Honestly, if you've lived in the Summit City for more than a week, you know the drill. You check the app, see a snowflake, and suddenly everyone at the Kroger on North Clinton is fighting over the last loaf of bread. But the fort wayne weather forecast 10 day outlook isn't just about whether you'll need a shovel. It's about that weird, bone-chilling humidity and the wind that hits you like a freight train the second you step out of a TinCaps game or off the bus downtown.
Right now, we are looking at a classic Indiana January stretch. It's cold. Like, "don't leave your dog outside for more than two minutes" cold.
As of January 16, 2026, the current temperature is sitting at a crisp 17°F, but with that southwest wind kicking at 10 mph, it feels like 7°F. That’s the real number. The one that bites your nose.
The Immediate Outlook: Snow and Slush
If you’re looking at the next few days, Friday is the big one. We’re expecting snow showers with a high of 33°F and a low of 21°F. The chance of precipitation is pretty high at 59% during the day. Basically, expect a mess. The National Weather Service in Northern Indiana has already been talking about reduced visibility, especially south of US-30.

It’s not a blizzard. It’s a "clipper" system.
The lake effect snow that hit us a couple of days ago—where South Bend got buried under 17 inches while we only saw about an inch at the airport—was a reminder of how fickle Northern Indiana can be. For the next ten days, the pattern is: flurries, clouds, and a brief window of "mild" before the arctic air returns.
What the Next Week Actually Looks Like
- Saturday (Jan 17): Mostly cloudy and a high of 21°F. The wind switches to the west at 16 mph. It’s going to be a "stay inside and watch Netflix" kind of day.
- Sunday (Jan 18): High of 20°F with light snow. The low drops to 8°F.
- Monday (Jan 19): This is the day to watch. The high is only 9°F. Yes, single digits. The low? 2°F. With 20 mph winds from the west, the wind chill will be dangerous.
- Midweek (Jan 20-22): We bounce back slightly. Tuesday sees 29°F with more light snow, and Wednesday stays around 29°F with a steadier snow chance.
Why the 10-Day Forecast Is Hard to Nail
People always complain that the weathermen are wrong. But here’s the thing about Fort Wayne: we are stuck in a weird geographic pocket. We get the moisture from the Great Lakes, but we don’t always get the "big" snow because we’re just far enough south.
Instead, we get ice. Or that weird "graupel" that looks like Dippin' Dots but feels like gravel hitting your windshield.
According to historical data from the MERRA-2 project and local observations at KFWA (that's the airport code for the non-weather geeks), January is our cloudiest month. We only get about 8.2 hours of clear skies on a typical day. It’s gray. It’s very gray.
Humidity and Your Wardrobe
Most people forget that Fort Wayne is actually quite humid in the winter. We’re looking at an average relative humidity of around 83% today. When it’s 20 degrees and 80% humidity, that cold "sticks" to you. A light puffer jacket won't cut it. You need a shell that blocks the wind and a base layer that wicks moisture.
Honestly, layering is the only way to survive a walk through Promenade Park right now.
Surviving the Single-Digit Dip
When Monday hits and that high of 9°F arrives, things get real. The "Bitterly Cold" thresholds set by experts like those at AccuWeather aren't just suggestions. At these temps, frostbite can happen to exposed skin in under 30 minutes if you aren't careful.
- Check your tires: Cold air makes tire pressure drop. That "low tire" light is going to haunt your dashboard this week.
- Drip the faucets: If you live in one of the older homes in '05 or '07, those pipes are vulnerable when it hits 2°F at night.
- Salt early: Don't wait for the snow to stop on Friday. A thin layer of salt before the 33°F daytime high drops to the 21°F nighttime low will prevent the "black ice" surprise on your driveway.
Looking further out toward the end of the month, the Old Farmer’s Almanac and long-range models suggest we might stay below average for a while. The 10-day trend doesn't show any "January Thaw" in the immediate future. We’re stuck in the freezer for the long haul.
Keep an eye on the wind direction. When it’s coming from the southwest, it’s usually bringing in a bit of moisture. When it shifts to the northwest, like it will later this weekend, that’s when the "Arctic Express" arrives.
Prepare for a gray, windy, and occasionally snowy week. If you're heading out to Glenbrook Square or just commuting down Lima Road, give yourself an extra ten minutes. The roads will be slicker than they look.
Actionable Next Steps:
Check your car's antifreeze levels today while it's still in the 30s. Ensure your emergency kit has a heavy blanket and a portable power bank, especially before Monday's sub-zero wind chills arrive. If you're planning outdoor activities for the weekend, aim for Saturday morning before the wind speeds ramp up to 16 mph.
