Happy Saturday, East Tennessee!
On this May 31, 2025, we’re celebrating the last day of May with a vibrant mix of patchy fog, plenty of sunshine, and a chance for late-day storms as a cold front approaches. From the bustling streets of Knoxville to the serene trails of the Great Smoky Mountains and the rugged Cumberland Plateau, today’s weather sets the stage for a dynamic weekend and a hot start to June. TheEastTNweather platform, led by meteorologist Mike Witcher, delivers hyper-local updates via its app, website, YouTube, Roku, Amazon Fire, and Apple TV to keep you prepared.
Saturday: A Foggy & Sunny Start with Late Day Storms
Saturday kicks off with patchy dense fog in low-lying areas, particularly along the Cumberland Plateau and in valleys near Chattanooga and the Smoky Mountains. Morning temperatures start comfortably in the 50s, thanks to slightly drier air, under clear skies and abundant sunshine. As a cold front dips in from the north, clouds will increase through the day, setting the stage for showers and storms, likely after 3 PM and closer to sundown (around 8:30 PM EDT). These storms could bring gusty winds and small hail, especially north of I-40 in Knoxville, Morristown, and Upper East Tennessee. Highs will reach the mid to upper 70s and low 80s, near the seasonal average of 81°F, with dew points in the low 60s keeping conditions comfortable but warm.
TheEastTNweather appis your go-to for tracking these storms, with its Interactive Radar offering past, current, and two-hour future projections to plan outdoor activities. Plan morning hikes in Cades Cove, picnics at Knoxville’s Tyson Park, or festivals in Pigeon Forge, but keep an eye on the app for afternoon storm updates. South of I-40, including Chattanooga and Cleveland, expect fewer storms and more sunshine, ideal for riverfront strolls or outdoor dining. The app’s hyper-local forecasts and alerts ensure you can dodge late-day storms, making Saturday perfect for enjoying the sunshine before the rain arrives. Secure outdoor items for potential gusty winds, and make it a great last day of May!
Sunday: Showers and Storms in the Afternoon
Sunday brings another round of active weather as an upper-level wave moves through during the early afternoon hours, sparking showers and storms across East Tennessee. Highs will reach the upper 70s to low 80s, with muggy dew points in the mid-60s fueling storm development. Storms could produce hail (up to 0.75 inches) and gusty winds (up to 50 mph), with the greatest risk south of I-40 in Chattanooga, Cleveland, and Athens. North of I-40, including Knoxville and the Smoky Mountains, expect scattered showers and storms with less intensity. Rainfall amounts will range from 0.25-0.75 inches, heaviest in southern areas, but no widespread flooding is anticipated.
The EastTNweather platform’s streaming updates on YouTube, Roku, Amazon Fire, and Apple TV, led by Mike Witcher, provide context for Sunday’s stormy forecast, while the app’s Interactive Radar tracks shower timing. Plan morning activities like visiting the Knoxville Zoo or exploring Gatlinburg’s trails, with indoor backups like the Tennessee Aquarium or East Tennessee History Center ready for afternoon storms. South of I-40, use the app to monitor stronger storms, and avoid outdoor plans during peak storm hours (1-5 PM). North of I-40, seize dry windows for short hikes or Morristown outings, with the app’s alerts keeping you safe. Sunday’s storms won’t ruin the day but require flexibility to stay vibrant.
Next Week: June Heat Takes Hold
As we dive into the first week of June, a ridge of high pressure builds in, bringing summer-like heat and mostly dry conditions. Highs will climb into the mid to upper 80s, with heat index values in the low 90s due to dew points in the mid to upper 60s, making it feel sticky and warm. Monday through Wednesday offer mostly sunny skies, perfect for outdoor activities like kayaking on the Tennessee River, visiting the Knoxville Botanical Garden, or attending concerts in Chattanooga. However, another storm system approaches Thursday and Friday, bringing a chance for showers and storms, with rainfall amounts of 0.5-1 inch possible, heaviest south of I-40.
The EastTNweather app’s long-range forecasts ensure you maximize the sunny, hot days, with streaming updates on YouTube and Roku providing context for the June heat. Plan outdoor events in Pigeon Forge or hikes in the Cumberland Plateau for Monday-Wednesday, but stay hydrated and apply sunscreen in the mid to upper 80s. Use the app’s radar to track Thursday-Friday storms, especially in Chattanooga or Cleveland, and have indoor options like the Knoxville Museum of Art ready. The app’s alerts keep you prepared for the week’s end, ensuring your summer plans stay on track. The June heat marks a vibrant start to the season, with a touch of stormy excitement.
Early June Outlook: Warm and Active
The warm, active pattern continues into early June, with highs in the low to mid-80s and occasional afternoon showers or storms typical of summer. Dew points in the mid-60s will keep humidity elevated, but dry days will outnumber wet ones, offering ample opportunities for outdoor fun. The EastTNweather platform’s forecasts will refine this outlook, with the app’s alerts ensuring you stay ahead of any storms. This stable, warm weather is ideal for exploring Jonesborough’s historic charm, hiking in Sevierville, or enjoying Morristown’s community events.
The platform’s streaming updates provide a broader perspective, 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 kickoff, with the app’s precision keeping your plans vibrant. 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 start to June’s warmth and energy.
