So, if you looked out the window this morning in Lancaster, you probably saw exactly what the forecasters were nervous about. It's messy. Honestly, it’s that classic Central PA winter mix where the sky can’t quite decide if it wants to be a snow globe or a car wash.
Right now, a Winter Weather Advisory is officially in effect until noon today, January 17, 2026. If you’re living anywhere between Elizabethtown and Gap, you’ve likely seen the flakes already piling up. We aren’t talking about a "stock up on three weeks of milk" kind of storm, but it's enough to make the Saturday morning grocery run a total pain. The National Weather Service out of State College is calling for 1 to 3 inches of snow across the county, potentially mixed with a nasty little glaze of ice or sleet.
What's Happening Right Now?
Basically, we have this low-pressure system dragging itself across the Great Lakes, paired with a shortwave disturbance moving right over the Susquehanna Valley. It’s a bit of a "one-two punch" situation. The first round of light snow hit overnight, and now we’re in the thick of the steady, accumulating stuff.
Temperature-wise, it’s hovering right around 30°F, but with that south wind kicking at about 8-9 mph, it feels more like 22°F. It’s biting. The high for today might struggle to hit 39°F, which means whatever falls this morning is going to stick to the untreated backroads and side streets.

Why the Next 48 Hours Get Weird
Here is the thing about Lancaster PA weather news that usually gets buried in the headlines: it’s not just the snow; it’s the flash freeze risk.
By this afternoon, the snow should taper off, and we might even see some "partly sunny" breaks in the clouds. Don't let that fool you. As the clouds break, road temperatures can actually rise a bit, melting that slush. But tonight, the mercury is going to drop back down to about 30°F, and tomorrow (Sunday) we’re looking at a high of only 31°F. Anything that’s wet on the ground today is going to be a sheet of glass by tomorrow morning.
- Today (Saturday): Snow/mix early, high of 39°F.
- Sunday: Brisk, chance of snow showers, high of 31°F.
- Monday: Sunny but deceptive. The arctic hammer arrives.
The Real Story: Monday's Arctic Blast
If you think today is cold, just wait until Martin Luther King Jr. Day. While the sun will be out, we are looking at a serious arctic blast that’s going to make the early part of next week feel like the North Pole.

Monday night is when it gets truly dangerous. We’re talking about lows around 10°F, with wind chill values potentially dipping to 5 below zero. If you have outdoor pets or pipes that like to freeze, Monday is your deadline to get that sorted. Tuesday doesn't get much better, with a projected high of only 22°F. That’s the kind of cold that hurts your face the second you step out of the house.
Safety and Travel
PennDOT has already been out pre-treating the major veins like Route 30 and 222, but the local emergency management is still urging caution. The "Red Rose Alerts" system—which if you haven't signed up for, you probably should—has been pinging with updates about slippery conditions.
The big worry for the NWS isn't just the 1-3 inches of accumulation today; it's the snow squalls possible late Saturday afternoon. These are those sudden, blinding bursts of snow that can drop visibility to near zero in seconds. If you're driving and the sky suddenly turns white, pull over. It’s not worth it.

Actionable Next Steps for Lancastrians
Look, we’ve done this before, but every winter we forget the basics. Here is what you actually need to do before the sun goes down today:
- Check the salt pile: If you used up your stash during that light dusting earlier this month, get more now. You’ll need it to prevent ice from the Saturday afternoon melt.
- Prep for Tuesday’s cold: Ensure your car battery is in good shape. Sub-zero wind chills are notorious for killing older batteries right when you need to get to work.
- Monitor the "Boil Water" situations: While Lancaster City is fine, keep an eye on regional news. Recent infrastructure strain in nearby counties (like the recent disaster declaration in Carbon County) reminds us that extreme cold puts massive stress on municipal pipes.
- Download the 511PA app: Seriously. It gives you the live feed of plow locations and road speeds. It’s way more accurate than just guessing based on your neighbor's driveway.
Winter in the Susquehanna Valley is always a bit of a gamble, but staying ahead of the "freeze-thaw-freeze" cycle is the only way to keep your car out of a ditch on Route 283. Stay warm, stay off the roads if you can this morning, and get ready for that deep freeze on Monday.
