Honestly, if you're looking at the Wasilla weather 10 day forecast right now, you’re probably seeing a lot of grey icons and numbers that don't quite tell the whole story. January in the Mat-Su Valley is weird. One minute you're scraping a thin glaze of ice off your windshield, and the next, you’re watching a light, powdery snow drift across the Parks Highway like ghosts.
It’s currently 26°F out there as of mid-morning, Saturday, January 17, 2026. The air is pretty still—just a 1 mph breath from the north—but it feels heavy. Humidity is sitting at 68%, and the sky is a solid lid of clouds. If you’ve got errands to run at Target or need to hit the Brew House, now is the time before the afternoon shift starts.
The 10-Day Outlook: A Slow Slide into the Freezer
People usually think Alaska in January is just one long, frozen nightmare, but this week is actually starting out kind of mild for us. We're hovering right around the freezing mark today with a high of 32°F.
Don't let that "warmth" fool you.
The forecast shows a 46% chance of snow this afternoon, and tonight things get messy. We’re looking at a 10% chance of rain. Rain in Wasilla. In January. That’s the recipe for the "Mat-Su Ice Skating Rink" on every side street from Lucille to Seldon.

Here is the basic breakdown of what the next several days look like:
- Sunday (Jan 18): Expect a high of 33°F. It’ll stay cloudy during the day, but the clouds might break a bit at night.
- Monday (Jan 19): Mostly cloudy and starting to dip. High of 28°F, low of 23°F.
- Tuesday (Jan 20): Holding steady at 28°F. This is actually predicted to be one of the clearer days of the month, so keep an eye out for a glimpse of the Talkeetnas.
- Wednesday (Jan 21): The slide begins. High of 25°F, low of 15°F.
By next weekend, the "mild" weather is a memory. Saturday, January 24, drops us down to a high of 20°F and a low of 9°F. Monday, January 26, looks even crispier with a high of only 17°F and a low of 7°F.
Why the Valley Winds Change Everything
If you’ve lived here more than a week, you know the forecast is basically a polite suggestion until the wind decides to show up. Right now, the winds are negligible—2 to 3 mph—but by the end of this 10-day stretch, we're expecting 11 mph gusts from the north.
In the Valley, 11 mph can feel like a personal insult when the temp is 17°F.

The humidity is also going to drop. We're starting the week at 72% humidity, which makes the cold feel "wet" and bone-chilling. By the time we hit the 25th, the humidity falls to 57%. It’ll be a "dry" cold, which is easier on the joints but harder on your skin and your knuckles.
Dealing with the "Mat-Su Glaze"
When the high is 32°F or 33°F like it is today and tomorrow, we get that dreaded melt-freeze cycle. The snow from this afternoon (46% chance) might turn into a slushy mess if that 10% rain chance hits tonight. Then, when it drops to 25°F on Monday, that slush becomes a solid sheet of glass.
Basically, if you haven't put your studs on yet, you're playing a dangerous game.
Expert locals know that the Wasilla weather 10 day forecast is as much about road conditions as it is about the temperature. If you’re commuting into Anchorage, give yourself an extra 20 minutes for the stretch near the Eklutna flats. The wind there doesn't care what the Wasilla airport sensors say.

Survival Tips for the Next 10 Days
- Check your tailpipe. With the snow expected today, make sure your exhaust isn't blocked if you're idling your truck to warm it up. Carbon monoxide is a real threat when the snow piles up.
- Layers are non-negotiable. We're moving from 33°F down to 7°F. That’s a 26-degree swing in a week. You’ll want moisture-wicking base layers for the early week and the heavy down parka for the next Monday.
- Watch the "Polar Night" light. We’re only getting about 6.4 hours of daylight right now. Sunrise is around 9:50 AM and sunset is at 4:20 PM. If the clouds break on Sunday night like they're supposed to, keep an eye out for the Aurora—though the UV index is a flat 0, the geomagnetic activity can still surprise you.
It's a typical January stretch. It’s grey, it’s a bit snowy, and it’s about to get a whole lot colder.
Get your wood stacked and your salt buckets ready. The back half of this forecast is going to require a lot more coffee and a lot more indoor time. Stay safe on the roads and keep those headlamps charged.
Actionable Next Steps: Check your vehicle's emergency kit today before the snow hits this afternoon. Ensure you have a shovel, sand or kitty litter for traction, and extra blankets, as the temperatures will drop significantly into the single digits by next week.
