Knoxville is starting Monday under mostly cloudy skies, calm winds, and muggy air, with temperatures near 72 degrees around sunrise. The day should warm to about 84, but the more immediate forecast is a growing chance of showers and thunderstorms from late morning through the afternoon.
Storm Chances Rise Around Lunch
A slight chance of a shower or storm arrives between 11 a.m. and 1 p.m., with rain chances increasing after 1 p.m. and reaching about 50% during the afternoon. North winds will stay light at 0 to 5 mph, according to the National Weather Service.
A few locations could see very heavy rainfall, and localized flooding is possible because the ground is already wet from recent rain. Most new rainfall should remain below a tenth of an inch, but isolated downpours could still create quick trouble on roads and in low-lying areas.
Quieting Down Monday Night
Showers and thunderstorms remain possible before 7 p.m., followed by a slight chance through 8 p.m. Skies should turn partly cloudy overnight, with a low near 68 and northeast winds around 5 mph.
Storms Keep Showing Up This Week
Tuesday brings mostly sunny skies early and a high near 87, followed by a 60% chance of showers and thunderstorms from midafternoon into the evening. Wednesday looks wetter, with showers possible in the morning and storms likely later, a high near 86 and another 60% rain chance.
Thursday through Sunday look warmer, with highs around 88 each day and mostly sunny stretches interrupted by afternoon or evening storm chances ranging from 30% to 50%. Overnight lows should stay mostly in the upper 60s to low 70s, making outdoor plans a bit of a gamble all week.
What Knoxville Readers Should Watch
The main concern is not an all-day washout but isolated heavy downpours that could overwhelm drainage in spots. Keep an eye on darkening skies through Wednesday, avoid driving through water-covered roads, and move indoors if thunder is nearby; no watches, warnings or advisories are posted for the area at the latest update from the National Weather Service.
