Knoxville is getting a late-summer reset Sunday: clear skies, a cool start near 68°F, and a sunny afternoon topping out near 87°F. The air should feel less sticky after a cold front moved through overnight, with light north winds keeping conditions calm. There are no active weather alerts for the area.
Sunny Sunday, Cooler Night
The National Weather Service in Morristown forecasts no rain Sunday, with temperatures climbing through the 70s and into the mid-80s during the afternoon. North winds should remain light at 0 to 5 mph. Patchy fog may linger in a few spots early, but sunshine is expected to take over.
Sunday night will turn partly cloudy, with temperatures dropping to around 61°F. That cooler overnight air should make for a noticeably more comfortable evening than Knoxville's recent muggy stretches.
Quiet Start To The Week
Monday stays mostly sunny with a high near 86°F and a low around 60°F. Tuesday will be sunny and slightly warmer, reaching about 88°F before dipping to near 63°F overnight. Rain chances remain essentially zero through Tuesday, giving outdoor plans a clean weather window.
Storm Chances Return Wednesday Night
The pattern shifts Wednesday night, when a 40% chance of showers and thunderstorms arrives after about 8 p.m. and continues into the overnight hours. Thursday brings another chance for showers and thunderstorms, with precipitation odds around 50% and a high near 89°F.
Friday and Saturday stay mostly sunny and hot, with highs near 89°F to 90°F, but each day carries a slight 20% chance of afternoon or evening showers and thunderstorms. For now, the best stretch for dry outdoor plans runs from Sunday through Tuesday, before the forecast gets more unsettled midweek.
