Right now, if you step outside in Yorktown Heights, you’re hitting a wall of damp, 28°F air. It’s cloudy, kind of quiet, and feels exactly like the calm before a Hudson Valley storm. Honestly, everyone talks about the "Goldens Bridge commute" or the hills of FDR Park, but nobody really prepares for how fast the mercury drops once you get past the Croton Reservoir.
Today—Sunday, January 18, 2026—is basically a textbook example of Westchester winter mood swings. We’re sitting at 28°F with a 2 mph breeze coming out of the southwest. It feels still, but the humidity is high at 84%. That’s the kind of air that bites into your bones even when the wind isn't howling.
The Sunday Snow Situation
If you've got plans to head down to the Heights or grab a coffee near the triangle, keep an eye on the sky. The forecast for the rest of today is calling for snow. We aren't talking about a massive blizzard, but it’s enough to make the local roads slick.
The daytime high is expected to reach 33°F, just barely hitting that freezing mark. There’s a 35% chance of snow during the day. As we move into tonight, that chance actually bumps up to 45%. It’ll transition into a light snow, and the temperature is going to tank down to 17°F.
The wind is also shifting. Expect a 6 mph northerly wind to kick in, which is going to make that 17°F feel a lot more like single digits.
Why Yorktown Isn't Just "NYC Weather"
There’s this common misconception that if it’s raining in Manhattan, it’s raining in Yorktown Heights. Total myth. Because we’re tucked into the Northern Westchester hills, we often deal with "micro-climates."
While the city might stay at a slushy 38°F, the elevation in Yorktown keeps us just cold enough to turn that rain into ice or a few inches of accumulation. Historically, January is our coldest month for a reason. We usually see average lows around 21°F, but as we’re seeing tonight, 17°F isn't exactly a rare guest.
The humidity is the real kicker here. At 92% projected for the day, it's a "wet cold." It’s the reason your car windshield is probably going to be a sheet of ice tomorrow morning even if the snow totals are low.
What the Numbers Actually Mean for You
- Current Temp: 28°F (Cloudy)
- Today's High: 33°F (Snow likely)
- Tonight's Low: 17°F (Light snow)
- Precipitation Chance: 35% day / 45% night
- Wind: North at 6 mph (tonight)
Surviving the January Slump
People around here are used to it, but Yorktown winters require a specific kind of local knowledge. The salt trucks usually do a decent job on Route 202 and 118, but the backroads near Turkey Mountain get treacherous fast.
Since the UV index is a flat zero today, don't expect any "sun-melt" to help clear your driveway. Whatever falls is likely staying until the next warm front. If you're heading out, the Southwest wind we have right now is gentle, but that shift to the North tonight is the signal to bring the pets inside and double-check the heater.
Basically, it’s a standard mid-January Sunday. A bit of snow, a lot of cold, and that classic Westchester grey sky.
Actionable Next Steps
- Check your tires now: With the temperature dropping to 17°F tonight, any moisture on the ground will turn into black ice by 9:00 PM.
- Clear the slush: If we get that 35% daytime snow, shovel it before the sun goes down. Once it hits 17°F, that slush becomes concrete.
- Prepare for a "feels like" in the teens: When the wind picks up from the North tonight, the "real feel" will be significantly lower than the actual 17°F reading.
