Honestly, if you've lived in the Wabash Valley for more than a week, you know the drill. You wake up thinking it’s a "light jacket" day and by noon you’re questioning every life choice that led you to leave your parka at home. Predicting the 10 day forecast Lafayette Indiana is kinda like trying to guess which way a Purdue basketball game will go in the final thirty seconds—stressful, unpredictable, and usually involves a lot of shouting at the television.
Right now, we are staring down the barrel of a classic Indiana January stretch. As of Thursday, January 15, 2026, the current situation is... well, it's 17°F. But thanks to that 14 mph wind whipping off the Northwest, it feels more like a brisk 3°F. If you’re heading out tonight, expect "partly cloudy" to be the polite way of saying it's dark and freezing.
The Cold Reality of the Next 10 Days
Don't let the "sunny" icons fool you. Friday, January 16, starts off cloudy with a high of 37°F, which sounds almost tropical compared to tonight. But then the light snow starts after dark. It’s that annoying kind of snow—just enough to make the roads slick but not enough to justify a "snow day."
Saturday and Sunday (the 17th and 18th) are going to be those bright, blue-sky days that are secretly miserable. We're looking at highs in the low 20s. Sunday night, the mercury drops to 10°F. If you have pipes that like to freeze, this is your warning.

Monday, January 19, is the real kicker. It’s going to be sunny, but the high is only 11°F. Combined with 20 mph winds? Basically, stay inside. Your face will thank you.
Why Lafayette Weather is a Different Beast
Most people think "it's just the Midwest," but Lafayette has its own quirks. We get these weird micro-climates because of the river and the way the winds pull across the flatlands to the north.
Meteorologists at places like WLFI Weather Team 18 often talk about the "clipper systems" that drop down from Canada. We’re seeing one of those right now. These systems aren't always massive blizzards, but they bring that "bone-chilling" air that makes 20 degrees feel like 0.

Survival Tips for the 10 Day Forecast Lafayette Indiana
First off, layers aren't just a suggestion; they are a religion. If you’re heading to Purdue’s campus or just walking across the John T. Myers Pedestrian Bridge, the wind tunnel effect is real.
If the weather gets too gnarly for outdoor sledding at Murdock Park or skating at Riverside, look for the indoor escapes. The Haan Museum is great if you want to feel cultured while staying warm. Or, honestly, just find a local coffee shop on the "Daily Grind" trail and wait for the sun to come back.
Real Talk on Accuracy
Weather models change. A shift in the wind direction by five degrees can mean the difference between a dusting and three inches of snow. While the 10 day forecast Lafayette Indiana looks fairly dry for the first half, that transition on the 23rd could easily turn into an ice event if the temperatures hover near freezing.

Keep an eye on the barometer. Currently, it's around 29.96 in, which is pretty steady, but when that starts dropping, you know the moisture is coming.
Next Steps for You:
- Check your tire pressure; these 10-degree drops will trigger every sensor in town.
- Stock up on salt before the Friday/Saturday transition.
- Plan your heavy outdoor chores for next Thursday (the 22nd)—it’s your only window of "warmth."
