If you’ve lived in New Jersey long enough, you know the drill. One day you’re scraping a thick sheet of ice off your windshield in Morristown, and forty-eight hours later, people are joggin' in shorts down by the Asbury Park boardwalk. It’s chaotic. It’s Jersey. But as we stare down the barrel of the 2026 winter season, everyone is asking the same thing: when is the real cold hitting, and are we actually getting a decent snowstorm this year?
The extended forecast New Jersey residents are looking at right now is a bit of a head-scratcher. We are currently navigating a "weak" La Niña phase, which usually sounds like meteorologist-speak for "we aren't totally sure." Honestly, though, the data coming out of the Climate Prediction Center (CPC) suggests we’re in for a winter of two halves. If you were hoping for a quiet, easy commute through February, you might want to keep that shovel near the front door.
The La Niña Factor: Why It’s Getting Weird
Most people think La Niña means a guaranteed "Polar Vortex" every other week. Not quite. This year, the cooling of the equatorial Pacific—that’s the La Niña—is behaving a bit stubbornly. It’s weak, but it’s there, and it's expected to linger through at least March.
What does that mean for the Garden State?
Typically, this setup shoves the jet stream north. You get a lot of "clash" weather. Cold air tries to dive down from Canada, but warm, moist air from the Gulf and the Atlantic is constantly pushing back. That’s why your weather app probably looks like a roller coaster right now. One week we’re looking at highs in the 40s, and the next, a "clipper" system threatens to dump three inches of slush on the I-95 corridor.
What to Expect Through February 2026
If you’re planning a trip to the Poconos or just trying to figure out when to salt the driveway, here is the breakdown of the extended forecast New Jersey is facing for the rest of the season.

January: The Arctic Tease
We’ve already seen a few bitter snaps this month. The final week of January looks particularly temperamental. Forecasters at the National Weather Service are watching a negative phase of the Arctic Oscillation.
Basically? The "fence" that keeps the coldest air trapped at the North Pole is breaking down.
When that happens, the cold spills south. Between January 25 and January 31, we’re looking at daytime highs that might struggle to break 30°F in North Jersey, while Cape May might see some messy, rainy mix. It’s that classic Jersey split. The "snow line" is going to be the main character in every local news broadcast for the next ten days.
February: The Potential for "Big Snow"
Historically, February is our snowiest month. The 2026 outlook suggests that as we transition toward "ENSO-neutral" conditions (the middle ground between El Niño and La Niña), the storm tracks might shift.
Instead of those annoying rain-snow mixes that just turn into ice overnight, we have a higher probability of a legitimate Nor'easter. The Old Farmer’s Almanac and several long-range models are pointing toward the second and fourth weeks of February as the high-risk zones.
- Early Feb: We’re looking at a potential warm-up. Don't let it fool you. It’ll likely be rainy and "mucky."
- Late Feb: This is the window to watch. If a coastal low-pressure system develops while that Canadian air is hanging around, we could see the first 6-inch-plus accumulation of the season for Central and North Jersey.
Comparing the Regions: It’s Not One State
You can’t talk about a New Jersey forecast without acknowledging the divide. The "North-South" debate isn't just about Pork Roll vs. Taylor Ham; it’s about the thermometer.
In Sussex and Passaic counties, the ground is likely to stay frozen for most of February. Highs will hover around 35°F. Down in Atlantic and Ocean counties, the Atlantic Ocean acts like a giant heater. It’s much harder to get snow to stick when the water is still relatively mild. If you’re at the Shore, expect more "slop" than "snow." Honestly, it’s the worst of both worlds—cold enough to be miserable, but too warm for the pretty white flakes.

Is This "Normal" Weather?
Not really, but "normal" is a moving target these days. Since about 2010, Jersey winters have trended wetter and warmer on average. This year is fitting that pattern. Even with the cold snaps, the overall seasonal temperature is projected to be about 2 to 3 degrees above the 30-year average.
We’re seeing fewer "consistently cold" winters and more "extreme swing" winters. You get two weeks of spring-like weather in February that makes the tulips start thinking about popping up, followed by a localized blizzard that shuts down the Parkway.
Actionable Tips for Surviving the Rest of the Season
Since the extended forecast New Jersey is looking so volatile, being "sorta prepared" isn't enough.
- Check Your Sump Pump: With the projected "wetter than normal" February and the frequent freeze-thaw cycles, basement flooding is a real risk. Make sure that pump is actually clicking on.
- Ice Melt Strategy: Don't wait until the 10 p.m. news confirms a storm. Grab a bag of calcium chloride now. It works better in lower temperatures than standard rock salt and is slightly less brutal on your dog's paws.
- The "Half-Tank" Rule: In a state known for traffic jams (looking at you, Route 17 and I-80), never let your gas tank or EV charge drop below half during a storm threat. If you get stuck behind a jackknifed rig in a snow squall, you’ll want that heater running.
- Prune the Overhangs: We’ve had a lot of heavy, wet snow in recent years. If you have branches hanging over your roof or power lines, take care of them before the February ice storms hit.
The most important thing to remember? Don't trust a 10-day forecast in New Jersey until it's actually day three. The atmosphere over the Mid-Atlantic is just too chaotic for 100% accuracy that far out. Keep an eye on the "indices"—the Arctic Oscillation and the North Atlantic Oscillation—because those are the real drivers of whether you’ll be wearing a parka or a windbreaker next Tuesday.
Stay warm, keep the windshield fluid topped off, and maybe keep a bag of salt in the trunk. It’s going to be a bumpy ride into March.
Next Steps for New Jersey Residents:
Check the local National Weather Service office in Mount Holly or Upton for "short-term" updates, as these long-range models shift significantly every 48 hours. If you're in a flood-prone area like Manville or Pompton Lakes, monitor the river gauges closely during the rainy warm-ups predicted for early February.
