You've probably seen the headlines. "Arctic Blast Incoming!" or "Snowmageddon Part 12." Honestly, if you live in New York, you know that the weather forecast NYC 15 days out is basically a coin toss. But right now, we’re looking at a stretch of January that’s actually making the meteorologists sweat.
We aren't just talking about a little frost on your windshield.
The data for mid-to-late January 2026 shows a city caught between a lingering Canadian chill and a series of moisture-heavy fronts. It's messy. It's cold. It's New York.
Why the weather forecast NYC 15 days out is so weird right now
Kinda weird, right? One day it's 38°F and raining, the next you're looking at a low of 7°F.
On Saturday, January 17, we started with light rain and a high of 38°F. That's the deceptive part of a New York winter. It feels mild until the sun goes down and that southwest wind at 9 mph starts biting through your layers.
But look at the shift coming. By Sunday, January 18, we’re moving into snow showers with a high of only 34°F. That’s a total flip-flop in less than 24 hours. The real kicker? Monday night and Tuesday are when the "Canadian air" really checks in.

We are talking about a massive drop. Tuesday, January 20, is projected to hit a high of only 23°F. The low? 14°F.
If you think that’s cold, just wait until Sunday, January 25. The forecast is calling for a low of 7°F. Seven degrees! That’s significantly below the typical January average for Central Park, which usually hovers around a low of 29°F.
The Mid-Week Tease
New Yorkers love to complain about the "tease" days.
Take Thursday, January 22. The mercury is supposed to climb back up to 41°F. You might even think about leaving the heavy parka at home. Don't.
Even with a "balmy" 41°F, the wind is expected to be coming from the southwest at 15 mph. In the canyons of Manhattan, that’s going to feel like a wind tunnel. Plus, the low that night drops right back down to 20°F.

Snow, Rain, or That Weird Slushy In-Between?
Basically, the next two weeks are a grab bag of precipitation.
- Today (Jan 17): 90% chance of rain/snow mix.
- Tomorrow (Jan 18): 45% chance of snow showers during the day.
- Next Monday (Jan 26): We’re looking at another round of snow showers with a high of 20°F.
The National Weather Service has been tracking a "clipper storm" moving across the Great Lakes. For us in the city, that usually means light snow and gusty winds rather than a massive blizzard, but it’s enough to make the Monday morning subway commute a nightmare.
Current humidity levels are sitting around 67%, which is why the air feels so heavy and damp. It's that bone-chilling cold that denim can't stop.
Handling the 7°F Reality Check
When the temperature hits single digits like what’s projected for January 25, the "Feels Like" temperature is the only number that matters. With northwest winds hitting 16 mph that day, the wind chill will likely be well below zero.
It’s the kind of weather where your phone battery dies in ten minutes if you leave it in an outer pocket.

Actionable Tips for the Next 15 Days
Stop checking the app every five minutes and just prepare for the worst of it.
First, if you're commuting, Monday, January 19 and Tuesday, January 20 are the "deep freeze" days. Dress in three layers—not two. A base layer of wool or synthetic is non-negotiable when the high is only 23°F.
Second, watch the ice on Wednesday, January 21. We have a low of 14°F the night before, and even though it's partly sunny, the melt-and-refreeze cycle on New York sidewalks is a literal death trap.
Finally, check your windows. If you’re feeling a draft now when it’s 37°F, you are going to be miserable when it hits 7°F next Sunday. Heavy curtains or even the "towel under the door" trick can save you a fortune on your ConEd bill this month.
Stay warm. It's going to be a long two weeks.
