Knoxville is starting Wednesday, May 27, 2026, on the sticky side, with cloudy skies, temperatures around 70°F, and a dew point close to 70°F, making it feel pretty soupy out the door. Spotty showers are possible before midday, but the main action arrives late morning into the early afternoon. Highs should top out near 82°F with a southwest breeze around 5 to 10 mph. If you are out for the midday commute, plan on rain gear, since coverage looks isolated to scattered rather than an all-day washout.
Afternoon Storm Window
According to the latest forecast discussion from the National Weather Service Morristown, there is a chance of rain before 11 a.m., with the best shot at showers and thunderstorms between about 11 a.m. and 3 p.m. Hourly rain chances peak in the mid-afternoon. The overall severe threat is limited, but any stronger cell could bring a quick burst of heavy rain, frequent lightning, and brief ponding in low spots.
Commute And Outdoor Plans
Drivers should expect wet pavement and slower going around the midday and early afternoon commute, since even short, intense downpours can turn low-lying streets into trouble spots. If you have outdoor practices, lunches, or events lined up, it is smart to move them under cover or push them back to later in the day, when drier breaks are more likely. This update trims coverage slightly from the broader midday rain threat highlighted yesterday.
Rest Of The Week
Scattered showers and storms remain in the mix through Thursday, although forecasters expect longer dry stretches as the week wears on. A more widespread batch of showers and thunderstorms may swing through on Friday for parts of the region. Daytime highs should hold in the upper 70s to low 80s, with overnight lows in the low to mid 60s through the weekend. Keep weather alerts turned on and check for updates before you head out, since the timing and coverage could still wobble if a slow-moving cell sets up.
