Honestly, if you’re looking at the weather Newport TN hourly forecast right now, you’re probably seeing a lot of "clear" and "sunny" icons. It looks peaceful. But anyone who’s spent a winter in the foothills of the Great Smoky Mountains knows that the numbers on your screen only tell half the story.
It’s Sunday night, January 18, 2026. Right now, it’s a crisp 26°F outside. If you step onto your porch, it actually feels more like 20°F because of a light 5 mph breeze coming off the southwest. Humidity is sitting at 65%, which is high enough to make that cold air feel like it’s biting right through your flannel. This is classic Cocke County winter: clear skies, no snow in the immediate cards, but a deep, bone-dry chill that settles into the Pigeon River valley and stays there.
The Hourly Reality For Newport Tonight
You've probably noticed that Newport doesn't play by the same rules as Knoxville or even Sevierville. Because we’re tucked into that geographic pocket where the mountains start to rise, our hourly shifts can be dramatic.
Tonight, the temperature is going to bottom out at 25°F. It’s going to stay clear, meaning we don’t have a cloud blanket to trap any of the day’s warmth. By tomorrow morning, you’re looking at a slow climb.

- 10:00 PM: 26°F (Feels like 20°F)
- Midnight: Hovering around 25°F
- 6:00 AM: The coldest point, likely dipping to that 25°F low.
If you’re heading out early Monday morning, don't let the "sunny" forecast for tomorrow fool you. The high for Monday is only expected to hit 34°F or 39°F depending on which pocket of the county you're in. That’s barely above freezing.
Why January 18 Is A Turning Point
Historically, mid-January is when Newport enters its true "cold season." According to data from the National Weather Service and long-term climate studies of the region, the lowest daily average high for the year usually hits right around January 13th-14th, at about 48°F. We are currently well below that average.
The "Arctic Revenge" headlines you might be seeing aren't just clickbait. While we aren't seeing the massive snow totals that the Great Lakes are currently getting, the secondary impact—the plunging temperatures—is very real for East Tennessee.

The Mountain Effect: Why Your App Might Be Lying
Most weather apps pull data from the Morristown Moore-Murrell Airport (KMOR). While that’s close, Newport’s elevation of roughly 1,098 feet and its proximity to the Cherokee National Forest create microclimates.
Basically, it can be 35°F in town but 28°F if you live up toward Halls Top or Albright Grove. In January, the cloud cover in Newport is at its annual peak, overcast about 56% of the time. This keeps the sun from warming the ground, which is why that "feels like" temperature rarely matches the actual thermometer reading during the day.
Wind and Humidity Factors
Southwest winds at 8 mph might sound like a gentle breeze, but in 30-degree weather, it’s a heat-thief. The humidity today is 63% to 65%. In the summer, that’s "muggy." In the winter, that moisture in the air conducts heat away from your body faster. It’s why a 26°F night in Newport feels significantly colder than a 26°F night in a high-desert climate like Denver.

Surviving The Next 24 Hours
If you're looking at the weather Newport TN hourly to plan your Monday, here’s the no-nonsense breakdown:
- Morning Commute: Expect frost. Even with a 0% chance of precipitation tonight, the humidity is high enough that "black ice" on bridges over the Pigeon River is a possibility.
- Outdoor Work: UV index is 0. You won't get any warmth from the sun’s rays, even if it looks bright out. If you're working outside, you need wind-resistant layers.
- Home Maintenance: It’s been cold enough long enough that pipes in older homes or crawlspaces might start feeling the stress. If you haven't dripped your faucets, tonight's 25°F low is the time to start.
Looking Ahead: Is Snow Coming?
While tonight is clear, the long-term trends for late January in Newport often show a "frozen mix." We average about 3.4 inches of snow in January, and there's a 10% chance of a stray flake today that didn't quite materialize. Keep an eye on the weekend of January 24th; early models suggest a 40% to 50% chance of a frozen mix as a new system moves through the Appalachians.
For now, stay warm, keep the woodstove stoked if you've got one, and remember that in Newport, the "feels like" temperature is the only one that actually matters when you're out in the elements.
Actionable Steps for Newport Residents:
- Check your tire pressure tonight; these 20-degree drops cause PSI to plummet.
- Bring in any remaining outdoor pets or sensitive plants before the midnight dip.
- Layer up for tomorrow's commute—the 34°F high won't feel warm until late afternoon.
