mix of rain and sleet/snow during the evening hours, before possibly changing back to snow."
