Todays weather in Knoxville TN - Friday - 29 May 2026

Knoxville starts the day in fine form — 86 degrees, partly sunny, light north wind, and that easy early-summer feel that makes you want to stay outside. If you have morning or afternoon plans, today delivers. Sunglasses are a yes; an umbrella stays in the car for now.But tonight flips the script. Storms become likely after 9 p.m., the low drops to 66°F, and rainfall of a quarter to half an inch is expected before morning. No severe weather alerts are in effect, but if you have evening plans outdoors, start watching the sky from around 7 p.m.Saturday carries that storm energy forward — showers and thunderstorms likely through the afternoon, a high near 79°F, and up to three-quarters of an inch of rain possible. Build in extra drive time and keep the wipers ready. Saturday night starts to clear, and Sunday looks like the weekend's reward: partly sunny, a high near 80°F, and only a slight afternoon shower chance.Sunday night brings another storm chance, and Monday heads back into likely-storm territory with a high near 81°F. The pattern this week is rain, clear, rain again — but Tuesday through Thursday breaks the cycle entirely. Mostly sunny skies, low-80s highs, and virtually no rain chance make for a genuinely clean mid-week stretch.Knoxville: enjoy the gorgeous morning, prepare for the stormy night, and know the sunshine on the other side is worth the wait.A YesWee production, built using AI technology.This episode includes AI-generated content.
