Honestly, if you’ve lived in Union County for more than a week, you know the drill. You check the app, it says "flurries," and suddenly you’re digging your SUV out of a drift on Westfield Ave. This Sunday, January 18, 2026, is proving to be one of those days where the weather forecast Clark NJ isn't just a suggestion—it’s a full-blown event.
Right now, as the sun sets, we’re sitting at a crisp 32°F. It feels more like 27°F though, thanks to a 6 mph wind coming out of the north. If you’re looking out the window, you’ve probably noticed that "winter wonderland" vibe has turned into a messy "rain and snow" mix. It’s heavy, it’s wet, and with 90% humidity, it’s the kind of cold that sinks right into your bones.
The Reality of This Snow Storm
Most people see "snow" and think of a few pretty flakes. Not today. We are currently under a Winter Weather Advisory that stays active until midnight. The weather forecast Clark NJ is calling for a heavy snow storm during the day with a 100% chance of precipitation.

Basically, it’s a total washout—or "white-out," technically. We are looking at a high of 33°F and a low of 24°F. While the accumulation isn't record-breaking—most local gauges are seeing about 1 to 3 inches—the timing is the real kicker. It started as freezing fog this morning and has transitioned into this heavy, slushy mess that makes the Garden State Parkway feel like an ice rink.
What the Numbers Actually Mean
- Current Temp: 32°F (Feels like 27°F)
- Wind: 6 mph from the North
- Precipitation: 94% chance of snow right now
- Tonight’s Low: 24°F
If you’re planning to head out to the Rahway Soup Stroll or thinking about driving over to Westfield for that guitar duo performance, you might want to rethink the footwear. The untreated surfaces are incredibly slippery. I’ve seen enough people sliding around the ShopRite parking lot today to know that "caution" is the word of the hour.
Why Clark Weather is So Unpredictable
People always ask why the weather forecast Clark NJ seems to change every twenty minutes. It’s the "Jersey Gap" effect. We’re tucked right between the influence of the Atlantic and the colder air moving down from the Kittatinny Mountains.
Historically, January is our coldest month. We usually see an average high of 37°F, but today we’re struggling to even hit that. According to the Rutgers Climate Lab, we’ve been trending a bit drier lately, but this specific storm is a reminder that the "January Thaw" we had earlier this month was just a tease.
Looking Ahead to MLK Day
If you’re off for Martin Luther King Jr. Day tomorrow, there's a light at the end of the tunnel. The snow should taper off by midnight, leaving us with a mostly sunny Monday. But don't let the sun fool you. The high will stay around 33°F, and the wind is going to kick up to about 10–20 mph.
With a low of 16°F tomorrow night, anything that melted today is going to turn into solid black ice. If you have to commute on Tuesday, give yourself an extra fifteen minutes. It’s going to be a "frozen tundra" situation with a high of only 24°F.
Actionable Steps for Clark Residents
Since this snow is the heavy, wet kind, it’s not the light stuff you can just leaf-blow off your porch.
- Clear the slush now: Before the temperature drops to 24°F tonight, get that slush off your driveway. If you leave it, it will be a sheet of ice by 6:00 AM.
- Check your tires: With the wind shifting to the northwest at 5–10 mph tonight, drifting might be minimal, but traction is the real issue.
- Watch the "Feels Like": Even if the thermometer says 33°F, that wind chill is going to be in the teens by tomorrow morning. Layers aren't optional.
The weather forecast Clark NJ is finally giving us a real winter experience after a weirdly mild start to 2026. Stay warm, stay off the roads if you can, and maybe finally finish that book you started on New Year's Day.
