If you’ve lived in the Tennessee River Valley for more than a week, you know the drill. One day you’re wearing a T-shirt at Coolidge Park, and the next, you’re digging through the garage for that one ice scraper you haven’t seen since 2024. Honestly, looking at the chattanooga 14 day forecast right now is like watching a weather app have a minor identity crisis.
We are currently sitting in that weird mid-January pocket where the "Scenic City" can't decide if it wants to be a winter wonderland or just a very damp, chilly version of itself.
Right now, as of January 17, it’s actually a decent 42°F outside. Mostly sunny. Pretty standard. But if you’re planning your life for the next two weeks, don’t let that modest sunshine fool you. Things are about to get a bit "Chattanooga-style" complicated.
The Immediate Outlook: Sun, Shivers, and the Occasional Flurry
Basically, the next few days are going to be a rollercoaster of "crisp" and "wait, why is it 20 degrees?"
Today, Saturday, we’re looking at a high of 51°F. That’s the peak. After this, the floor kinda drops out. By tomorrow, Sunday the 18th, that high struggles to hit 39°F. If you’re heading to the Market or walking the Walnut Street Bridge, you’ll definitely feel that 9 mph northwest wind cutting through your layers.

What to expect early next week:
- Monday (Jan 19): High of 43°F, but the real story is the overnight low of 20°F.
- Tuesday (Jan 20): Even colder. We’re looking at a low of 19°F.
- Precipitation: There's a tiny 5-10% chance of snow flurries floating around Monday and Tuesday. It’s probably not enough to shut down the ridge, but in this town, two flakes on a windshield usually results in a run on the milk and bread aisles at Publix.
The Mid-Range Shift: When the Rain (and Snow?) Returns
Around Wednesday, January 21, the pattern shifts. We jump back up to a high of 52°F, but it comes with clouds. Then things get messy.
The chattanooga 14 day forecast shows a significant increase in moisture toward the end of next week and into the following weekend. Saturday, January 24, starts the trend with a high of 58°F—the warmest day in the outlook—but it’s a "wet warm." We've got light rain moving in overnight.
By Sunday the 25th, the chance of rain hits 70%. If you were planning on hiking Sunset Rock, maybe pivot to an indoor climb at High Point or a trip to the Tennessee Aquarium.
Monday, January 26, is the one to watch. The forecast is currently calling for "rain and snow" with a 75% chance of precipitation. With a low of 25°F that night, things could get interesting on the bridges and overpasses.

Decoding the Chattanooga Winter Vibe
Why does it do this? Geography, mostly. We’re tucked into a valley, so we get these cold air damming events where the chilly air just sits here like an uninvited house guest.
According to historical data from the National Weather Service, January is statistically our coldest month. Average highs usually hover around 48°F with lows near 30°F. The current forecast is actually trending a bit colder than those "normals" for the overnight stretches, which means your heating bill is likely going to take a hit.
Packing and Prep Reality Check
If you're visiting or just trying to survive your commute, you need a strategy. Forget the heavy Arctic parka unless you’re standing still for three hours.
Layers are your best friend.

- Base: Moisture-wicking stuff if you're hiking Signal Mountain.
- Mid: A fleece or a heavy flannel.
- Shell: Something waterproof.
Honestly, the humidity here makes 40°F feel like 30°F. It’s a "wet cold" that gets into your bones. Don't forget your polarized sunglasses, though. When the sun hits the frost on the trees atop Lookout Mountain, the glare is actually blinding.
Making the Most of the 14-Day Window
Despite the shivering lows, this is actually a great time to be in town if you hate crowds. The Asian Lantern Festival at the Zoo is still wrapping up (check the dates, it usually runs through mid-January), and "Ice on the Landing" at the First Horizon Pavilion is the quintessential winter move.
If the rain on the 25th and 26th ruins your outdoor plans, ducks into the Hunter Museum or grab a coffee in the Bluff View Art District. The views of the river are actually better in winter because the leaves are gone, revealing the limestone bluffs and the architecture of the bridges in a way you can't see in July.
Actionable Next Steps:
- Check your pipes: With those 19°F and 20°F lows on Tuesday and Wednesday, make sure your outdoor hoses are disconnected.
- Plan for Monday the 26th: If you have a commute over the ridges (Signal, Lookout, or Missionary Ridge), keep a very close eye on that "rain and snow" mix. Even a little bit of slush makes those curves treacherous.
- Layer up for the weekend: If you're heading out this Saturday or Sunday, remember that 12 mph wind on Saturday will make that 51°F feel a lot more like 40°F.
Stay warm, keep an eye on the radar, and maybe keep a bag of salt by the driveway just in case that Monday "mix" decides to stick around.
