You’ve seen the alerts. Maybe you even got a notification on your phone from the DSNY about "New York’s Strongest" hitting the streets with salt spreaders. Honestly, trying to pin down the ten day weather NYC experts track is like trying to catch a subway train that’s "delayed due to train traffic ahead." You know it’s coming, but the timing is always a mess.
Right now, New York is sitting in a weird, slushy limbo. Today, Saturday, January 17, we’re looking at a high of 39°F. Not exactly T-shirt weather, but not "frozen tundra" either. The humidity is hanging around 58%, and if you look out the window, it's basically just gray. That "light rain" the apps are screaming about? It’s actually got an 83% chance of being snow during the day. But here’s the kicker: because it’s 39 degrees, most of that won't even stick to the pavement. It’s that annoying, wet NYC slush that ruins your suede boots.
The Polar Vortex Is Actually Coming This Time
People throw around the term "Polar Vortex" like it’s a buzzword for every cold breeze. But the current ten day weather NYC outlook shows a real lobe of Arctic air sliding down from Canada.

Expect Sunday to be the pivot point. While today is 39°F, Sunday’s high is going to struggle to get out of the 20s. That’s a massive drop. By Monday, January 19—which is Martin Luther King Jr. Day—the city is going to feel like a wind tunnel. We’re talking wind gusts hitting 30 to 40 mph. If you’re planning on going to a parade or just grabbing a bagel, wear the heavy wool socks.
The real "fun" starts Tuesday. The lows are projected to hit the teens. When you factor in the wind chill, it’s going to feel like single digits. This isn't just "chilly." This is the kind of cold that makes your face hurt after three blocks of walking.

Why the Forecast Keeps Shifting
Weather in Manhattan is notoriously fickle because of the "urban heat island" effect. All those skyscrapers and concrete trap heat, which is why it might be snowing in White Plains while it's just a miserable drizzle in Times Square.
- The Saturday Storm: A quick-moving system. It should be wrapping up by 5 p.m. today.
- The Sunday Coastal Low: This is the one to watch. It’s tracking near the coast. If it stays east, Long Island gets buried and the city gets a dusting. If it nudges west? Monday morning's commute becomes a nightmare.
- The Mid-Week Freeze: Dry but brutal. No snow expected Tuesday or Wednesday, just pure, unadulterated cold.
Honestly, the "January Thaw" we had earlier this month is officially dead. We are entering the harshest stretch of the winter. According to the National Weather Service, this cold snap could last through the end of the month.

Survival Steps for the Next 10 Days
Don't be the person caught in a light denim jacket when the wind picks up on Monday.
- Check the DSNY updates. They’ve already warned that while trash collection is normal for now, Monday (MLK Day) has no pickup. If it snows more than expected, those delays will stretch into Tuesday.
- Salt your stoop tonight. Even if it’s just "light rain" now, that 33°F low tonight means everything turns into a skating rink by 6 a.m. tomorrow.
- Layering is a science. You need a base layer that wicks moisture. Sweat is your enemy in 15-degree weather because it turns cold the second you stop moving.
- Pet safety. If the pavement is too cold for your hand, it’s too cold for their paws. Keep the walks short once we hit that Tuesday deep freeze.
Basically, the next ten days are a classic New York winter gauntlet. A bit of slush, a lot of wind, and a legitimate Arctic blast that'll make you question why you don't live in Florida. But hey, at least the subway is warm. Usually.
