If you’ve been staring at the Jackson Hole Wyoming 10 days forecast trying to figure out if you should pack the heavy-duty Gore-Tex or just a standard puffer, you aren't alone. Everyone does it. Honestly, it’s kinda the local pastime around here—obsessing over whether a "20% chance of snow" means a dusting or a hidden powder day.
Right now, as of Sunday, January 18, 2026, things are looking... well, surprisingly calm. But in the Tetons, calm is usually just the setup for the next big play.
The Current Vibe: Sunny but Chilly
Today is basically a "bluebird" dream. We're looking at a high of 27°F and a current temperature sitting right around 8°F. It’s sunny, the wind is barely a whisper from the north at 2 mph, and the humidity is hanging heavy at 85%. That high humidity usually means the snow on the ground stays crisp rather than turning into that weird afternoon slush you see in lower-altitude resorts.
If you’re heading out tomorrow, Monday, January 19, expect more of the same. Highs will dip slightly to 23°F with a low of 4°F. It’s going to be sunny, so keep that sunscreen handy because the alpine glow at 9,000 feet will absolutely fry your nose if you aren't careful.
Jackson Hole Wyoming 10 Days: The Shift is Coming
Basically, the next few days are your "groomer" days. Tuesday and Wednesday stay fairly stable with highs in the mid-20s. But look closely at Friday, January 23. That's when the "Teton Trickle" starts to wake up.
We’re seeing the night-time precipitation jump to a 40% chance of snow showers on Friday. By Saturday, January 24, we’re looking at light snow during the day and more showers at night, with a high of 21°F. It’s not a massive "dump" yet, but for anyone who knows this mountain, these are the days when the crowds stay inside and the skiing gets quietly epic.
Why the "Teton Trickle" Matters
Most tourists wait for the double-digit snow alerts. They see "2 inches" and stay at the Mangy Moose for another round of spicy margs. Big mistake.

Local legend and meteorologist Jim Woodmencey has often pointed out that our specific mountain geography creates these "micro-events." Even when the valley looks clear, the summit at Jackson Hole Mountain Resort can be getting hammered.
As of mid-January 2026, the summit is already sitting on a 217-inch season total. That’s 103% of the average snowpack. When people talk about "Hero Snow," this is what they mean—a consistent, slow accumulation that fills in the technical lines like Corbet’s Couloir without the high-wind crust you get during major blizzards.
Breaking Down the Forecast (Prose Style)
- Today & Tomorrow: Sunny and clear. Highs of 27°F today and 23°F tomorrow. Lows are staying in the single digits (5°F and 4°F).
- Mid-Week (Jan 20-22): Mostly cloudy to cloudy. Highs stay steady at 24°F or 25°F. Night-time lows hover around 3°F to 5°F.
- The Weekend Pivot: Friday starts clear but turns to snow showers at night. Saturday is your best bet for fresh tracks with a 40% chance of light snow and a high of 21°F.
- Early Next Week (Jan 25-27): Snow showers continue through Sunday and Tuesday. Temperatures actually start to climb a bit, hitting 29°F by the following Tuesday.
What Most People Get Wrong
One thing you’ve probably noticed if you’ve been here before is the "inversion." It’s a weird phenomenon where it’s actually warmer at the top of the tram than it is in the town of Jackson.
You’ll be shivering at 5°F in the parking lot, but once you hit the summit, it might be 20°F and sunny. Always check the summit cams before you decide to bail on a cold morning.
Also, don't trust the "percent chance" of snow too literally. In the Tetons, a 20% chance can easily turn into 6 inches of fresh powder if the wind hits the canyon just right. It’s sort of an atmospheric sneak attack.
Actionable Tips for the Next 10 Days
If you are currently in town or arriving this week, here is the game plan.
Layer like a professional. Since we’re seeing lows of 3°F but sunny days, you need a moisture-wicking base layer. Avoid cotton like the plague; it’ll freeze the second you stop moving.
Watch the Saturday window. With a 40% chance of snow and a drop in temperature to 21°F, Saturday, January 24 is looking like the sweet spot for snow quality. The humidity will be high (95%), so expect that "sticky" snow that grips the terrain well.
Drive for the conditions. If you’re heading over Teton Pass, remember that even a "light snow" forecast can make the road treacherous. Wyoming road reports are your best friend.
Get the waffles. If the wind stays low (around 2-7 mph as predicted), it’s a perfect week for a trip to Corbet’s Cabin. You won't get blown off the ridge, and the clear skies will give you a view all the way to Idaho.
Stay safe, watch the north wind, and enjoy the sun while it lasts—the snow is coming back for the weekend.
