Happy Wednesday, East Tennessee!
On this May 21, 2025, at 7:22 AM EDT, we’re breathing a sigh of relief as the calm after last night’s wild severe storms settles in, bringing cool, comfortable weather through Saturday. After a night of severe thunderstorms and tornado warnings, I thank you for trusting theEastTNweather platform, led by meteorologist Mike Witcher, to keep you safe and informed. Your support makes it all worthwhile! From the vibrant streets of Knoxville to the serene Great Smoky Mountains and the rugged Cumberland Plateau, today’s breezy, dry air precedes a pleasant stretch, but heavy rain looms for Memorial Day weekend.
After last night’s intense severe weather, Wednesday dawns with morning fog and low clouds across East Tennessee, with temperatures starting in the 60s and dew points in the 50s to low 60s. Cooler, drier air moves in behind the cold front, kicking up breezy conditions with gusts up to 25 mph through the afternoon. Highs will reach the upper 70s to low 80s, near average, but falling dew points in the low 50s create a comfortable evening with temperatures dropping to the upper 60s to low 70s. This refreshing air is a welcome shift from yesterday’s muggy, storm-fueled heat.
TheEastTNweather appis your go-to for tracking fog and wind, offering real-time updates to navigate the morning commute in Knoxville or Morristown. The breezy day is perfect for outdoor activities like picnics at Knoxville’s World’s Fair Park or short hikes in the Smoky Mountains, with the app’s hyper-local forecasts ensuring you stay comfortable. Tonight, a weak wave brings increased clouds and a chance for light rain, primarily overnight, but it should clear by Thursday’s morning commute. Secure lightweight outdoor items due to gusts, and use the app to monitor any light rain, especially in Chattanooga or the Cumberland Plateau.
Thursday: Cool, Crisp, and Mostly Dry
Thursday brings a mix of sun and clouds with cooler highs in the low 70s, as dew points drop into the 40s, creating a fantastic, crisp feel. A slight chance for a few passing afternoon showers exists, particularly south of I-40 in areas like Chattanooga or Cleveland, but Mike Witcher expects minimal impact. The dry, comfortable air makes it an ideal day for outdoor adventures, from visiting the Knoxville Zoo to exploring Gatlinburg’s scenic trails or kayaking on the Tennessee River.
Friday and Saturday: Pleasant Spring Weather
Friday and Saturday continue the pleasant trend, with highs in the upper 60s to low 70s and lows in the 50s. The dry air and low dew points in the 40s maintain a comfortable, spring-like feel, ideal for outdoor activities across East Tennessee. Friday’s clear skies are perfect for hiking in the Cumberland Plateau or visiting Chattanooga’s riverfront, while Saturday’s partly cloudy conditions favor festivals in Sevierville or picnics in Knoxville’s Tyson Park.
The EastTNweather app’s hourly forecasts ensure you maximize these delightful days, with streaming updates providing a broader outlook. The dry, mild weather is a springtime gift, offering a stark contrast to last night’s storms and the upcoming Memorial Day weekend rain. Plan outdoor events with confidence, but keep the app handy for any unexpected shifts, especially in the Smoky Mountains or Morristown, where morning lows may feel chilly. This pleasant stretch sets the stage for a relaxing pre-holiday weekend before the weather turns active again.
Memorial Day Weekend: Heavy Rain Returns
The calm weather shifts dramatically by Sunday, as dew points climb back to the upper 60s, fueling showers and storms through Tuesday. An area of low pressure traversing Tennessee will bring heavy rain, with 1-2 inches possible, heaviest south of I-40 in Chattanooga, Cleveland, and Athens. Sunday’s storms may start in the afternoon, continuing into Monday and Tuesday, with potential for gusty winds or localized flooding in areas saturated by recent rains. Highs will drop to the low to mid-70s, with muggy conditions returning.
The EastTNweather platform’s long-range forecasts will track this system, with the app’s alerts ensuring you stay ahead of heavy rain. Indoor backups, like the East Tennessee History Center or the Tennessee Aquarium, are essential for Memorial Day plans, especially in southern areas. The platform’s streaming updates on YouTube and Roku will refine the holiday forecast, helping you time outdoor barbecues in Knoxville or Smoky Mountain hikes around showers. Check the app’s radar for dry windows, particularly north of I-40, where rain may be less intense. The wet holiday weekend underscores East Tennessee’s dynamic spring climate.
