Knoxville started Sunday, July 5, in something of a daze, with patchy fog and mist reported across the area and temperatures hovering near 73°F. Visibility dropped to around 1 mile in spots, and with dew points in the low 70s, the air is already thick and muggy. The fog should thin out by mid‑morning, clearing the way for a quick warmup into the low 90s by afternoon.
Afternoon Heat And Storm Timing
By Sunday afternoon, expect mostly sunny skies and a high near 92°F, with heat‑index values pushing close to 100°F in the hottest neighborhoods. A late‑day round of showers and thunderstorms is on the table, with forecasters at NWS Morristown calling for about a 30% chance of storms during the day and higher odds into the evening. Any stronger cells could deliver brief downpours and gusty winds. Light west breezes around 0 to 5 mph mean storms should stay scattered, often bubbling up over the higher terrain before drifting into the valleys.
Cooling Centers And Heat Safety
With highs in the low 90s paired with sticky humidity, cooling centers are open around the city for anyone who needs a break from the heat. Local resources list Knox Area Rescue Ministries at 418 N Broadway and the Volunteer Ministry Center at 511 N Broadway as options; be sure to confirm hours before you go, according to WVLT. If you plan to be outside, hydrate often, avoid the most strenuous activity during the mid‑afternoon, and make sure pets and vulnerable neighbors have access to shade and air‑conditioned or cooled spaces.
Looking Ahead
Monday, July 6, keeps the warm pattern going, with a high near 90°F and another round of afternoon and evening showers and thunderstorms possible. Storm chances look to stay tied to the daytime heating through the week, with guidance hinting at a possible uptick in storm coverage later in the week into the weekend, so it is smart to have a backup plan for outdoor events. Keep an eye on updated forecasts and radar if you have anything scheduled outside over the next several days.
