N.J. weather: Wind chills could hit -15 degrees overnight with up to 50 mph winds in forecast

Dangerously cold wind chills between zero and -15 degrees with gusts up to 50 mph are in the forecast overnight into Sunday morning.

The chances for snow tonight have dropped to just a dusting possible along the southern Jersey Shore as a strong storm passes well off the coast.

“An impactful storm that is bringing significant snow to North Carolina and southern Virginia will just brush our area as it moves out to sea to our south and east,” the National Weather Service said Saturday evening. “The main concerns with the offshore storm for our region are strong winds and coastal flooding.”

The strongest winds will develop after midnight Saturday and continue through early to mid-afternoon Sunday.

A cold weather advisory is in effect for all of New Jersey until 10 a.m. Sunday morning.

The combination of cold temperatures in the low to mid-20s and gusty winds will create wind chills below zero across much of the state.

Wind chills could be as low as 10 to 15 degrees below zero in northwestern counties.

Minor tidal flooding is expected during the Sunday morning high tide cycle from Barnegat Bay to Cape May. A coastal flood advisory is in effect for those counties.

Ice already forming on bays could be pushed onshore during high tides, and flood waters could freeze on roadways, creating hazardous conditions, the weather service said.

Temperatures will remain below freezing through much of next week, with highs only reaching the low to mid-20s on Sunday.

Parts of southern New Jersey may see temperatures rise slightly above freezing on Tuesday and potentially again on Wednesday, though most of the state is forecast to stay below freezing.

This cold snap, which began last weekend, is on track to become one of the top five longest stretches of below-freezing temperatures.

The long-range forecast includes two chances for snow next week.

A weak system may bring light snow to the region on Wednesday, with a 15 to 35% chance of precipitation across areas south of I-78.

An Alberta Clipper system moving through Friday into Friday night could bring a 25 to 40% chance of light snowfall across New Jersey.

Temperatures are expected to remain 10 to 15 degrees below normal through the extended forecast period.
