Skies are mostly clear this morning at McGhee Tyson, with temperatures hovering near 73°F. It is already muggy, and that stickiness is not going anywhere through Thursday as highs climb to around 87°F. A few pop-up showers and thunderstorms could bubble up this afternoon, but most neighborhoods will stay dry. Any storm that does form could bring a brief heavy downpour and some gusty wind. Southwest breezes should stay light, around 5–10 mph, so early outdoor plans look workable for most folks.
Afternoon Storms Possible
Scattered showers and a few thunderstorms are most likely from about 11 a.m. through mid-afternoon, with roughly a 30% chance of rain across the metro. Where storms are short-lived, new rainfall totals are expected to stay under a tenth of an inch. Still, a quick downpour could briefly cut visibility on surface streets, so keep an umbrella handy and build in a little extra time for errands or school pickup.
Wet Pattern Builds This Weekend
Rain chances ramp up Friday and stick around into Saturday, with showers and thunderstorms likely. Some spots could see half an inch to three-quarters of an inch of rain in heavier pockets. Forecasters caution that slow-moving or training cells could trigger isolated flash flooding, especially in low-lying areas and across northern suburbs, and a Flood Watch may be needed if current trends hold. Stronger storms could bring gusty winds up to about 20 mph, so plan on damp, occasionally blustery conditions by Friday, as outlined by the National Weather Service in Morristown.
What To Do About Plans
If you are scheduling outdoor events, aim for late morning windows or make sure you have a solid rainy-day backup for Friday night and Saturday. Repeated downpours can cause creeks and drainage ditches to rise quickly. Avoid driving through standing water, secure loose outdoor items, and keep your phone charged with weather alerts enabled.

How To Stay Updated
Before you hit the road, take a look at local radar and the latest updates from the National Weather Service, and watch for any watches or warnings as storms organize. Local broadcasters will roll into continuous coverage if conditions start to go south. If flooding becomes an issue, remember the old rule: turn around, don’t drown, and never drive through flooded roadways. We will share updates if the National Weather Service issues any watches or warnings for the Knoxville area.
