Winter in the Garden State is basically a game of geographical roulette. You’ve probably noticed. One town gets hit with four inches of heavy slush while another, just twenty miles south, is merely dealing with a grey, drizzly mess. Honestly, today, Saturday, January 17, 2026, is the perfect example of that Jersey-style weather chaos.
Right now, New Jersey is sitting under a thick blanket of clouds. It’s 35°F outside, but if you step out to grab the mail, it actually feels like 28°F. That’s thanks to an 8 mph wind coming up from the south. It’s that damp, biting kind of cold that finds the gap in your scarf.

The Saturday Mess: Why North Jersey is Hunker-Down Ready
If you’re up in Sparta or hanging around Morristown, you’re already under a Winter Weather Advisory. The National Weather Service isn't playing around—they’re calling for 2 to 4 inches of snow through 4 PM today. The timing is kinda annoying for anyone with weekend plans. Most of the flakes started falling around 1 AM, and the roads are already getting that treacherous, slippery glaze.
Down in Trenton, things look a bit different. The city has actually triggered a Code Blue Alert. When it gets this cold, the local government opens up warming centers like the Sam Naples Senior Center on Chestnut Ave. It's a serious situation for the vulnerable population. Even though the "official" high for the state is hitting 40°F today, the reality on the ground is much grittier.
We’re looking at a 72% chance of light rain during the day, which usually sounds better than snow, but in Jersey, that just means "black ice recipe."
Breaking Down the Numbers
- Current Temp: 35°F (Cloudy)
- Feels Like: 28°F
- Daytime High: 40°F
- Tonight's Low: 32°F
- Wind: 9 mph from the southwest
- Rain Chance: 72% (Day)
- Snow Chance: 20% (Night)
The Polar Vortex is Back (and it’s Grumpy)
Everyone talks about the "January Thaw," and yeah, we had a bit of a break earlier this month. But that’s over. We are officially entering a polar vortex pattern. Chief Meteorologist Dan Zarrow and other regional experts are pointing toward a series of "lobes" of Arctic air that are basically queueing up to smack the East Coast.
This weekend is just the second wave. The real kicker? That’s coming next week.
Some of the models are hinting at "dangerous cold" by Tuesday. We’re talking morning lows near 10 degrees and wind chills that could drop to zero. It’s the kind of weather where your car takes three tries to start and your nose hairs freeze the second you walk out the door. People often think the shore stays warmer, and while the Atlantic does act as a space heater, the coastal division is still only averaging in the mid-30s this month.
What Most People Miss About the 2026 Forecast
There’s a common misconception that a "mild winter" means no snow. That’s a myth. Even though 2025 was one of the hottest years on record globally, New Jersey’s local December was actually the coldest we’ve seen since 2010. We are currently seeing a weird contradiction: the climate is warming, but the jet stream is getting "wavy," which dumps freezing air on us more violently when it does happen.
The 60-day outlook from sources like the Farmers' Almanac and the National Weather Service suggests we’re in a transition from La Niña to a neutral state. Usually, that means more "wetter" winters. So, instead of one massive blizzard, we’re getting these frequent, annoying 2-inch events. They don't look like much on a weather map, but they cause more car accidents than the big storms because people don't take them seriously.

Survival Steps for the Next 48 Hours
- Check your tire pressure. This sudden drop from the 40s to the 20s will trigger that annoying "low pressure" light on your dashboard.
- Watch the sunset. Tonight, the rain is expected to transition into snow showers as the temp hits that 32°F mark. Anything wet on the road is going to turn into a skating rink.
- Morristown Residents: Use the free garage parking. The town usually opens up the DeHart Street garage during these advisories so people can get their cars off the streets for the plows.
- Pipe Check: If you’re in North Jersey where the lows are dipping further, keep those cabinets under the sink open.
Jersey weather is basically a mood swing you can't escape. Whether you’re dealing with the light rain in the south or the four inches of fresh powder in the north, the "feels like" temp is the only number that actually matters today. Stay warm, keep the salt handy, and maybe just stay off the Parkway if you can help it.
Next Step: Check your local municipal website for "Code Blue" status if you or a neighbor need access to warming centers tonight. If you're driving north of I-80, ensure your ice scraper is actually in the car and not buried in the garage.
