Knoxville is waking up under a blanket of clouds this morning, with temperatures in the mid-60s and a far more reasonable feel than last week’s swampy stretch. The sun is expected to break through as the day goes on, pushing Monday, June 15, highs to around 81°F. Light northwest breezes at 0 to 5 mph should keep things comfortable for midday errands, patio lunches, and anyone trying to squeeze in a walk before the real summer steam returns later in the week. After this brief cooler, drier spell, a wetter and windier system is on track to move in Thursday into Friday.
Afternoon And Tonight
This afternoon looks mostly sunny with a high near 81°F, followed by a partly cloudy night and a low around 60°F. Winds stay light and
chances remain minimal across most neighborhoods, so evening plans are in good shape. This short-term outlook comes from the National Weather Service.
Midweek Warm‑Up
By Wednesday, June 17, the cooler air steps aside. Highs climb to around 87°F, and southwesterly winds start to pick up. Gusts could reach 20 to 30 mph on Wednesday night as those breezes strengthen. That warm, blustery setup is the classic pregame for more organized rain later in the week, a pattern first spotlighted in our earlier look at how swampy Knoxville sizzles.
Thursday And Juneteenth Outlook
Showers and thunderstorms are likely on Thursday, June 18, with the chance of rain jumping to around 80% in the afternoon and staying high into Thursday night. Southwest winds of 15 to 20 mph are expected, with gusts that could reach 35 mph. Friday, June 19 (Juneteenth) is shaping up to be a wet one too, with storms possible before mid-afternoon and outdoor events facing a decent shot of disruption. Heavy downpours may cause quick ponding on city streets and cut visibility, so organizers are urged to move gatherings indoors or have a solid backup plan ready, according to the National Weather Service.
Plan Ahead
With storms lining up late week, keep tabs on local alerts and build in extra travel time for Thursday and Friday. Tie down or bring inside lightweight outdoor items before the wind kicks up, and keep umbrellas and rain jackets within arm’s reach. If you are planning a Juneteenth celebration, consider shifting it under cover or rescheduling so you are not racing a thunderstorm to the grill.
