A cold front will broom some rain across Middle Tennessee tonight and overnight. The HRRR model illustrates:
This will help wash some of this snow away.
When the rain ends, a cold northwest wind will blow our wee hour temps down from 46° into the mid-40°s, where they’ll be stuck until dark, when we start to move toward freezing.

Remaining Snow/Ice will refreeze tonight. The overnight low is 30°. Secondary roads are especially vulnerable because they are often shaded and less trafficked.
We don’t know the road conditions, we can only tell you how we think the weather might be impacting them. Consult traffic sources on Twitter (such as @TrafficJamSam) and the TDOT Smartway map/cameras.

When the weather balloon went up just after 5 AM, it was 14°; however, there was a large “inversion,” a fancy weather word that means it’s warmer overhead than it is down here on the ground. Temps from 5,000 feet all the way up to 10,000 feet were above freezing. Why am I boring you with that? Because it’s a good sign we’re going to warm up today. Sunshine is on the way. High 37°. Some ice and snow will melt.

At 7:17 AM, if you were on the NW side of this line, you were on your way winning the snow lottery. Snow was accumulating as an impressive convective snow band raced north up 65.

Major travel impacts expected.
Temps will fall into the 20°s after noon. Stuff will freeze and hang around for the rest of the day, tonight, overnight, and with temps not forecast to get above freezing Saturday, much of Saturday too.
Current Radar
Temps have hovered at and just above freezing this afternoon. After dark, we should be at or below freezing. Beware of black ice, especially on bridges and overpasses.
By midnight, we should be at 30°, where we will hold for most of the morning before dropping to 28° just before sunrise.
