Knoxville woke up under a gray, misty blanket Saturday, but the gloom did not last long. Morning fog and low clouds in the valleys thinned out by mid-morning, giving way to steady sunshine and a warmup that will push temperatures into the upper 60s. The valley is expected to top out near 68°F after starting the day in the mid-30s with early visibility around 2 miles.

Afternoon Sun And Shirt-Sleeve Weather

Through the afternoon, expect mostly sunny skies and a high near 68°F, with light southwest winds staying generally calm across the valley. Hourly guidance shows temperatures climbing from the low 40s in the morning into the upper 60s by mid-afternoon. It is the kind of mild, dry day made for tackling errands or getting yard work done without dragging a jacket along, according to the National Weather Service Morristown.

Early-Week Rain Tries To Cut The Party Short

A weak front will slide by late Sunday, bringing a slight chance of showers to the far northern counties. Better rain chances arrive Monday, with around a 40% probability of showers. As the week goes on, showers and a few thunderstorms could redevelop while temperatures climb into the 70s, with some spots potentially reaching the upper 70s by Friday. If your plans stretch past the weekend, especially on Monday, it will be smart to keep an umbrella within reach.

Commute And Weekend Event Outlook

Drivers should still be ready for patchy fog during early Saturday commutes, particularly on bridges and near waterways. Use low beams and allow extra stopping distance to account for the reduced visibility. There are no watches, warnings, or advisories in effect for the area, and the National Weather Service does not anticipate weather-related aviation issues over the weekend. For outdoor plans, Saturday and Sunday afternoons are the sweet spot, but it is worth giving the forecast another look before scheduling events next week.
