Knoxville starts Sunday around 70 degrees, but the easy morning will give way to a high near 93. Winds affecting Knoxville Sunday afternoon were forecast to be generally light and variable.
Sunday Heat Gives Way To A Wetter Monday Night
Sunday carries only a 10% chance of rain, with isolated showers or thunderstorms possible. The overall storm threat is low, but forecasters say a stronger storm could bring damaging winds or a pocket of heavy rain.
Monday will repeat the 93-degree high, with increasing convective activity and a 40% daytime precipitation probability, bringing a substantial chance of showers and thunderstorms. Isolated damaging wind gusts and heavy rain are possible. Rain chances rise sharply Monday night, when storms become likely and the chance of precipitation reaches 60%, according to the National Weather Service in Morristown.
Storms Become Widespread Before Temperatures Break
Tuesday brings a cooler but much wetter setup, with widespread showers and temperatures in the low 80s to low 90s. Wednesday stays rainy and cloudy, with the first sub-90-degree forecast high of the week.
Localized flooding could develop through Wednesday, especially where slow-moving storms repeatedly pass over the same areas. Anyone with outdoor plans should keep an eye on changing skies, and drivers should never attempt to cross a flooded roadway.
Cooler Air Arrives Thursday
Thursday brings a slight chance of showers late in the day, with late-week temperatures ranging from the 70s to 80s. Friday and Saturday bring highs in the 70s to 80s.
