Latest forecast on how much snow North Jersey will get during storm

A mix of snow, sleet and freezing rain is expected to create slippery travel conditions across parts of North Jersey on Dec. 2, prompting the National Weather Service to issue winter weather advisories for Morris and Sussex counties.

Here’s what to expect for the Dec. 2 storm.

How long will the snow last?

The National Weather Service said residents in the Garden State can expect rain, snow, freezing rain and sleet early in the day, becoming all rain after 10 a.m. Precipitation is expected to transition to all rain by late morning, with temperatures reaching around 39 degrees.

NJ declares state of emergency

Gov. Phil Murphy declared a state of emergency for parts of North Jersey. The state of emergency, under Executive Order No. 406, took effect at 5 a.m. for Hunterdon, Morris, Passaic, Sussex and Warren counties due to a “potentially significant winter storm” bringing heavy snow, sleet and freezing rain, the governor’s office said.

“Starting early tomorrow morning, we will experience potentially significant winter weather resulting in hazardous conditions in the northwestern part of our state,” Murphy said in a statement announcing the order. He urged drivers in the affected counties to “exercise caution, remain alert, and follow all safety protocols.”

Winter advisory by the NWS

The advisory for Morris County remains in effect until 1 p.m., with forecasters calling for up to an inch of snow and locally 2 inches at higher elevations, along with a light glaze of ice.

Farther north, Sussex County is under an advisory until 7 p.m., where the storm is expected to linger longer. A light glaze of ice is also possible as a wintry mix persists into the afternoon before changing to rain.

Roads may become slick during the morning commute, the weather service said.

Forecasters said the combination of light snow, sleet and patchy ice could cause hazardous travel, particularly during the morning commute. Drivers are urged to slow down, leave extra space between vehicles and use caution on untreated roads.

Residents can check updated road conditions by calling 511, according to state transportation officials.

Which schools have closed down?

The forecast led to many schools in the region to either close or call a delayed opening. Most of the districts are in Morris or Sussex counties. See the full list here.

Predicted snow inch counts by NJ town

Snow totals around 0.5 inch were expected in towns such as Morristown, Millburn, New Brunswick, Bergenfield, Bloomfield, Caldwell, Clinton, Flemington, Hackensack, Harrison, Lyndhurst, Paramus, Ramsey, Somerville, and Trenton.

Farther north, Sussex County is expected to see the highest totals, with 2 inches in Sussex Borough and Wantage, and around 1 inch in West Milford and Hackettstown, before the precipitation changes to rain later in the afternoon.

In Bergen County, little or no accumulation expected in places like Ridgewood, Rutherford, and Secaucus. Towns farther west and north may still pick up around half an inch, but widespread accumulation is not anticipated. Areas across central and southern New Jersey, including Cherry Hill, Freehold, and Glassboro, are expected to see no accumulating snow.
