Pittsburgh winters are a special kind of chaotic. One day you’re walking the Three Rivers Heritage Trail in a light hoodie, and the next, you’re digging through the hall closet for that heavy wool parka you swore you wouldn't need yet. Honestly, if you've lived here long enough, you know the drill.
The weather for sunday in pittsburgh is looking like a classic reality check for anyone who got too comfortable with those weirdly warm spikes we had earlier in the month.
We’re talking about Sunday, January 18, 2026.
It’s going to be cold. Like, "don't leave the house without gloves" cold.
What the Sunday Forecast Actually Looks Like
The National Weather Service out in Moon Township is tracking a pretty significant dip. We're looking at a high of only 24°F or 25°F. Compare that to the 60-degree weather we saw just a week or so ago, and it’s a total system shock.

The low? Somewhere around 15°F.
Basically, the "January Thaw" is officially over.
You’ll wake up to mostly cloudy skies, though there’s a decent chance of seeing some "partly sunny" peeks throughout the afternoon. Don't let the sun fool you, though. A steady west wind at about 10 to 11 mph is going to make that 24 degrees feel significantly sharper on your face.
Will it snow on Sunday?
Snow is the big question every weekend in January. Right now, there is a 20% chance of light snow during the day. It’s not looking like a "bread and milk" emergency. You probably won't need the heavy-duty salt for your sidewalk, but a light dusting or some flurries are definitely on the table.

If you are heading into the Laurel Highlands or out toward Fayette County, keep an eye out. Those higher elevations always catch the brunt of the lake-effect moisture that misses the city.
Planning Your Sunday Around the Chill
Even with the freeze, Pittsburgh doesn't just stop. There’s actually a ton happening if you’re willing to brave the walk from the parking garage to the venue.
- Locomotion Weekend at Kamin Science Center: This is a huge hit for families. It’s indoors, obviously, which makes it the perfect refuge for Sunday. They have massive model train layouts that take over the building.
- Pittsburgh Restaurant Week: This is still rolling through Sunday. It's a great excuse to grab a table at places like Masala House Indian Bistro or somewhere downtown where the "winter comfort food" menus are in full swing.
- Frick Winterfest: If you’re at The Frick, just be ready. Most of the magic is at the museum, but walking the grounds will be biting.
The "Gray Sky" Factor
We have to talk about the clouds. Pittsburgh is notoriously one of the cloudiest cities in the country during January. Sunday is going to have that typical gray ceiling for a good portion of the day.
For a lot of us, that "Steel City Gray" can be a bit of a mood killer. Local experts and even folks on the Pittsburgh subreddit often suggest leaning into it. Hit up Phipps Conservatory—the tropical forest room is basically a "cheat code" for surviving 24-degree weather.

Travel and Road Conditions
Since the temperatures are staying well below freezing all day, any moisture that does fall will stick.
The 20% precipitation chance is low, but in Pittsburgh, "light snow" can quickly turn into "slick bridges." Watch the ramps on I-279 and the Highland Park Bridge. They freeze way faster than the actual road surfaces.
Honestly, the wind is the bigger story for Sunday. If you're planning on ice skating at the UPMC Rink at PPG Place, that wind whipping between the glass skyscrapers is going to be brutal.
Actionable Tips for Sunday
- Layer up properly: Don't just wear one big coat. Wear a moisture-wicking base, a fleece or sweater, and then your windbreaker or parka. The wind will cut right through a single heavy knit.
- Check your tires: These 40-degree temperature swings cause tire pressure to plummet. If your "low air" light wasn't on yesterday, it might be on Sunday morning.
- Go early for indoor events: Places like the Kamin Science Center will be packed because everyone is trying to escape the cold.
- Support local: Sunday is a big day for the tail end of Restaurant Week. Make a reservation now, because the "dinner and a movie" crowd will be looking for indoor escapes.
The cold is settling in for the long haul now. Monday looks even colder with highs barely hitting 23°F and lows potentially dropping into the single digits. Enjoy the "warmth" of 25 degrees while you can.
