Honestly, if you've lived in Montclair for more than a week, you know the drill. You wake up thinking it’s a light sweater kind of morning, and by noon you’re digging through the hall closet for that heavy parka you swore you wouldn't need until February.
Checking the 10 day weather forecast montclair nj isn't just a casual habit; it’s a survival tactic. Right now, as we sit in the middle of January 2026, the atmosphere is basically throwing a tantrum. We’re currently hovering at a chilly 31°F, but with the humidity at 55% and a slight south wind at 4 mph, it feels more like 27°F. It’s that damp, New Jersey cold that gets right into your bones.
The Immediate Outlook: Snow is Actually Happening
Forget the "maybe" or the "slight chance." Today, Saturday, January 17, is a snow day. We’re looking at a high of 37°F with a 75% chance of snow during the day, transitioning into light snow tonight as it drops to 31°F. It’s not a blizzard, but it’s enough to make the commute on Bloomfield Avenue a total mess.
Tomorrow doesn't offer much of a break. Sunday brings snow showers with a high of 36°F. The real kicker is Sunday night. The temperature is going to tank down to 23°F. If you haven't dripped your faucets yet, tonight might be the night to start thinking about it.
The Brutal Mid-Week Shift
Monday, January 19, looks deceivingly nice. It’ll be sunny with a high of 34°F. Don’t let that sun fool you. A 14 mph southwest wind is going to make that 34°F feel significantly more aggressive.
Then comes Tuesday.
Tuesday, January 20, is when the polar vortex decides to remind us who’s boss. We are looking at a high of only 22°F and a low of 13°F. That is "stay inside and order Tierney’s" weather. It’s clear and sunny, but at 13°F, the air is basically made of ice needles.
Looking Further Out: Is There a Thaw?
Kinda, but not really. Wednesday sees us climb back to 35°F, but the overnight low stays brutal at 14°F. By Thursday, January 22, the snow returns. We’re tracking light snow all day with a 35% chance of precipitation and a high of 37°F.

The rest of the 10-day stretch stays pretty consistent with what we expect from a Jersey January:
- Friday, Jan 23: Partly sunny, high of 32°F, low of 25°F.
- Saturday, Jan 24: Partly sunny, high of 32°F, low of 25°F.
- Sunday, Jan 25: Partly sunny, high of 26°F, low of 18°F.
- Monday, Jan 26: Partly sunny, high of 23°F, low of 16°F.
What This Forecast Actually Means for You
Most people see "partly sunny" and think they can relax. In Montclair, that usually means the wind has a clear path to hit you even harder. With winds staying between 6 mph and 12 mph for most of the week, wind chill is the real story here.

Experts like Paul Pastelok from AccuWeather have been pointing to this southward dip in the jet stream for weeks. It’s creating a "buckle" that just keeps dumping cold air right onto the Garden State. While the Old Farmer’s Almanac predicted a milder winter overall, this specific 10-day window is clearly the "winter punch" they warned about for late January.
Actionable Prep for the Next 10 Days
- Salt your walk now. Don't wait for Sunday night's 23°F freeze to turn Saturday's slush into a skating rink.
- Check your tire pressure. These massive temperature swings from 37°F down to 13°F will make your "low pressure" light pop on faster than you can say "Park Street."
- Plan for delays. The snow on the 17th and 22nd isn't deep, but in Montclair, a half-inch of snow usually means a twenty-minute delay on the DeCamp bus or the NJ Transit Montclair-Boonton line.
- Layering is key. You need a wind-resistant outer shell for Monday and Tuesday. That 14 mph wind at 22°F is no joke.
The 10 day weather forecast montclair nj shows a classic, grueling stretch of January weather. Keep the shovel by the door and your heavy socks at the top of the drawer. You’re going to need them.
