You think you know Tennessee weather, right? Honestly, Sevierville is a bit of a rebel. One minute you're staring at the Great Smoky Mountains through a crystal-clear lens, and the next, a literal wall of mist swallows the Parkway. It’s kinda legendary for catching tourists off guard.
Basically, if you're looking at a weather forecast Sevierville TN right now, you're seeing a snapshot of a very complex puzzle. Today, January 15, 2026, the current temperature is a crisp 23°F. It feels like 18°F out there because of a light 3 mph wind from the west.
The Immediate Outlook: Shifting Gears
Tonight is clear, but don't get too comfortable with the dry air.
Tomorrow, Friday, January 16, things take a wild turn. We’re looking at a high of 50°F during a cloudy day, but the night brings a 75% chance of rain with a low of 18°F. That's a massive swing. If you're staying in a cabin, make sure the pipes are dripped and you've got the fireplace ready.
Saturday stays interesting. Expect a high of 46°F and a low of 25°F. There’s a 20% chance of rain during the day and a 15% chance of snow at night. It’s that classic Sevierville "maybe-it-will, maybe-it-won't" winter dance.
Why the Forecast Is Never Just One Number
The thing about Sevierville is the elevation. You might be sitting at the Apple Barn in the valley where it’s just chilly, but up at Newfound Gap, it’s a total whiteout.
Most people check the 10-day and assume the whole region is the same. Huge mistake. The mountains act like a giant sponge, trapping moisture from the Gulf. This creates microclimates that can change every five miles.
Looking ahead at the next few days:
- Sunday (Jan 18): Mostly sunny, high 36°F, low 23°F.
- Monday (Jan 19): Sunny, high 37°F, low 16°F.
- Tuesday (Jan 20): Sunny, high 35°F, low 16°F.
The early part of next week looks stable and dry, which is perfect for hitting the shops or taking a scenic drive without worrying about black ice.

Weather Forecast Sevierville TN: Surviving the Extremes
January is statistically the coldest month here. While the average low is usually around 32°F, we’re seeing lows hit 16°F next week. That’s cold even for the locals.
Honestly, the humidity is the silent killer. Even when it’s 30°F, the 54% humidity we have right now makes the air feel heavy and damp. It bites through denim.
What to Pack Right Now
Forget the heavy parka unless you’re standing still. You need layers.
- A moisture-wicking base layer.
- A solid fleece or wool middle.
- A windproof shell.
If you’re heading out on Wednesday, January 21, the high jumps back to 49°F with a 25% chance of snow at night. That kind of flip-flop is why people end up getting sick on vacation. Stay hydrated and don't trust the sun; it's deceptive in the Smokies.

The Long-Range Reality
By the end of next week, the pattern shifts again. Thursday (Jan 22) shows a mix of rain and snow with a high of 44°F. Friday and Saturday (Jan 23-24) bring much warmer air, hitting 53°F and 52°F, but it comes with a 45% chance of rain.
It’s going to be soggy.
If you're planning outdoor activities like ziplining or hiking, aim for the Monday-Tuesday window when the UV index is 3 and the sky is clear. Just be ready for those 16-degree mornings.
When you're tracking the weather forecast Sevierville TN, keep an eye on the wind direction. Northwest winds, like the 11 mph ones we saw today, usually bring in that biting dry cold. When it shifts to the southwest, like it will tomorrow, expect the moisture to follow.
Actionable Advice for Your Trip:
Download a hyper-local app like eastTNweather. National apps often miss the mountain-wave winds and the sudden valley fog that Mike Witcher and other local experts track. Also, always check the National Park Service's "Roads and Weather" Twitter feed before trying to cross the mountain to North Carolina; ice closes those roads way faster than you’d think.
