Honestly, if you live in Middle Tennessee, you’ve probably learned to never trust a sunny day in January. One minute we are all wearing light jackets and grabbing coffee on a patio, and the next, everyone is sprinting to Kroger for bread and milk because a dusting of snow is "imminent." It’s kinda the Nashville way.
Right now, we are sitting in that weird winter limbo. But if you're looking at the nashville tn extended forecast, things are about to get significantly more "Tennessee Winter" and a lot less "Mild South."
What the Numbers Actually Look Like
Let’s get into the weeds. Today, Saturday, January 17, 2026, we’re looking at a high of 40°F. Not terrible, but with the wind coming out of the west at 12 mph, it’s going to feel a lot sharper than the thermometer suggests. By tonight, we’re dipping down to a bone-chilling 20°F.
Tomorrow is where the real cold snap settles in. Sunday’s high is only going to hit 33°F. That is basically the freezing mark all day long. If you have plans to be out at Broadway or hitting a park, you’re going to want the heavy-duty parka.

Here is the quick breakdown of the coming week:
- Monday, Jan 19: Sunny but freezing. High of 32°F, low of 20°F.
- Tuesday, Jan 20: A tiny bit of relief. We climb to 38°F. Still clear skies.
- Wednesday, Jan 21: This is the pivot point. It gets "warmer" with a high of 46°F, but the clouds roll in, and we’re looking at a 45% chance of snow overnight.
That Mid-Week Snow Threat
Most people get Nashville snow wrong. They think if it isn't a blizzard, it isn't a problem. But in a city where we have roughly two snowplows for the entire county and a lot of very steep hills, even a "slight" snowfall can turn side roads into literal death traps.
Wednesday night into Thursday morning is the timeframe to watch. We’re expecting moderate snow on Thursday, January 22, with a 70% chance of precipitation. The high will hover around 41°F, which means we might see that messy transition from rain to slush to snow.

Why the Nashville TN Extended Forecast is So Unpredictable
Basically, we’re stuck in a battle between Gulf moisture and Arctic air.
Historical data shows January is usually our coldest month, averaging a high of 45°F and a low of 28°F. We are currently tracking slightly below those averages for the next ten days. According to the Old Farmer’s Almanac and recent NWS briefings, this late-January window is traditionally when the "winter punch" happens.
If you're traveling here, don't just look at the high temperatures. Humidity in Nashville during January usually sits around 85% to 89%. That "wet cold" sinks into your bones in a way that dry cold out West just doesn't.
Long-Range Outlook for Late January
Looking further out toward the end of the month, the trend stays chilly.

- Sunday, Jan 25: We might see a mix of rain and snow with a high of 33°F.
- Monday, Jan 26: It gets even colder. We’re talking a high of only 28°F and a low of 14°F.
That 14°F low on the 26th is no joke. That’s the kind of weather that causes pipes to burst if you haven’t dripped your faucets.
Practical Steps to Handle the Chill
Don't be the person caught off guard when the mercury drops.
- Drip those faucets: When we hit those mid-teens on the 26th, your plumbing is at risk.
- Check your tires: Drastic temperature drops mean your tire pressure is going to scream at you.
- Layering is king: Since we swing from 46°F to 20°F in a matter of 24 hours, you need a base layer, a fleece, and a windbreaker/shell.
- Download a local radar app: National apps often miss the micro-climates of Middle Tennessee.
The nashville tn extended forecast shows a clear pattern: a dry, cold start to the week followed by a messy, wintry mix by Thursday. Keep your gas tank at least half full and maybe grab that extra bag of salt for your driveway now before the crowds hit the stores on Wednesday. Stay warm out there.
Actionable Insight: If you have outdoor pets or sensitive plants, move them or protect them by Sunday night, as the consistent sub-freezing lows starting early next week will be unforgiving.
