Honestly, if you're living in Chambersburg right now, you’ve probably spent the morning wondering if the sun is ever coming back. It's Friday, January 16, 2026, and looking out the window reveals a sky that's basically just one giant gray blanket.
Current conditions are sitting at exactly 30°F. But here is the thing: it feels more like 21°F because of that 10 mph wind coming out of the south. If you’re heading out to Memorial Park or just grabbing coffee downtown, that wind chill is going to bite. We've got a humidity level of 32%, which is actually pretty dry for a winter day in PA, but the 10% chance of snow flurries means you might see a stray flake or two before the day is out.
The 10 day forecast for chambersburg pa looks like a classic Mid-Atlantic January rollercoaster. We aren't seeing any massive "Snowmageddon" events on the immediate horizon, but the temperatures are definitely going to keep you on your toes.

Is Snow Actually Coming?
Most people in Franklin County start getting twitchy about snow this time of year. Looking at the data for the next week and a half, the biggest "risk" day appears to be Sunday, January 25.
We are tracking a 35% chance of snow showers during the day and a 25% chance at night. With a high of 33°F and a low of 17°F, conditions are just right for things to actually stick if the moisture holds up. Before that, Wednesday and Thursday (Jan 21-22) show some clouds and maybe a 10-20% chance of flurries, but nothing that should require a shovel.
Living With the Chambersburg Chill
Historically, January is our cloudiest month. Data from places like Wanderlog and WeatherSpark shows that we usually deal with overcast skies about 54% of the time. This 10-day stretch is sticking right to that script.
If you are a fan of the "January Thaw," you might find some comfort in next Saturday, January 24. We're looking at a high of 38°F. It’s not exactly t-shirt weather, but it’s a lot better than the 20-degree highs we'll see earlier in the week.
Honestly, the real story here is the wind. Between now and next Friday, wind speeds are going to hover between 3 mph and 15 mph. That western wind on Monday is going to be the sharpest. If you're out walking the dog, those 15 mph gusts will make that 30-degree high feel significantly colder.
Actionable Survival Tips for the Next 10 Days
- Prep for Monday Night: With a predicted low of 10°F on Monday and Tuesday, make sure your outdoor faucets are covered and your pets are indoors. That kind of cold isn't just "chilly"—it's pipe-bursting territory.
- Saturday Travel: If you’re traveling on Saturday, Jan 17, keep an eye on the 20% precipitation chance. It's low, but with a low of 27°F, any afternoon rain could easily turn into slick spots on the backroads as evening hits.
- Layer Up for the Sun: Don't let the sunny forecast for Monday and Tuesday fool you. Those are going to be some of the coldest days of the month. A windbreaker over a heavy fleece is your best friend here to block that 15 mph western wind.
- Watch Sunday the 25th: This is the only day with a precipitation chance over 30%. If you have a long commute or travel plans, check the local radar on Saturday night to see if that snow shower chance has trended upward.
Stay warm out there, Chambersburg. We've got a lot of gray days ahead, but at least the sun is scheduled to make a cameo appearance at the start of the work week.
