Nashville, Tennessee – Drivers across Middle Tennessee face sudden drops in visibility to one-quarter mile or less along Interstate 40 and Interstate 24 through 10 a.m. Friday, creating hazardous conditions for the morning commute. Fog has thickened across the Cumberland Plateau and pockets of low-lying areas, leading to rapid changes in visibility within seconds.
According to the National Weather Service in Nashville, a Dense Fog Advisory remains in effect until 10 a.m. CST for much of Middle Tennessee. Visibility in some locations has fallen to 500 feet or less, particularly east of Nashville toward Cookeville and Crossville. The advisory includes major corridors such as I-40, I-24 and portions of I-65, where traffic volume increases during peak commute hours.
On the Cumberland Plateau, fog is especially dense along elevated stretches of I-40, where cooler air traps moisture near the surface. Clarksville and areas near the Kentucky state line are also reporting reduced visibility along I-24. Transportation officials urge drivers to slow down, use low-beam headlights and avoid sudden braking. Allow extra following distance and prepare for abrupt slowdowns near interchanges and river crossings.
Conditions will steadily improve after 10 a.m. as sunshine returns and temperatures climb into the 60s Friday afternoon. A quiet and mild weekend is expected across Nashville, Murfreesboro and Columbia once the fog lifts.
Drivers should remain alert through midmorning, as visibility can fluctuate block by block. Additional advisories are possible if fog lingers longer than expected in plateau communities.
