New Jersey is staring down its most consequential winter storm of the season, with a sprawling system poised to drop significant snow this weekend. Forecast models agree that a major swath of the state will turn white, but the exact totals hinge on a storm track that is still wobbling. I am looking at a setup where some communities could be measuring snow in shovelfuls while others see a more modest coating, even just a few miles apart.
The core question is not whether it will snow, but how deep the drifts will get from the Shore to the Skylands. With a powerful coastal low tied to Winter Storm Fern feeding on Arctic air, the ingredients are in place for disruptive accumulations, hazardous travel and biting cold. The next 48 hours of data will determine whether this becomes a plow-all-night event or a more manageable winter hit.
Fern’s massive footprint and what it means for New Jersey
The storm threatening New Jersey is part of Winter Storm Fern, a sprawling system already targeting the Deep South and the East Coast with heavy snow, sleet and freezing rain. Meteorologists tracking Fern expect it to unleash up to 20 inches of frozen precipitation in parts of its path, a sign of how much moisture and energy this setup is carrying as it sweeps from the South toward the Mid-Atlantic and New England Winter Storm Fern. That broader context matters for New Jersey, because a storm this strong tends to create a sharp gradient between jackpot snow zones and areas that get grazed.
Farther north, the National Weather Service in New Jersey is already flagging what it calls an increasing potential for an impactful winter storm, with at least a low-end expectation of two or more inches of accumulation across a wide area National Weather Service. That baseline is important: it tells me that even in a more conservative scenario, most of the state will be plowing and salting. In a more aggressive track, those totals could climb quickly, especially where Fern’s moisture overlaps with entrenched Arctic air.
North Jersey: poised for the highest totals
Right now, the strongest signal for deep snow is in North Jersey, where overlapping guidance points to a higher probability of plowable accumulations. A regional map shows a 40 to 50% chance of at least 5 inches of snow for much of the northern tier, including Sussex and northern Passaic counties, which puts those communities squarely in the conversation for the heaviest bands if the coastal low hugs the shore 40 to 50%. Fresh off a weekend with multiple rounds of snowfall, residents there are already dealing with compacted snowpack and narrowed streets, so even a moderate new event will have outsized impacts.
Forecast discussions focused on North Jers emphasize that the region sits close to the axis of coldest air and strongest lift, especially from the New York City area into the higher elevations North Jers. Some of winter’s coldest temperatures thus far are descending on this part of the state, with an Arctic airmass ensuring that whatever falls will stick quickly and stay frozen on untreated surfaces Old Man Winter. With highs in nearby New York City only expected to be in the teens, the air mass feeding into North Jersey will be very dry and very cold, which favors lighter, fluffier snow that can pile up quickly if the moisture firehose points in the right direction Highs.
Central and South Jersey: sharp gradients and coastal wild cards
Farther south, the picture becomes more nuanced, with Central and South Jersey sitting closer to the storm’s coastal low and the Atlantic’s relatively milder influence. Guidance highlighted by Risha Inaganti of the Cherry Hill Courier-Post notes that the winter weather may continue to keep South Jerseyans on edge over the weekend, with accumulating snow likely but totals highly sensitive to the exact track and intensity of the coastal circulation Risha Inaganti. In some scenarios, a slightly offshore track keeps the air column cold enough for several inches of powder from Camden County down through Cape May; in others, a closer pass introduces mixing that trims totals near the immediate coast.
One key metric I am watching is the potential for a sharp north to south snowfall gradient, where communities along the Interstate 195 corridor could see a meaningful difference in depth compared with the Shore or the Delaware River. Reporting that urges South Jerseyans to prepare for a stormy weekend also cites a figure of 54, a reminder that even modest snow combined with strong winds and subfreezing temperatures can create dangerous wind chills and patchy power issues if heavy, wet snow clings to lines and trees 54. An Update describing Old Man Winter with Cold and Snow arriving in South Jersey underscores that an Arctic airmass will be in place before the main storm arrives, so it will be cold enough for snow even in typically marginal coastal zones South Jersey.
Why forecasters are confident about a storm but cautious on totals
Across the Mid-Atlantic, The National Weather Service is stressing that the potential for a substantial winter storm this weekend is high, even as it keeps snowfall ranges broad in its early outlooks The Brief. That cautious tone reflects a familiar winter forecasting challenge: small shifts in the storm’s track or intensity can move the heaviest snow band by tens of miles, dramatically changing who sees 2 inches versus 8 or more. In New Jersey, forecasters are threading the needle between alerting the public to a likely high-impact event and avoiding overconfident maps that will need major revisions.
Coverage focused on N.J. weather notes that the weekend winter storm threat remains high, but snow totals are uncertain, with forecasters watching how the coastal low interacts with a strong high to the north and how quickly the cold air deepens over the state Weekend. I see a similar message in broader national coverage, where Over 30 states are expected to feel the impact of this major winter storm from the South to the East Coast, with heavy snow, blizzard conditions and widespread power outages all on the table in the hardest hit zones Over 30 states. When a system is this large, local details often come into focus only in the final day or two, which is why meteorologists keep urging residents to check updated briefings rather than locking in on a single early model run.
How deep could it get, and how should New Jersey prepare?
So how deep might the snow get in New Jersey by the time the last flakes fall? Based on the current blend of guidance, I see a realistic range where North Jersey has the best shot at 5 inches or more, Central Jersey sits in a middle band of several inches, and South Jersey faces a wider spread that could run from a slushy few inches near the coast to more solid totals inland. A regional outlook framed around another NJ storm notes that the state is Fresh off a weekend with multiple rounds of snowfall, which means even moderate new accumulations will stack on existing ice and snowpack and make travel more treacherous than the raw numbers alone might suggest Fresh. A companion map focused on How much snow are we getting this weekend in North Jersey reinforces that the 40 to 50% probability of at least 5 inches is a key benchmark for planning in the northern counties How much snow.
