Knoxville is starting Saturday clear and chilly, with temperatures around 44 degrees before a quick warmup. Sunshine will push the afternoon high near 73, and no rain is expected.

Chilly Starts, Sunny Afternoons

Saturday night will stay mostly clear, with temperatures falling to around 44 degrees and light northeast winds. Patchy fog remains possible near rivers and lakes during the early morning hours over the next several days, according to the National Weather Service.

Sunday will bring another sunny afternoon near 74, followed by a low around 43 Sunday night. Monday stays sunny and mild near 73, making the weekend-to-workweek forecast unusually friendly for outdoor plans.

Dry Stretch Runs Into Friday

Tuesday should reach 74 degrees under mostly sunny skies, while Wednesday turns mostly cloudy but remains warm near 74. Thursday will be sunny with a high near 75, and Friday's high is expected to reach 76.

The updated outlook now carries Knoxville's dry spell through Friday, extending the pattern covered in Hoodline's previous forecast. Afternoon humidity will stay on the low side, but light winds should limit notable fire-weather concerns, and no watches, warnings or advisories are listed for the area.

For residents heading out early, a jacket will still be useful, especially near waterways where fog can briefly reduce visibility. By afternoon, though, the forecast is firmly in patio-and-park territory, with mild temperatures and plenty of sunshine.
