Knoxville woke up in a haze Monday, July 6, 2026, with fog and mist hanging low, temperatures near 72°F and patchy visibility in the hollows. By this afternoon, the mercury is expected to climb into the upper 80s to near 90°F, with heat index values pushing about 96. Showers and thunderstorms are expected to pop up later in the day, especially during the peak heating hours.
Foggy Mornings, Stormy Afternoons
The early patchy fog should fade by mid-morning, but storm chances go the other direction as the day wears on. Showers and thunderstorms are expected to become more common through the afternoon, with the most active window roughly between 2 and 6 p.m.
Any stronger cell could drop a quick burst of heavy rain, which may lead to brief ponding on roads and in low-lying spots. The National Weather Service in Morristown is flagging an elevated risk for urban and small stream flooding if storms slow down or repeatedly move over the same areas. According to the National Weather Service in Morristown, storms should remain scattered and mainly driven by daytime heating, but slow storm motion means a few neighborhoods could see locally heavy totals.
Heat, Humidity And Cooling Options
Even with storms around, it will stay hot and sticky, with highs near 90°F and a muggy feel lingering into the evening. Hydrate, take breaks in the shade, and try to avoid the most strenuous outdoor work during midafternoon.
The city and partner groups have opened cooling centers and other public air conditioned spots across Knoxville. Location lists and hours are available from WVLT. If you rely on one of these sites to cool off, call ahead or double-check the provider’s page before heading out, since hours can shift.
Plan For Outdoor Activities
If you have outdoor plans for Monday afternoon, July 6, 2026, it might be wise to move them earlier or at least build a weather backup plan. Storm chances are highest from about 2 to 6 p.m., and the main hazards are lightning and gusty microbursts.
General winds are expected to stay light, around 0 to 5 mph, but stronger storms could kick up localized gusts and knock down small limbs. At the first rumble of thunder, head indoors and stay away from flooded roads, since even shallow water can hide washouts or debris.
