Arkansas weather is a moody beast. One minute you’re walking down Dickson Street in a light hoodie, and three hours later, the wind is howling off the Ozark Plateau like it has a personal vendetta against your earlobes. If you’ve lived here for more than a week, you know the drill: keep an ice scraper in the trunk even if the forecast says 60 degrees.
Today is Saturday, January 17, 2026, and honestly, it’s a bit of a reality check. We’re sitting at a crisp 23°F tonight, but with that northwest wind hitting at 13 mph, it actually feels like 11°F. It’s the kind of cold that makes you question why you didn't just stay in bed. The sky is clear for now, and the humidity is sitting at 39%, so at least we aren't dealing with that damp, bone-chilling mist that sometimes crawls up from the hollows.
The Week Ahead: A Wild Ozark Seesaw
If you’re looking at the fayetteville arkansas weather forecast for the next few days, pack your layers. Sunday looks gorgeous but deceptive. We’re hitting a high of 40°F, which sounds almost balmy compared to tonight, but the low is dropping right back down to 13°F.
Monday is where things get interesting. We’re expecting a high of only 25°F with a 10% chance of snow. Now, in some parts of the country, a 10% chance of snow is a joke. In Fayetteville? That’s enough to make people start eyeing the bread and milk aisles at Harps. By mid-week, though, we’re swinging back up toward 50°F on Wednesday. This is classic Northwest Arkansas—a constant tug-of-war between Canadian cold fronts and Gulf moisture.

Understanding the "Ozark Effect"
Why is the weather here so hard to pin down? It’s basically the topography. We aren’t just "in the mountains"; we’re on a plateau. Fayetteville sits at an elevation that catches wind differently than, say, Fort Smith or Little Rock.
When a cold front moves in from the plains, there’s nothing to stop it until it hits us. This is why our "feels like" temperatures are often drastically lower than the actual thermometer reading.
- The Northwest Wind: This is the culprit. When it comes from the northwest, it’s bringing dry, frigid air straight from the Dakotas.
- The Humidity Factor: Even in winter, our humidity stays around 30-40%. It’s just enough to make the air feel "heavy" when it gets cold.
- The Snow Mirage: We don't get massive blizzards often, but we do get "ice events." Because we’re in a transition zone, we often see rain turn to sleet or freezing rain before it ever becomes actual snow.
What Most People Get Wrong About January in NWA
A lot of newcomers think January is just a solid block of grey, miserable cold. That’s not really true. If you look at the historical data from the National Weather Service in Tulsa (which covers our neck of the woods), Fayetteville actually sees a fair amount of sun in the winter.

Tomorrow, January 18, is a perfect example: nothing but sun. But don't let the bright light fool you. The UV index is a 2, and the southwest wind will be gusting up to 16 mph. It’s "bright-cold," the kind of weather where you need sunglasses and a heavy parka at the same time.
Real Talk: Dealing With the Ice
The 2026 season has been relatively tame so far, but long-time residents still talk about the 2009 ice storm like it was a war. In Fayetteville, we don't fear the snow; we fear the ice. Our hills make even a thin glaze of freezing rain a nightmare for driving.
If the forecast mentions "rain and snow" mixed—which is currently on the radar for next Saturday, January 24—that's your cue to stay home. We’re looking at a high of 39°F and a low of 22°F that day. That transition through the freezing point is exactly when the roads get treacherous.

Survival Tips for the Fayetteville Winter
Basically, you need a strategy. Don't just trust the little sun icon on your phone.
- The 10-Degree Rule: Always subtract 10 degrees from the forecast high if you’re going to be in the shade or near the university campus where the wind tunnels are real.
- Water Pipes: When we see lows of 12°F or 13°F like we're seeing tonight and tomorrow, it's time to drip the faucets. Better safe than dealing with a flooded basement.
- The Layering Hierarchy: Base layer for moisture, middle layer for insulation, and a wind-breaking outer shell. If you don't have a windbreaker in Fayetteville, you're doing it wrong.
Looking toward the end of the month, the trend seems to be a slow climb toward more "light rain" and "showers" by Friday, January 23. It’s going to get damp before it gets cold again.
Actionable Steps for the Next 48 Hours:
- Check your tire pressure: These 30-degree temperature swings will make your "low pressure" light pop on faster than you can say "Woo Pig."
- Reverse your ceiling fans: Set them to clockwise at a low speed to push the warm air trapped at the ceiling back down to your living space.
- Stock the "Ice Kit": Make sure you have a bag of salt or sand for your driveway before the Saturday/Sunday mix hits next week.
The fayetteville arkansas weather forecast is a moving target. It requires a bit of patience and a lot of flannel. Stay warm out there, and maybe keep an extra blanket in the car—just in case the Ozarks decide to pull another fast one.
