You’ve seen the forecast. It looks pretty standard for Rockland County in January, but if you’ve lived around here long enough, you know the weather forecast Monsey NY puts out isn't always what hits the ground at your front door. It’s early 2026, and the air is biting. Honestly, Monsey has this weird habit of playing by its own rules compared to nearby New York City.
Right now, we are looking at a messy mix. As of Thursday, January 15, the thermometer is hovering around 40°F, but the wind is kicking up from the west at about 11 mph, making it feel more like 34°F. That’s the classic Monsey "RealFeel" trap. You look out the window, see the sun, and think a light jacket is fine. Big mistake.
By tonight, things are going to get genuinely cold. We’re talking a low of 21°F. If you have sensitive pipes or plants that somehow survived the December frost, tonight is the night to be careful. The sky will be clear with just a few periodic clouds, which sounds nice, but it basically means all the heat from the day is going to vent straight out into space.
The Snow Problem and What to Expect
Tomorrow, Friday, January 16, is when it gets interesting. We’re looking at a high of 34°F. That’s right on the edge. The forecast says flurries in the morning followed by snow showers at night. The chance is only about 25%, but in this part of the state, that’s often code for "slippery sidewalks on your way to Shul or the store."
Saturday isn't looking much better. We’re expecting more snow showers with a slightly higher probability of 35%. Temperatures will bounce between a high of 38°F and a low of 28°F.

Here’s the thing about Monsey weather: we’re tucked into a spot where the humidity stays high—currently around 73%—which makes the cold feel damp and heavy. It’s not that crisp, dry mountain cold you get further north. It’s the kind of cold that finds the gap between your scarf and your coat.
Why Monsey Isn't Just "Upstate Lite"
A lot of people think the weather forecast Monsey NY gets is basically the same as the city. It isn't. Not even close. We sit in a transition zone. According to the Köppen Climate Classification, we’re technically in a Humid Continental (Dfa) zone. This means we get the full brunt of hot, muggy summers and winters that can be, frankly, brutal.
Unlike the city, which is a massive "urban heat island" made of concrete and asphalt, Monsey has more open space and suburbs. This means we are often 5 to 7 degrees colder than Manhattan at night. When the city gets rain, we get sleet. When they get sleet, we get three inches of heavy, wet snow.
Looking Ahead: The Deep Freeze
If you think this week is chilly, brace yourself for Monday and Tuesday. We are heading into a serious temperature drop.

- Monday, Jan 19: High of 31°F, Low of 11°F.
- Tuesday, Jan 20: High of 19°F, Low of 11°F.
A high of 19°F is no joke. The wind is expected to stay around 13 mph from the west, so the wind chill will likely be in the single digits or even negatives. This isn't just "inconvenient" weather; it's "check-on-your-elderly-neighbors" weather.
Historically, January is our coldest month for a reason. Records from sites like WeatherSpark and the National Weather Service show that the average daily high is usually around 36°F. We’re currently trending slightly warmer than that for the next few days, but the crash coming next week will bring us right back to reality.
Specific Hazards for Monsey Residents
One thing nobody talks about enough is the ice. Because we have so many hills and small side streets, "black ice" is a massive factor here. The current cycle of 40°F days and 20°F nights is the perfect recipe for it. Snow melts during the day, runs across the road, and flash-freezes into a glass-like sheet the second the sun goes down.
If you’re driving near Route 59 or along the Main Street corridors, keep an eye on the pavement that looks "wet" after dark. It probably isn't water.

Practical Steps for the Next 48 Hours
Instead of just checking the app every five minutes, there are a few things you should actually do.
First, salt your walkways now. Don't wait for the Friday flurries. Putting a base layer down prevents the snow from bonding to the concrete.
Second, check your car's tire pressure. Cold air causes the air inside your tires to contract, and you’ll likely see that annoying "low pressure" light pop up on your dashboard tomorrow morning.
Third, dress in layers. Since the high/low swing is nearly 20 degrees today, you need a moisture-wicking base and a wind-resistant outer shell.
Lastly, keep an eye on the Saturday night forecast. While the accumulation is predicted to be low (less than an inch), the timing of the snow showers could make for a messy Sunday morning.
Stay warm, stay safe, and remember that even if the weather forecast Monsey NY looks clear, the wind coming off the Hudson Valley always has the final say. Check your heating oil levels if you aren't on gas—you don't want to run dry when that 19-degree Tuesday hits.
