Nashville, Tenn. – Thick fall fog will blanket much of Middle Tennessee overnight, prompting the National Weather Service in Nashville to issue a Dense Fog Advisory for the entire region from midnight through 10 a.m. Monday. Visibility may drop below one-quarter mile at times, especially in valleys and along river corridors.
According to the NWS, fog will form quickly after midnight as skies clear and temperatures fall into the low 40s. The advisory covers all Middle Tennessee counties, including Davidson, Montgomery, Rutherford, Sumner, Maury, and Williamson. Motorists traveling along major routes such as I-24, I-40, I-65, and I-840 should prepare for sudden drops in visibility and slick spots on bridges and overpasses during the Monday morning commute.
The dense fog is expected to linger through mid-morning before gradually lifting as the sun rises and temperatures warm. Patchy fog may persist longer in rural areas and near waterways such as the Cumberland and Duck Rivers.
Drivers are urged to slow down, use low-beam headlights, and increase following distance. School buses and early commuters may experience delays across Nashville, Murfreesboro, Clarksville, and surrounding areas. Emergency officials recommend allowing extra travel time and avoiding distractions until visibility improves.
Conditions will improve by late morning, giving way to a mild and dry afternoon with highs near 66°F. However, additional overnight fog is possible again Monday night if winds remain light and skies stay clear.
