Stormy Sunday, June Heat Midweek, and Showers Return Late Week

Happy Sunday, my friends in East Tennessee! On this June 1, 2025, at 8:48 AM EDT, we’re diving into a dynamic summer day with a stormy outlook, as an upper-level wave brings a risk of strong to severe storms this afternoon. From the vibrant streets of Knoxville to the lush trails of the Great Smoky Mountains and the rugged Cumberland Plateau, today’s weather demands attention, but a sunny, hot stretch is coming midweek. The EastTNweather platform, led by meteorologist Mike Witcher, delivers hyper-local updates via its app, website, YouTube, Roku, and Amazon Fire  to keep you safe and informed. 

Sunday: Stormy Afternoon with a Severe Weather Risk
Sunday starts with partly cloudy skies and comfortable morning temperatures in the 60s, but an upper-level wave sliding through during peak heating (1-5 PM EDT) will spark showers and storms across East Tennessee. Forecast highs reach the mid to upper 70s, near the seasonal average of 81°F, with dew points in the mid-60s creating a muggy feel. The atmospheric dynamics favor storm development, and some storms could become strong to severe, with damaging winds (up to 60-70 mph) as the primary threat. Small hail (up to 1 inch) is also possible, particularly south of I-40 in Chattanooga, Cleveland, and Athens, though Upper East Tennessee (Morristown, Kingsport) also faces a severe risk. Rainfall amounts will range from 0.5-1 inch in storm-hit areas, but widespread flooding is unlikely.

The EastTNweather app is your lifeline today, with its Interactive Radar offering past, current, and two-hour future projections to track storm timing. Plan morning activities like picnics at Knoxville’s Tyson Park or hikes in Cades Cove, but monitor the app for afternoon storm alerts, especially after 1 PM. South of I-40, secure outdoor items in Chattanooga for potential wind gusts, and have indoor backups like the Tennessee Aquarium ready. North of I-40, including Knoxville and the Smoky Mountains, use the app to find dry windows for short outings, but avoid outdoor plans during peak storm hours. The app’s hyper-local forecasts and severe weather alerts ensure you stay safe, making Sunday’s storms manageable with vigilance.

Monday through Wednesday: June Heat Takes Over
Monday through Wednesday bring a welcome shift as a ridge of high pressure builds in, delivering solid June heat and sunny, dry conditions. Highs will soar into the mid to upper 80s, 5 to nearly 10 degrees above the seasonal average, with heat index values in the low to mid-90s due to dew points in the mid to upper 60s. Lows will hover in the 60s, keeping nights warm. This dry, hot stretch is a refreshing break from the recent rainy spell, perfect for outdoor activities across East Tennessee after a wet May. The sunny skies and summer-like warmth invite residents to embrace the season’s vibrancy.

The EastTNweather platform’s streaming updates on YouTube, Roku, Amazon Fire, and Apple TV, led by Mike Witcher, provide context for this hot stretch, while the app’s forecasts help you plan outdoor fun. Enjoy kayaking on the Tennessee River, visiting the Knoxville Botanical Garden, or attending concerts in Chattanooga, but stay hydrated and apply sunscreen in the mid to upper 80s. The app’s hyper-local precision ensures you maximize these dry days, ideal for hikes in the Cumberland Plateau or festivals in Pigeon Forge. North of I-40, including Knoxville and Morristown, will feel the heat most intensely, while southern areas like Chattanooga may see slightly cooler highs. This June heat sets the stage for a vibrant summer kickoff.

Thursday through the Weekend: Showers and Storms Return
The pattern shifts again by Thursday as a trough develops over the Rockies and moves eastward, pushing a cold front through East Tennessee. This will bring an increased threat of showers and storms from Thursday through the weekend, with rainfall amounts of 0.5-1.5 inches possible, heaviest south of I-40 in Chattanooga, Cleveland, and Athens. Highs will remain in the low to mid-80s, with lows in the 60s and muggy dew points in the mid-60s fueling storm development. Storms could bring gusty winds and small hail, but severe risks will depend on the front’s timing, which the EastTNweather app will track closely.

The app’s Interactive Radar is essential for monitoring Thursday-Friday storms, with push notifications alerting you to heavier showers. Plan indoor activities like the East Tennessee History Center or Dollywood’s indoor attractions during peak storm hours, especially south of I-40. North of I-40, including Knoxville and the Smoky Mountains, use the app to find dry windows for hikes in Gatlinburg or commutes in Morristown. The platform’s streaming updates provide a broader outlook, helping you plan weekend events in Sevierville or Chattanooga. The return of showers keeps the summer active, but the app’s precision ensures your plans stay flexible and safe.

Early June Outlook: Warm and Active
Early June maintains a warm, active pattern, with highs in the low to mid-80s and lows in the 60s, accompanied by occasional afternoon showers or storms typical of summer. Dew points in the mid-60s will keep humidity elevated, but sunny days will dominate, offering ample opportunities for outdoor fun. The EastTNweather platform’s long-range forecasts will refine this outlook, with the app’s alerts ensuring you stay ahead of any storms. This warm, vibrant weather is ideal for exploring Jonesborough’s historic charm, hiking in Sevierville, or enjoying community events in Morristown.

The platform’s streaming updates on YouTube and Roku provide context for the summer forecast, helping you plan commutes in Chattanooga or outdoor activities in the Smoky Mountains. The low to mid-80s and sunny stretches offer a perfect summer vibe, with the app’s precision keeping your plans on track. Whether visiting the Tennessee Riverpark or attending festivals in Knoxville, use the app to seize sunny days and prepare for occasional showers, ensuring a smooth and energetic start to June.
