The National Weather Service in Huntsville posted a *Dense Fog Advisory* until 7 AM Thursday, and the National Weather Service in Nashville posted a *Freezing Fog Advisory* until 9 AM Thursday for much of Middle and East Tennessee.

The biggest challenge for travel in North Alabama through Thursday morning is visibility.

In spots, it had already fallen below a tenth of a mile by 9:30 PM.

Higher elevations have the thickest fog; those some areas have at least a small chance of some patchy bridge ice early Thursday as temperatures hover near 32ºF.

Forecast Lows at 6 AM Thursday (pink line = 32ºF)

Huntsville, Decatur, Athens, Cullman westward through The Shoals: expect fog and wet roads as a few spotty light showers move through the region overnight. Higher elevations (above 1200′ in particular) get the thickest fog and that slim chance of some patchy ice. That refers to the highest points of Sand Mountain, Lookout Mountain, Cumberland Mountain in Jackson County northward onto the Cumberland Plateau.

Travel north to Nashville Thursday morning may be slick at times; however, roads should remain passable.  You can see the latest road conditions with the TDOT SmartWay Map.

We have some heavy rain and potentially some heavy snow (mainly in Tennessee) coming by Friday.  See the latest expectations and forecast snow amounts here: Rain, some storms, and another winter weather threat.
