Good morning, East Tennessee! It’s 09:29 AM EDT on Saturday, August 2, 2025, and as your local meteorologist, I’m rolling out the latest weather update—right now! Welcome to the weekend, my friends! Unfortunately, I hate to be the bearer of bad news this weekend. While it’s going to be great because we’ll have cooler-than-average temperatures, the clouds are sticking around, and the chance for rain is increasing. We’ve already had some showers to get the day started, but it does feel pretty good across the Tennessee-Kentucky border where all our temperatures are trending cooler than yesterday morning—and that’s all thanks to the lower humidity settling in. So again, enjoy it! This easy-to-grab blog dives deep into today’s forecast for Knoxville, Chattanooga, and the Great Smoky Mountains, then lays out the rest of the story in detail—so let’s jump in and get ready!
Today, Saturday: A Refreshing Start with Clouds and Rain Today
We’re kicking off this Saturday with a treat—temps in the low 60s this morning, a crisp and comfortable start thanks to that lower humidity finally kicking in after the cold front. By now, at 9:29 AM EDT, we’re warming slightly into the upper 60s, and the clouds are thick overhead, a sign of what’s to come. Those clouds will stick with us all day, driven by an inverted trough—a weather pattern where low pressure stretches horizontally across the region, pulling in moisture and keeping the skies overcast while encouraging rain to develop. We’ve already seen some early showers, and more are on the way this afternoon, especially along the mountain counties like the Smokies and Cumberland Plateau. The Weather Prediction Center has us under a Level 1 and 2 risk for localized flash flooding concerns, so watch for heavy downpours that could lead to wet spots or puddles. Highs will stay below average, topping out in the low 80s—our norm is 88°F this time of year—thanks to the cloud cover and that troughing taking shape. It feels great out there, so enjoy it, but stay prepared.

The Rest of the Forecast: Next Week and Beyond
Next week, the weather story continues with more clouds, cooler highs, comfortable lows, and elevated rain chances. Monday and Tuesday will see that troughing persist, keeping the skies mostly overcast, but drier air will start to filter in, shutting down the rain chances for a bit. Highs will stay in the low to mid-80s, with lows dipping into the 60s, offering that below-average, refreshing feel we’re enjoying now. The heat index will hover around 85-90°F, a far cry from the triple-digit days we’ve left behind.
By Wednesday through Friday, a deeper trough will dig across the state, ramping up the cloud cover and increasing rain potential again. We could see scattered showers and possibly a thunderstorm or two, with rainfall amounts staying modest but enough to keep things green. Highs will hold in the mid-80s, and lows will stay in the comfortable 60s, with humidity rising slightly but not returning to the muggy levels of July. The Climate Prediction Center hints this cooler, wetter pattern could stretch into the next 7-10 days, with temperatures and precipitation trending below and above average, respectively—a nice shift for late summer.
Looking toward mid-August, the pattern should ease into a more typical late-summer flow. Highs will likely creep up to the upper 80s to low 90s, with heat index values settling around 95-98°F as humidity starts to rebound. Afternoon storms will become more frequent, driven by summer heat and passing disturbances, offering a balanced mix of sun and rain. The trough’s influence might wane, but no major heat waves are on the radar yet, and the recent cool-down should keep things manageable. If a stronger front moves in, we could see another dip, but for now, expect a pleasant stretch with occasional showers. For Knoxville locals, Chattanooga outdoor fans, and Smoky Mountain visitors, this means savoring today’s cooler vibe, planning around weekend rain, and enjoying a mild week ahead.
ABOVE AND BEYOND THE 7 DAY FORECAST
Why This Weather is Happening
That refreshing start and cooler temps come from a cold front that’s brought lower humidity, breaking the heat wave we’ve endured. The inverted trough—low pressure stretching out and pulling in moisture—is keeping clouds and rain in play, while the front’s influence keeps us below average. It’s a classic summer transition—cooler now, with a wet twist, but a welcome change. Stay alert!
