Happy Tuesday, East Tennessee! A Comfortable Start with a Warming Trend Ahead – August 5, 2025

Good morning, East Tennessee! It’s Tuesday, August 5, 2025, and as your local meteorologist, I’m rolling out your morning weather update—right now! Happy Tuesday, everybody! Now, let’s talk weather—hope you’re having a great day so far! We’re starting with some mighty comfortable temperatures, with morning lows in the 60s across the region, thanks to that lower humidity that’s been easing in. I hope you’ve had a chance to step outside and enjoy that crisp, refreshing air! As the week goes on, humidity will creep up, bringing a muggy feel, and high pressure will build to push our temps back to seasonal averages. We’ve got some light rain chances midweek, but the end of the week and weekend are looking drier. 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 dive in!

Today, Tuesday: A Pleasant Morning with Showers and Clouds
We’re kicking off this Tuesday with a real treat—morning temps in the 60s, thanks to dew points in the 50s and low 60s that keep the air feeling nice and comfortable, especially near Tri-Cities where it’s still a bit cooler. We had a little fog this morning, but it’s clearing out and shouldn’t slow you down much—perfect for getting the day started! If you’ve got any neat photos from this morning, upload them on the eastTNweather app under Witcher’s Pictures—I’d love to see what you’re capturing! The day will stay mostly cloudy, with some hit-and-miss sunshine trying to peek through, but clouds will thicken as a disturbance rolls our way. This could bring light rain showers later today, mainly across the mountain counties like the Smokies and parts of the valleys, much like we saw yesterday. The good news? We’re not expecting tropical-style downpours since the heavy moisture is parked over the Carolinas and Georgia, and the mid-level energy and spin are mostly to our south and southeast, swinging north. That keeps our rain light, with a 30-40% chance, and no big thunderstorm action due to the cooler air mass lacking instability. Highs should hit the low 80s—our goal from yesterday, though we only made it to the 70s thanks to those cloudier skies. It’s a wash, rinse, repeat kind of day, so if you’re heading to the national park, watch for decent rain on the highest peaks.

The Rest of the Story: Wednesday Through Sunday
Looking ahead, Wednesday, August 6, will echo today. Morning lows will stay in the 60s, keeping that comfortable start, but humidity will tick up, adding a slight stickiness. Highs will again reach the low 80s, with mostly cloudy skies and a chance for passing showers—light stuff, nothing to worry about too much, as the disturbance lingers. The pattern holds steady.

Thursday, August 7, through the weekend—Saturday, August 9, and Sunday, August 10—will shift as high pressure builds back in. This will warm our highs to seasonal averages, likely hitting the mid-80s to low 90s by Sunday, with rising humidity pushing the heat index toward 95-100°F. Rain chances will drop off, trending drier as the ridge takes over, though a stray shower might sneak in. It’ll feel a bit muggy, but it’ll be a nice lake weekend compared to July’s heat.

The Rest of the Forecast: Next Week and Beyond
Next week, that high pressure will strengthen, locking in warmer weather with highs climbing to the low to mid-90s and heat index values nearing 100-105°F as humidity builds. Rain chances will stay low, with only isolated afternoon showers possible, mostly along the Smokies and Cumberland Plateau where lift might spark a sprinkle. The Climate Prediction Center suggests this warmer, drier trend could last 7-10 days, with temps near or above average and rainfall below normal—classic late summer.

Looking toward mid-to-late August, the pattern might see some gentle shifts. Highs could rise to the upper 80s to mid-90s, with heat index values around 95-100°F as humidity stabilizes. Afternoon storms will pick up, driven by summer heat and disturbances, offering a mix of sun and rain. A weak front might bring a brief cool-down or rain boost, but no big changes are looming. For Knoxville locals, Chattanooga outdoor fans, and Smoky Mountain visitors, this means enjoying today’s cool start, prepping for light rain midweek, and looking forward to a drier, warmer weekend.

Tropical Update: Eyes on the Tropics
Let’s check the tropics! We’re building toward peak hurricane season on September 10, and things are ramping up. Tropical Storm Dexter is out in the Atlantic, a ‘fish storm’ heading toward Bermuda and New England—nothing to worry about here. The National Hurricane Center is watching a system off the southeastern coast with a 30% chance of becoming our next named storm (maybe Aaron, then Ferdinand or Gabrielle) over the next 7 days—likely not much. A wave off Africa has a 50% chance, and models hint it could approach the U.S. by next week’s end, but it’s too early for solid predictions—watch social media, but don’t trust those far-out model runs yet! It’s right on track for August hurricane formation, and as we head into September, expect more activity. I’ll keep you updated daily!
