Honestly, if you've lived in Northeast Indiana for more than a week, you know the drill. You wake up, check the weather forecast Fort Wayne has in store, and then promptly prepare for three different seasons to happen before lunch.
Right now, we are staring down the barrel of a classic January deep freeze. As of Thursday afternoon, January 15, 2026, the temperature is sitting at a crisp 23°F. But that’s the "official" number. If you actually step outside near Jefferson Pointe or head toward the Coliseum, that 12 mph west wind makes it feel more like 12°F.
It’s that biting, "Great Gray Funk" kind of day.
The Clipper and the Cold Front
Basically, a clipper storm is dropping down from Canada. These things are notorious for moving fast and leaving a mess behind. For today, expect it to stay mostly cloudy with a high of 25°F. We’ve got a slight 20% chance of snow during the day, but that bumps up to 25% tonight.
The real shift happens tomorrow.
Friday is looking a bit messier with light snow expected and a high of 33°F. It sounds warmer, but the wind is going to kick up to 17 mph from the southwest. That means your morning commute on I-69 or US-30 is probably going to be slippery. We're looking at a 45% chance of snow tomorrow night.

The Upcoming Deep Freeze (A Survival Guide)
If you think this is cold, just wait. The forecast for early next week is looking legitimately brutal. By Monday, January 19, 2026, we’re looking at a high of only 8°F and a low that drops to 3°F.
Wait, it gets worse.
With 21 mph winds coming off the plains, those wind chill values are going to dive toward -10°F. This isn't "wear a light jacket" weather; it's "where did I put my heavy thermal socks and why do I live in a place where the air hurts my face" weather.
Why Fort Wayne Weather is Such a Headache
People always blame Lake Michigan. While it’s true that places like South Bend get absolutely hammered by lake-effect bands, Fort Wayne is in a weird spot. We are just far enough inland that the heaviest snow usually peters out before it hits us.
But not always.

The topography around the city occasionally funnels that moisture right into Allen County. Usually, we just get the "flurries" or a light dusting of an inch or two. However, when the wind hits that 850 mb level at just the right speed (usually between 10 and 45 mph from the northwest), we get those surprise snow showers that the national models often miss.
Steve Eddy over at the National Weather Service office in Northern Indiana has pointed out before that these events are most common right after a major storm passes through. It's the "backdoor" snow that catches people off guard.
Looking at the Numbers (No Boring Tables Here)
If you're trying to plan your month, here’s the gist of what January usually looks like in the 46808. Historically, our average high is around 32°F, with lows dipping to 20°F. We usually see about nine days of measurable precipitation.
This year? We're trending a bit colder than those 12-year averages.
- Saturday, Jan 17: High of 22°F, mostly cloudy, 20% snow chance.
- Sunday, Jan 18: High of 20°F, dropping to a low of 8°F at night.
- Monday, Jan 19: High of 8°F. Yes, single digits for the high. Clear but frigid.
- Tuesday, Jan 20: Bouncing back to 27°F, but the low stays at 2°F.
What Most People Get Wrong
The biggest misconception about the weather forecast Fort Wayne provides is that "partly sunny" means it'll be a nice day. In January, "partly sunny" is often a trap. The sun might come out, but in this part of the country, clear skies in the winter usually mean the heat is escaping the atmosphere.

Clear nights are almost always the coldest.
If you see a forecast for a clear Monday night, like we have coming up with that 3°F low, you’d better make sure your pipes are protected and your pets are inside.
Real Actionable Steps for the Next 48 Hours
Don't just read the forecast; actually do something about it.
- Check your tires now. That Friday morning light snow is exactly the kind of "greasy" snow that causes slide-offs on the 469 loop.
- Layers are your best friend. Since the "feels like" temperature is going to fluctuate between 12°F today and -10°F by Monday, you need moisture-wicking base layers.
- Fuel up. Never let your gas tank get below half when a clipper is moving through. If you get stuck in a backup on the highway, you'll want that heater running.
- Watch the wind. Saturday and Monday will have gusts over 15-20 mph. If you have loose patio furniture or holiday decorations still out (no judgment), get them secured.
The bottom line is that Fort Wayne weather is a game of patience. We're heading into the coldest stretch of the month. Stay updated with the NWS Northern Indiana office and keep a shovel in the trunk. You're going to need it by Friday morning.
