Hold Onto Your Hats!
In addition to strapping down any loose items outside, you’ll need the rain gear tonight/tomorrow. Latest high resolution guidance shows rain moving through the Davidson/Williamson County area:
Windy Times Continue, Rain Off and On This Week
Clouds Increasing Tonight, Wet Week Ahead
Sunny Now, Increase in Cloud Cover Through the Evening Hours
We officially hit that above freezing mark this morning at 9 AM. At least for next 7 days, we do not expect to go below the freezing mark. Say goodbye to those freezing temperatures!
For the rest of the day today, we will begin to notice our skies becoming gradually cloudier.
One Last Night Below Freezing; Windy, Wet, Rainy Week Ahead
One More Night Below Freezing
We never officially got above freezing at BNA (high 30°), but remember, the official temp is measured inside a shade box. Sunlit areas very likely rose above freezing, aiding in snow/ice melt.
Ice you can see, and black ice you can’t see, should still be an issue on many secondary roads tonight and in the morning. We will drop to 20° before the sun comes up Monday morning.
Warm & Wet Week Ahead
Warming Up: 29° Today, Still Below Freezing
Officially, BNA dropped to 8° this morning. A few personal/COOP weather stations around town went lower, 2° in Brentwood and 3° in Franklin.
Today’s official high is 29°, but that’s in the shade; most places exposed to the sun should go over freezing and evaporate/melt the snow. Shaded areas will have a more difficult time clearing ice/snow.
Extreme Cold Tonight, Warm Up On The Way
Cold Temps Over the Next 24 Hours, Clear Skies Dominate
Extremely Cold Temperatures Tonight, & Early Tomorrow Morning
While the snow has passed us, do not expect for temps to go above freezing until Monday. This weekend will be extremely cold, even with the sun shining.
Winter Weather Advisory Cancelled; Very Cold Overnight/Weekend

Snow Q & A
There are Two Chances for Snow over the next 24 hours.
Chance #1: Thursday, From Now Until 9 PM
Should You Panic? No.
Why Not? Most of it looks like it will go north of us.
Our current radar also shows the majority of it skating across the southern Kentucky border which is what the HRRR model below thought it would do.
Two Rounds of Snow Chances, One Today, One Friday
Current Radar
There are two chances for very light snow accumulations today and tomorrow. One-quarter to one-half inch of snow total, with only minor travel problems.
Round 1 — Today: Winter Weather Advisory Begins at Noon, Chance of Snow the Rest of the Day
First things first, our Winter Weather Advisory that covers both Davidson Counties and Williams Counties goes into effect today at noon and will last through midnight tonight.
Here is the text of the advisory:
New Model Data Has Arrived To Add More Confusion & Uncertainty
Tonight – Super Chill Forecast
Clouds are increasing. Tonight is just another cold night. The Winter Weather Advisory is not for tonight.
Winter Weather Advisory from Thursday at Noon Until Thursday at Midnight
Current expectations: under 1″ of snow
Mixed model signals betray any meaningful confidence in the forecast
Here’s the text of the Winter Weather Advisory:
This advisory DOES NOT MEAN we will get a lot of snowfall. We are currently expecting up to one inch but will likely see less than that. A dusting appears more likely.
