Honestly, if you're checking the Lenoir City Tennessee temperature right now, you’re probably either planning a lake day or wondering if you need to wrap your pipes. It’s a weirdly specific thing to track. But here in East Tennessee, the weather has a personality. It’s not just about a number on a screen; it’s about that damp chill that settles into your bones or the humid heat that feels like a wet wool blanket.
Right now, as of early Saturday morning, January 17, 2026, it is 42°F in Lenoir City.
That doesn't sound too bad on paper. But with a southwest wind at 7 mph, it actually feels like 37°F. There’s a light rain falling, and the humidity is sitting heavy at 78%. Basically, it's that classic "Loudon County damp" where the air feels heavier than the thermometer suggests.
The Current Mood of Lenoir City Weather
The forecast for the rest of today, Saturday, January 17, shows we’ll hit a high of 46°F. Not exactly t-shirt weather. By tonight, the temperature is expected to drop significantly to a low of 26°F.

If you’re out and about, keep an eye on the sky. While it’ll be partly sunny for most of the daylight hours, there’s a 10% chance of rain. The real shift happens tonight when that 5% chance of snow creeps in. It’s not much, but in this part of the state, even the mention of a snowflake can send people rushing to the Food City for bread and milk.
The wind is going to pick up a bit too. We’re looking at around 11 mph coming from the southwest. It’s the kind of day where you think you're fine in a light jacket until you turn a corner near the Tennessee River and that breeze hits you.
Why the Temperature in Lenoir City Tennessee Is So Unpredictable
People who don't live here think the South is always warm. They're wrong. Lenoir City sits in a unique spot—tucked between the Great Smoky Mountains to the east and the Cumberland Plateau to the west. This geography creates a "valley effect" that traps air.
During the summer, this means the humidity sticks to you like glue. In the winter, like we're seeing today, it means cold air can pool in the low-lying areas near Tellico Lake and Fort Loudoun Lake.
January Expectations vs. Reality
Usually, January is the coldest month for us. The average high is typically around 48°F, which makes today's 46°F pretty much on par with historical norms. The record low for January in this area is a bone-chilling -14°F (set way back in 1985), so 26°F tonight is cold, but it’s nowhere near "pipes bursting everywhere" territory.

- Average January High: 48°F
- Average January Low: 28°F to 32°F
- Typical Humidity: 70%
Most people get caught off guard by the "feels like" factor. Because we are so close to major water bodies, the dew point and humidity play a massive role in how the Lenoir City Tennessee temperature actually impacts your day. A dry 40°F in Colorado feels like a spring day. A damp 40°F in Lenoir City feels like an ice bath.
Planning Your Week Around the Forecast
Looking ahead at the next few days, we’re seeing a bit of a rollercoaster. Sunday, January 18, is looking even colder with a high of only 31°F. If you have outdoor plans, you might want to move them to later in the week. By Friday, January 23, we’re expecting things to bounce back up to around 51°F.
That’s the thing about East Tennessee. If you don’t like the weather, just wait fifteen minutes. Or a couple of days.
What This Means for You Locally
If you’re a local or just visiting the WindRiver community or hanging out at the marina, here is the reality:
- Morning commuters: Watch for "black ice" on the bridges, especially over the river, when the temp hits that 26°F low tonight.
- Pet owners: Bring them in. 26°F is too cold for most outdoor animals.
- Gardeners: If you’ve got any early-blooming plants (sometimes our winters are weirdly mild and things start popping up), cover them tonight.
Honestly, the Lenoir City Tennessee temperature is just one part of the story. The real trick is dressing in layers. You’ll start the day in a heavy coat and might find yourself down to a flannel by 2:00 PM if the sun breaks through those clouds.
Stay warm out there, and maybe keep an extra blanket in the car just in case that 5% chance of snow turns into something more interesting.
Actionable Next Steps
- Check your tire pressure: Cold snaps like the one coming tonight (dropping to 26°F) often trigger those annoying "low pressure" sensors.
- Prepare for Sunday: Since tomorrow's high is only 31°F, today is the day to run your errands while it’s still in the mid-40s.
- Winterize outdoor faucets: If you haven't yet, get those covers on before the overnight freeze hits.
