Knoxville woke up socked in under fog and mist Friday, with the metro area looking more like a mountain ghost town than the start of a summer-feel weekend. As of 6:15 AM EDT Friday, June 5, 2026, local observations showed dense fog, temperatures near 59°F, a matching dew point around 59°F, and visibility trimmed down to roughly one mile. The murk should thin by mid-morning, opening the door to mostly sunny skies and an afternoon high near 85°F.
Afternoon Outlook
Once the fog burns off, expect a calm, bright stretch to take over. Light west winds around 0–5 mph will barely stir the air while the sun does the heavy lifting, pushing temperatures into the mid 80s. Look for highs around 85°F in the city, with spots farther inland running a touch warmer. This forecast comes from the National Weather Service Morristown; check the office's local forecast if you want hour-by-hour planning details.
Weekend Heat And Humidity
Saturday cranks things up a bit more, with highs near 87°F and overnight lows only dipping into the mid 60s. A southwesterly flow will start feeding more moisture into the Tennessee Valley, and by Sunday the humidity will catch up, even though the high holds near 87°F. Expect a few stray afternoon clouds to bubble up as that muggy air settles in. For background on how this sticky setup is building in, see our coverage of the developing muggy pattern.
Storms Return Next Week
Rain chances stay low through Saturday, but the quiet stretch starts to fray on Sunday afternoon and into next week. Forecasts and model guidance show about a 50% chance of showers and thunderstorms on Monday and around a 60% chance on Tuesday. Any storms should be scattered and hit-and-miss, focused mainly during the warmer afternoon and evening hours. As of now, Tuesday and Wednesday are lining up as the most likely days for more widespread activity. If you have outdoor plans next week, plan on keeping an eye on radar and be ready to dodge brief heavy downpours and lightning.
Plan And Safety
If you are heading out in the early hours Friday, allow a little extra commute time while the fog lifts and keep your low beams on to cut through the soup. Most weekend events should be in good shape through Saturday afternoon, with sunshine and dry weather cooperating. By Sunday afternoon and into next week, have a backup plan ready in case storms roll through and cause scattered delays. We will update this post if the National Weather Service issues any watches or advisories.
