So, you’re looking at the 15 day weather Nashville TN forecast and wondering if you should pack a parka or a light windbreaker. Honestly, that’s the classic Nashville struggle. This week, we’re seeing a total rollercoaster that perfectly illustrates why locals say if you don't like the weather here, just wait five minutes. It’s mid-January 2026, and we’ve already swung from a balmy 65°F yesterday down to a messy mix of rain and snow today.
Nashville's winter isn't usually a frozen tundra, but it isn't exactly a tropical escape either. It’s just... weird.
The Immediate Outlook: Shivers and Sunny Breaks
If you're looking at the immediate window from Wednesday, January 14, through the next week, brace yourself. Today is the messy part. We've got a 58% chance of precipitation that’s currently flip-flopping between rain and snow. It’s that wet, heavy slush that makes the I-65 a nightmare. Don't expect much accumulation, maybe a dusting on the grass if we're lucky, but the real story is the temperature drop. We’re heading for a low of 22°F tonight.
Tomorrow, Thursday the 15th, is going to be crisp.
The sun will be out, which is a total lie because the high is only hitting 35°F. It’s one of those "sunny but freezing" days where you'll want your heaviest coat for that walk down Broadway. By Friday, we get a little rebound back into the 50s before the weekend settles into the high 30s.

Mid-Range Volatility
As we push into next week, Monday, January 19, and Tuesday, the 20th, look mostly sunny but cold. We’re talking highs in the upper 30s and lows dipping into the low 20s.
Then comes the "warm" surge.
By Wednesday the 21st and Thursday the 22nd, temperatures climb back into the 40s and low 50s. This is typical Nashville. We get these three-day stretches where you think spring is arriving early, followed immediately by a rain-to-snow transition that shuts down the schools because of a half-inch of slush.
What the Models Are Actually Telling Us
Meteorologists at the National Weather Service (NWS) Nashville office have been tracking a fairly standard La Niña-to-Neutral transition this winter. According to long-range outlooks from the Climate Prediction Center, we are seeing slightly below-normal precipitation for the rest of the month, but the temperatures are staying stubbornly average or just below.

Historically, January is the coldest month in Music City.
We average about 22 days where the temp drops below freezing. If you're planning a trip or just trying to survive your commute, keep these patterns in mind:
- The "Rain-Snow" Line: Nashville sits right on a geographical transition zone. A tiny shift in the jet stream determines if we get a cold rain or a "snow-pocalypse."
- Wind Chill Factors: With average wind speeds around 10-15 mph this week, that 38°F high is going to feel like 28°F.
- The Humidity Factor: Even in winter, Nashville is humid (around 64% today). That "wet cold" gets into your bones way differently than a dry mountain cold.
Surprising Facts About Nashville Winters
Most people think the South doesn't get snow. While we don't get Buffalo-level drifts, Nashville averages about 4.7 inches of snow per year. Most of that happens in January and February. Interestingly, the record high for January was a whopping 78°F back in 1952, while the record low was -17°F in 1985. We haven't seen those extremes this year, but the potential for a 40-degree swing in 24 hours is always there.
Basically, your car needs an ice scraper and an umbrella at all times.

Why the 15-Day Forecast Changes So Often
You've probably noticed the 15 day weather Nashville TN forecast on your phone looks different every time you open it. That’s because the Cumberland Plateau to our east and the Tennessee River Valley to our west create a weird little pocket. Storm systems coming up from the Gulf of Mexico hit the cold air coming down from Canada right over Middle Tennessee. It’s a literal battleground for air masses.
Practical Advice for the Next Two Weeks
Don't trust a single layer of clothing. If you're heading out for a night at the Ryman or a Preds game, do the "Tennessee Layering." A moisture-wicking base, a sweater, and a windproof outer shell.
- Check the Lows: The daytime high is for the tourists; the overnight low is for the locals. That 22°F low tonight means black ice on bridges tomorrow morning.
- Watch the Wednesday/Thursday Turn: Mid-week shifts are common here.
- Protect the Pipes: If you're in an older house in East Nashville or Germantown, those lows in the 20s mean it's time to drip your faucets.
- Humidity Management: Your skin is going to hate the flip-flop from humid rain to dry heater air. Stock up on the heavy-duty lotion.
The back half of this 15-day window—around January 23 to 28—shows hints of more light rain and highs settling in the low 50s. It’s not "pool weather" by any stretch, but it’s manageable. Just keep an eye on those overnight dips, as they are the real killers for morning traffic.
Stay weather-aware, especially during the rain-to-snow transitions today and next Monday. Those are the windows where Middle Tennessee roads get the most unpredictable. Your best bet is to keep a "winter kit" in your trunk—blanket, extra gloves, and maybe some snacks—just in case a dusting of snow turns the morning commute into a four-hour parking lot.
To prepare for the freeze, check your outdoor spigots today and ensure any sensitive plants are covered before the 22°F dip tonight.
