Knoxville rolled out of bed to clear, cool skies early Saturday with temperatures hovering around 59°F at local stations. It will not stay that way for long. Under full-on sunshine, readings are expected to surge into the upper 80s by this afternoon. Today stays dry and mostly sunny, a prime window for yard work, hikes, or one last pool day before a run of afternoon and evening storms muscles in early next week.
This Afternoon
Skies turn partly to mostly sunny with a high near 87°F and a light southwest breeze around 0–5 mph. After starting in the mid-60s this morning, temperatures will climb quickly into the mid-to-upper 80s by late day, so keep the water bottle handy if you're outside for long. Hourly guidance keeps rain chances near zero for Saturday.
Sunday Into Next Week
Clouds build on Sunday with highs in the mid-80s and a slight chance of an evening shower, with a few more sprinkles possible Sunday night. A more humid southwest flow settles in as we head into early next week, which bumps up the odds for storms during the afternoon and evening each day.

Storm Timing And Impacts
Monday and Tuesday look to bring the widest coverage of showers and thunderstorms, with rain chances running about 60–80% and the potential for brief heavy downpours. These will be classic hit-and-miss storms: one neighborhood might stay dry while the next one over gets a quick burst of downpours and lightning, so keep a Plan B for evening events. As outlined by NWS Morristown, large-scale forcing appears modest, but moisture is on the increase, which favors short-lived summertime pulse storms rather than a long, soaking, area-wide event.
Plan Ahead
There are no watches or warnings posted this morning, and winds look light through the week, so immediate travel issues should stay on the minor side. That said, drivers should be ready for sudden downpours and slick roads during afternoon commutes early next week. A compact umbrella or light rain jacket thrown in the car now could save you a sprint through the parking lot later. We will pass along any updates if advisories are issued.
