Knoxville is starting Tuesday with clear skies and a cool 40s chill, but the afternoon will feel more like mild fall than winter rehearsal. The high should reach 75 degrees before easing back into the low 70s later, with no rain expected. A light northeast breeze will keep the morning jacket-friendly before sunshine takes over.
The National Weather Service expects mostly clear conditions Tuesday night, with temperatures dropping to around 45 degrees. River fog remains possible near waterways Tuesday, October 20, from 5 to 9 a.m. EDT, but the broader forecast stays dry, calm and favorable for outdoor plans.
Sunshine Holds Through The Weekend
Wednesday should be sunny with a high near 75, followed by sunny skies and highs around 74 Thursday and Friday. The weekend forecast calls for highs in the low-to-mid-70s, compared with the earlier outlook covered by Hoodline, which gave highs of 72 to 73 degrees.
Monday stays mostly sunny with a high near 73, and rain chances remain at zero through the entire forecast period. Overnight lows will generally sit in the mid-40s.
Cool Mornings, Low Humidity And No Alerts
The pattern is a classic fall split shift: chilly starts, comfortable afternoons and plenty of clear sky in between. No watches, warnings or advisories are posted for the Knoxville area, though frost may occur in higher areas.
