Knoxville is waking up under a blanket of clouds this morning, with temperatures near 57°F and some sticky humidity hanging around. Skies should turn partly sunny later in the day, and the high will climb to around 78°F. A cold front arrives this afternoon, though, bringing a chance of showers and thunderstorms after about 3 p.m. Any stronger cells could pack gusty winds and quick-hitting downpours.
Afternoon Storm Risk
Showers and a few thunderstorms are most likely this afternoon and evening, with the best odds across northern areas and higher elevations. According to the National Weather Service in Morristown, the primary concern is gusty or potentially damaging straight-line winds, with gusts up to 25 mph possible in stronger storms. The nearby marginal severe outlook from the Storm Prediction Center reflects some uncertainty about how organized these storms will get.
Commute And Events
If you are heading out this afternoon or evening, it is a good idea to leave a bit earlier and have a backup plan for outdoor activities. Brief heavy downpours could make roads slick and cut down visibility, and gusty winds may toss around loose patio furniture or small branches. Event organizers and outdoor workers should keep an eye on the sky and be ready to hit pause if lightning or strong winds roll in.
Rest Of Week
Thursday turns noticeably cooler, with highs in the low 70s and some chilly nights. In the higher terrain, overnight temperatures could dip into the 40s. By the weekend, the pattern flips as a ridge builds in, pushing highs back into the upper 80s to around 90°F by Sunday and early next week. That will ramp up heat stress for outdoor plans, so it is worth checking in on later forecasts if you will be outside for long stretches.
Stay Updated
Before you travel, check the latest forecasts and radar, and secure loose outdoor items if storms move through so they do not turn into projectiles. Local updates will be posted by the National Weather Service and county emergency channels as needed.
