Knoxville-area drivers rolled out early Friday, February 27, 2026, into pockets of dense fog that briefly cut visibility to about a quarter mile in low-lying neighborhoods and river valleys. The good news: the gray start will not last. The fog is expected to lift through midmorning, giving way to clear skies, sunshine, and a mild afternoon high near 63°F with light winds, setting up an easy afternoon commute and comfortable outdoor plans across the valley.
Morning Fog and Travel
According to the National Weather Service Morristown, a Special Weather Statement issued at 6:51 a.m. warned that visibility could drop to one-quarter mile or less through about 9:00 a.m. Drivers are urged to slow down, use low-beam headlights, and leave extra stopping distance, especially on bridges and near waterways. Conditions should improve quickly as drier air mixes in and the boundary layer warms.
Afternoon Into The Weekend
Sunshine returns this afternoon with a high near 63°F, and the mild, dry pattern is expected to hold through the weekend with highs around 67°F on both Saturday and Sunday. A slight chance of showers moves back in late Sunday night into Monday, with about a 40% chance of rain on Monday, then temperatures climb into the 70s by midweek and could reach the mid-70s by Thursday.
