Honestly, if you're standing outside in York right now, you already know the vibe. It’s cold. Like, "don't forget your gloves on the dashboard" cold. As of late Saturday night/early Sunday morning, January 18, 2026, the mercury in York is sitting right at 31°F. It’s basically hovering at that freezing point where the air feels heavy, damp, and just a bit sharp.
The sky is a solid sheet of clouds. No stars tonight.
We’ve got a light breeze coming out of the east at about 3 mph, which sounds like nothing, but in 31-degree weather? It’s enough to make you zip the coat all the way up. Humidity is pretty high at 79%, which is why the air feels "wet" even though it’s not currently dumping snow on us.
The York PA weather now situation is kinda tricky
Yesterday was a mess. You probably saw the reports or were stuck in the thick of it—dozens of crashes across York and Lancaster counties. A fast-moving snowstorm on Saturday morning turned I-76 and I-81 into skating rinks. Nate Soisson over at FOX43 was tracking the chaos, and at one point, York County Dispatch had to operate under emergency circumstances just to keep up with the volume of calls.
Today, Sunday, isn't going to be a total repeat of that drama, but it's not exactly "t-shirt weather" either.
What to expect for the rest of Sunday
- Morning Snow: There’s a 45% chance of light snow during the day. We aren't looking at a blizzard, but enough to make the sidewalks slick again.
- The High: We’re topping out at 32°F. That is literally the freezing mark. Everything that melts for a second is going to turn into a thin sheet of ice the moment the sun starts to dip.
- The Low: Tonight is going to be brutal. The temperature is forecasted to tank down to 17°F.
- Wind: Expect the wind to shift and pick up a bit, coming from the northwest at 10 mph.
If you’re planning on heading out to the Central Market or just taking the dog for a walk around Cousler Park, just know that the "cloudy" condition we have right now is likely to stick around until the sun goes down.
Why this January feels different
People keep talking about how this winter feels "off." They're not wrong. While the long-term averages for York in January usually see highs around 38°F, we’re currently trending a bit lower. The Old Farmer’s Almanac actually predicted this—calling for a January that’s about 2 degrees below average for the Appalachians region.
We are currently in a "very cold" stretch that’s supposed to last through the 22nd.
Kinda weirdly, even though it's freezing, the total precipitation for the month is actually expected to be below normal. We’re getting these "clipper" systems—fast, dry, and cold—rather than the big, wet Nor’easters that dump two feet of powder and shut down the city for three days. It's more of a persistent, annoying cold than a historic snow year.
The "False Spring" risk
Looking at the data from MARISA (the Mid-Atlantic Regional Integrated Sciences and Assessments), York is actually seeing a long-term trend of shifting seasons. Our winters are getting shorter, but they're getting more erratic. We get these weird "false springs" where it hits 55°F in February, the buds start to pop on the trees, and then—bam—an Arctic blast hits and kills everything.
Right now, we are definitely in the "Arctic blast" part of that cycle.
Real talk: Driving in South-Central PA today
Look, after Saturday's pile-ups on PA 97 and near the exits on the interstate, local authorities are on high alert. Even if it’s just "light snow" today, the ground temperature is already cold enough for it to stick instantly.
- Watch the bridges: The ones over the Codorus Creek always freeze first.
- Check the wind: A 10 mph northwest wind might not sound like much, but it creates "black ice" patches by flash-freezing any moisture on the asphalt.
- MLK Day Forecast: Tomorrow (Monday) looks mostly sunny with a high of 34°F, but don't let the sun fool you. The low Monday night is expected to hit 10°F.
Basically, the next 48 hours are about survival and salt. If you haven't restocked your rock salt or checked the air pressure in your tires, now is the time. Cold air makes tire pressure drop, and nobody wants to be changing a flat on the side of Route 30 when it's 17 degrees out.
Your immediate next steps
Check your tailpipe if you're idling your car to warm it up—snow buildup can cause carbon monoxide issues. Also, if you have outdoor pets, bring them in. A 17-degree low is dangerous for any animal left outside overnight. Stay warm, keep the de-icer handy, and maybe just stay off the roads this evening if the snow starts to pick up again.
