East Tennessee Weather: Sunshine Returns Tuesday, Dry Midweek, and Rain Chances Loom for the Weekend

Happy Tuesday, East Tennessee!
On this June 10, 2025, at 7:41 AM EDT, we’re celebrating a glorious return to sunshine as the rain finally takes a break—time to rejoice! A Dense Fog Advisory blankets the Cumberland Plateau this morning, but clear, warm skies are on the horizon. From the lively streets of Knoxville to the tranquil trails of the Great Smoky Mountains and the rugged Cumberland Plateau, the EastTNweather platform, led by meteorologist Mike Witcher, delivers hyper-local updates via its app, website, YouTube, Roku, Amazon Fire, and Apple TV to keep you in the know. 

Tuesday: Sunshine Breaks Through Morning Fog
Tuesday dawns with patchy dense fog across East Tennessee, especially under a Dense Fog Advisory for the Cumberland Plateau, where visibility could dip below a quarter-mile in spots like Crossville, Jamestown, and Harriman. Morning temperatures start in the 60s, with dew points in the low 60s offering a less muggy feel compared to the upper 60s and low 70s of recent days. Behind a cold front, drier air filters in, setting the stage for a comfortable summer day. By mid-morning, the fog burns off, giving way to abundant sunshine that pushes lunchtime temperatures into the mid to upper 70s. Afternoon highs soar to the mid to upper 80s, 3-5 degrees above the seasonal average of 81°F, with a heat index hovering around 85-88°F due to moderate humidity.

The EastTNweather app is your essential tool for navigating morning fog and planning outdoor fun, with its Interactive Radar confirming clear skies after 9-10 AM. Seize the sunshine for morning hikes in Cades Cove, picnics at Knoxville’s Ijams Nature Center, or riverside strolls in Chattanooga, but drive cautiously in foggy areas like the Cumberland Plateau until the advisory lifts. South of I-40, including Chattanooga and Cleveland, expect rapid fog clearance, perfect for outdoor dining in Pigeon Forge or exploring Gatlinburg’s vibrant streets. North of I-40, like Knoxville and Morristown, the sun shines bright for markets or festivals in Jonesborough. Tuesday’s warm, sunny weather is a summer delight, so get out and enjoy!

Wednesday: Dry, Sunny and Warm
Wednesday keeps the summer vibes rolling with dry, sunny conditions and highs in the mid to upper 80s, aligning with Tuesday’s warmth. Lows dip to the 60s overnight, offering pleasant mornings, especially in higher elevations like the Cumberland Plateau. Dew points hold steady in the low 60s, keeping humidity comfortable and the heat index near the actual temperature, around 85-88°F. Clear skies prevail, with no rain in sight, making it another stellar day for outdoor adventures across East Tennessee’s diverse landscapes.

The EastTNweather app’s forecasts ensure you capitalize on Wednesday’s pristine weather, with updates confirming dry skies. Plan kayaking on the Tennessee River, visiting the Knoxville Zoo, or enjoying concerts in Chattanooga, but pack sunscreen and stay hydrated in the mid-80s. The app’s hyper-local precision is ideal for scheduling hikes in the Smoky Mountains, commutes in Sevierville, or outdoor events in Athens, with both north and south of I-40 basking in sunshine. The platform’s streaming updates on YouTube, Roku, Amazon Fire, and Apple TV, led by Mike Witcher, provide context for this dry midweek stretch, keeping your summer plans vibrant and safe. Wednesday’s sunshine is a perfect excuse to explore East Tennessee’s beauty!

Thursday: Mostly Sunny with Isolated Storm Chances
Thursday maintains the warm, sunny trend, with highs in the mid to upper 80s and lows in the 60s, but a slight chance for isolated afternoon storms creeps in. Dew points begin to rise toward the mid-60s, hinting at increasing humidity by week’s end. These storms, if they develop, are expected to be spotty, with rainfall under 0.25 inches and a low risk of severity, most likely south of I-40 in Chattanooga or Cleveland after 3 PM. The vast majority of East Tennessee, including Knoxville and Upper East Tennessee (Johnson City, Kingsport), should stay dry, supporting outdoor plans.

The EastTNweather app’s Interactive Radar is your go-to for monitoring Thursday’s potential storms, with real-time tracking to confirm dry conditions for most areas. Enjoy afternoon hikes in the Cumberland Plateau, outdoor dining in Pigeon Forge, or festivals in Morristown, but check the app for late-day shower updates south of I-40. The platform’s streaming updates refine Thursday’s outlook, ensuring you can plan confidently. Thursday’s mostly sunny skies keep the summer momentum strong, with the app keeping you prepared for any stray showers.

Friday-Sunday: Rising Rain Chances
Friday through the weekend, a weather shift arrives as a wave moves out of Texas toward the Ohio Valley, elevating rain chances across East Tennessee. Highs will hold in the mid to upper 80s, with dew points climbing to the upper 60s and low 70s, pushing the heat index to 90-95°F and bringing back muggy conditions. Scattered showers and storms are expected, with rainfall totals of 1-2 inches possible by Sunday, heaviest south of I-40 in Chattanooga, Cleveland, and Athens. North of I-40, including Knoxville and Morristown, may see lighter amounts but still face wet spells. Localized flooding risks could emerge in urban areas like Knoxville’s downtown or low-lying regions near the Little Pigeon River in Sevierville, especially if storms train over the same areas. Severe weather risks remain uncertain but could include gusty winds.

The EastTNweather app’s long-range forecasts and Interactive Radar are critical for tracking this weekend’s evolving weather, with push notifications for heavier rain or potential severe storms. Plan indoor backups like the Tennessee Aquarium in Chattanooga or Dollywood’s indoor attractions in Pigeon Forge for Saturday afternoons. Use the app to find dry windows for morning hikes in Gatlinburg or markets in Jonesborough, particularly north of I-40. The platform’s streaming updates, led by Mike Witcher, will sharpen the weekend forecast as details solidify, so check back before Friday for the latest. The wet weekend keeps summer dynamic, but the app ensures you stay flexible and safe.

Next Week Outlook: Active Summer Weather
Early next week, the active summer pattern persists, with highs in the low to mid-80s and scattered afternoon showers or storms, though less widespread than the weekend. Dew points in the mid-60s maintain moderate humidity, with rainfall amounts under 0.5 inches per storm. This weather supports outdoor activities like visiting the East Tennessee History Center in Knoxville or kayaking in Chattanooga, but flexibility is key to dodge showers. The EastTNweather app’s extended forecasts will refine next week’s outlook, with alerts for any renewed severe risks.

The platform’s streaming updates on YouTube and Roku provide context for the long-range forecast, helping you plan commutes in Morristown or events in Sevierville. The low to mid-80s offer a vibrant summer feel, with the app’s precision ensuring you seize dry moments for hikes in the Smoky Mountains or concerts in Cleveland. Stay tuned to the app for updates as the week unfolds, keeping your summer plans on track and weather-ready.
