Nashville, Tennessee – Drivers across Middle Tennessee should be prepared for sharply reduced visibility overnight as dense fog develops and lingers into the Wednesday morning commute, creating hazardous travel conditions across the region.
According to the National Weather Service in Nashville, clear skies and calming winds tonight will allow fog to form after midnight, becoming widespread by early Wednesday morning. Visibility is expected to drop below one mile in many areas, with pockets of dense fog reducing visibility to a quarter mile or less. The highest probabilities stretch across Nashville, Murfreesboro, Clarksville, Columbia, Cookeville, and surrounding communities.
The fog threat extends beyond urban areas, with rural highways and low-lying valleys especially vulnerable to sudden visibility drops. Interstates including I-24, I-40, and I-65 could see rapidly changing conditions, particularly during the early commute window. Motorists may encounter fog thick enough to obscure traffic signals, exits, and stalled vehicles with little warning.
Officials urge drivers to slow down, increase following distance, and use low-beam headlights. High beams can reflect off fog droplets and further reduce visibility. Extra caution is advised near rivers, lakes, and open fields where fog often becomes densest.
The National Weather Service says fog should gradually lift by mid to late Wednesday morning as temperatures rise and light winds return. Until then, travel impacts remain likely, and additional statements may be issued if dense fog becomes more widespread or persistent.
