Honestly, if you've lived in Western New York for more than a week, you know the drill. You check the app, see a snowflake icon, and shrug. But weather for buffalo on sunday, January 18, 2026, isn't just a "business as usual" winter day. It’s a bit of a psychological game.
We’re looking at a high of 22°F.
The low? 18°F.
That’s a four-degree spread. It’s basically a flat line on the thermometer. When the temperature stays that tight, the air feels heavy, almost static.
The Lake Erie Factor
Most people think "snow showers" means a light dusting that disappears by noon. In Buffalo, that’s a dangerous assumption. According to the latest data, we have a 25% chance of snow showers during the day, which jumps to 35% at night.
Those numbers seem low, right?
Kinda.
But you have to look at the wind. We’re expecting a steady 15 mph pull coming straight from the southwest. For those of us in the Southtowns or near the harbor, that southwest wind is the classic "Lake Effect" delivery service. It picks up moisture from Lake Erie—which is still relatively warm this year—and dumps it in concentrated bands.
Why Sunday Feels Different
The humidity is hovering at 75%. That’s the "bone-chilling" kind of cold. It’s the moisture that finds the gap between your scarf and your jacket. With a UV index of 0, don't expect the sun to help you out. It’s going to be a grey, overcast ceiling all day long.
Experts like the meteorologists at the National Weather Service often talk about the "inversion height," but basically, for us on the ground, it just means the clouds are sitting low and heavy.
I was chatting with a neighbor yesterday who’s lived on Elmwood for forty years. He calls these "sneaky Sundays." You think you’re just going out for a quick coffee at Spot, and suddenly you’re brushing three inches of fresh powder off your windshield because a small cell sat over your zip code for forty-five minutes.
That’s the nuance of Buffalo winter. It’s local. It’s specific.
What to Actually Do
If you're planning to head to a game or just run errands, Sunday is the day for layers, obviously. But specifically, focus on windproofing. A 15 mph wind at 22°F creates a wind chill that feels significantly lower than the actual temp.

- Check the radar every hour. Don't trust the morning forecast to hold for the afternoon.
- Watch the southwest wind. If you're driving on the I-90, that crosswind can get twitchy, especially with patchy snow.
- Top off your fluid. Winter mix washer fluid is your best friend when the salt spray starts hitting the glass.
The reality of weather for buffalo on sunday is that it’s a transition day. We’re coming off a slightly warmer Saturday and heading into a colder Monday. It’s the bridge.
Don't let the 25% precip chance fool you into leaving the shovel in the garage. In Buffalo, 25% is often just enough to make the driveway a mess right before you have to leave for work on Monday morning.
Keep an eye on the lake. Stay warm.
