Honestly, if you've lived in Bucks County for more than a single winter, you know the drill. You check the Newtown PA weather forecast on a Friday night, see a few snowflakes on your app, and think nothing of it. Then you wake up on Saturday morning to a town transformed into a literal snow globe.
That's exactly where we are right now. It's Friday night, January 16, 2026, and the air has that specific, heavy stillness that usually means something is coming. Currently, it's a crisp 31°F outside, but with a light south wind at 5 mph, it feels more like 25°F. If you’re heading out to State Street for a late dinner, definitely grab the heavy coat.
The clouds are already settled in, and they aren't going anywhere.
The Immediate Outlook: Snow is Definitely on the Menu
We’ve got a busy weekend ahead for anyone who owns a shovel. Tomorrow, Saturday, January 17, is looking like the "main event" for this particular system. While the high will reach 37°F, don’t let that semi-mild number fool you. We’re looking at a 68% chance of snow during the day.

Usually, when the temperature hovers that close to the freezing mark, we get that heavy, wet slush that’s a total pain to clear. The South wind will pick up a bit to about 10 mph, making it feel just miserable enough to stay indoors.
Sunday isn't offering much of a reprieve either. We’re expecting snow showers to linger with a high of 33°F and a low of 19°F. The wind is going to shift to the northwest, which typically acts like a funnel for colder air coming down through the valley.
The Week Ahead: A Deep Freeze is Coming
If you think this weekend is cold, just wait until Tuesday. We are about to fall off a temperature cliff.

While Monday stays somewhat stable at 33°F, Tuesday, January 20, is going to be a shock to the system. We’re looking at a high of only 23°F and a low of 14°F. That is the kind of cold that makes your car engine groan when you turn the key.
Basically, the jet stream is doing its mid-January dance, pulling Arctic air directly over Pennsylvania. By the time we hit Wednesday and Thursday, we might see some light snow again, but the real story is the persistent freeze.
What the History Books Say
It’s easy to think this is unusual, but Newtown has a history of these mid-January thaws followed by brutal "Arctic Revenges." According to historical data from the National Weather Service and projects like MERRA-2, January is consistently our windiest and coldest month. The average high is typically around 38°F, so we’re actually trending a bit below the norm this year.

Interestingly, while some years are bone-dry, January 2026 is shaping up to be fairly active. We've already seen a mix of "lake-effect" leftovers and coastal disturbances hitting the I-95 corridor.
Survival Tips for the Newtown Freeze
Since we’re staring down a low of 7°F by next Monday night, now is the time to do the "boring" adult stuff you usually put off.
- Check your pipes. If you have a crawlspace or an unheated garage, make sure those lines are insulated.
- Salt early. Since Saturday’s snow is likely to be wet and then freeze solid on Sunday night, getting a layer of brine or salt down before the Saturday afternoon slush sets in will save your back later.
- The "Bucket" Trick. Keep a bucket of sand or birdseed in the car. It’s better than salt for emergency traction if you get stuck on one of those winding backroads near Tyler State Park.
The humidity is sitting around 51% right now, but as that snow hits tomorrow, it'll jump to 70%. That damp cold is the kind that "gets in your bones," as my grandmother used to say.
Looking further out, the Newtown PA weather forecast suggests we might see a slight "January Thaw" toward the very end of the month, but it’ll be a bumpy ride getting there. For now, keep the snow brush in the front seat and maybe double-check your heating oil levels.
Actionable Next Steps:
Keep a close eye on the Saturday morning radar. With a 68% chance of precipitation, the transition from "cloudy" to "snow-covered" will likely happen between 8:00 AM and 11:00 AM. If you have errands to run, do them tonight or very early tomorrow to avoid the inevitable mess on the Bypass.
