Honestly, looking at the sky over the Susquehanna today, you'd think winter was just playing a game of "wait and see." It’s cloudy. It’s grey. It feels like every other January afternoon in Central PA. But if you’re actually planning your week—maybe thinking about that commute down I-83 or wondering if the kids will finally get a real snow day—the 10 day forecast harrisburg pa has some pretty sharp teeth that aren’t immediately obvious.
Right now, we're sitting at a crisp 31°F. Not unbearable, right? But with that northwest wind kicking at 9 mph, the "feels like" is a much more bitey 23°F. It’s that classic Harrisburg damp cold that settles in your bones.
The Deep Freeze is Coming
The next few days are basically a slow slide into a deep freezer. While Monday, January 19, holds onto a high of 32°F, the bottom falls out at night. We’re looking at a low of 9°F. Yeah, single digits. If you haven't checked your tire pressure or your outdoor spigots, do it now.

By Tuesday, January 20, the sun might be out, but it's a "fake" sun. The high won't even crack 20°F. Combined with an 11 mph wind, you're going to want the heavy parka, not the light fleece.
Mid-Week Fluctuations
Mid-week gets a little weird. We see a tiny "warm-up" on Thursday, January 22, hitting 42°F. It’s the kind of day where the slush from previous dustings turns into a muddy mess before freezing solid again.

- Wednesday (Jan 21): Mostly cloudy, high of 35°F, low of 12°F.
- Thursday (Jan 22): Sunny breaks, high of 42°F. Watch for black ice that night as it drops to 23°F.
- Friday (Jan 23): Light snow chances return with a high of 34°F.
The Real Snow Threat
If you're a snow lover (or hater), keep your eyes on the weekend of January 25 and 26. The 10 day forecast harrisburg pa shows a significant shift here. Monday, January 26, is currently pegged for a 65% chance of actual snow during the day. This isn't just "flurries" or a "wintry mix"—the data suggests enough moisture and cold air to actually stick.
Highs during that period will struggle to stay in the low 20s. Sunday night into Monday morning looks particularly tricky for anyone heading into work downtown or toward the Capitol Complex.

Survival Tactics for the Next 10 Days
Basically, don't let the 40-degree Thursday fool you into thinking winter is softening up. We are heading into the heart of the coldest stretch of the month.
- Check the Lows: The daytime highs are manageable, but the overnight lows (8°F to 9°F) are where pipes burst.
- Wind Direction: Most of our cold is riding in on northwest and west winds. If your house has a lot of north-facing glass, you'll feel that draft.
- Monday Prep: Since January 26 has the highest precipitation probability (65%), make sure you have the salt and the scraper ready on Sunday night.
The UV index is staying at a flat 0 or 1 for almost this entire stretch, so don't expect the sun to do any heavy lifting when it comes to melting ice on your driveway. What stays, stays.
Keep the heavy blankets near the couch. This 10-day stretch is essentially Central Pennsylvania reminding us exactly what month it is. Stay warm out there.
Actionable Next Steps:
Stock up on ice melt before the Thursday thaw-and-freeze cycle, and ensure your vehicle's antifreeze is rated for the single-digit temperatures hitting Monday and Tuesday nights.
