Severe Storms, Flash Flooding Risks, and a Cooler Shift

Today: Severe Storms and Flash Flooding Risks
East Tennessee is bracing for another round of strong to severe storms today as a cold front moves into the region. The Storm Prediction Center has placed the area under a Level 1 (Marginal) risk, indicating a low but notable chance for severe weather. The primary threat is damaging wind gusts, which could reach 60-70 mph in the strongest storms, potentially causing downed trees and power outages, especially in areas like the Cumberland Plateau and Knoxville. Sub-severe hail is also a concern, with the freezing level at around 9,000 feet, meaning hailstones may be smaller but widespread, particularly in storms across the Smoky Mountains and Sevierville.

The most pressing concern is the risk of localized flooding and flash flooding, especially south of I-40, where areas like Chattanooga, Cleveland, and Athens have already received 2-4 inches of rainfall over the past two days. With an additional 1-2 inches expected through Sunday morning, saturated soils could lead to rapid runoff, flooding low-lying areas, and flash flooding in urban zones like Knoxville or valleys in the Smokies. The EastTNweather app is your go-to tool for tracking these storms and flood risks, offering real-time radar and alerts. Whether you’re hiking in Cades Cove, exploring Market Square, or commuting in Morristown, stay vigilant and avoid flooded roads, as just one foot of water can float a vehicle.

Recent Rainfall and flooding Concerns
The past 48 hours have brought significant rainfall to East Tennessee, with southern areas south of I-40 seeing 2-4 inches, saturating the ground and elevating flood risks. This heavy rainfall, combined with today’s expected 1-2 inches through Sunday morning, increases the likelihood of localized flooding in areas like Chattanooga, where urban drainage systems may struggle, and in the Smoky Mountains, where valleys are prone to rapid runoff. Flash flooding is a particular concern in low-lying areas and near streams, especially if storms “train” over the same locations, dropping heavy rain in short periods.

The EastTNweather platform, including the app and website (easttnweather.com), provides critical updates on flood watches and warnings issued by the National Weather Service. For residents in flood-prone areas, such as parts of Knoxville or Sevierville, stay alert for rapid water rises and follow local officials’ guidance. The platform’s streaming options on Roku, Amazon Fire, and YouTube make it easy to stay informed, whether you’re at home or on the go. If you’re planning outdoor activities, such as festivals in Pigeon Forge or hiking in the Smokies, have indoor backups ready, like the Knoxville Museum of Art or the East Tennessee History Center, to stay safe and dry.

Sunday through Tuesday: Cooler and Drier with an Upper-Level Low Hanging Around
An upper-level low will linger over East Tennessee through Tuesday, bringing a refreshing shift after the stormy start. Highs on Sunday and Monday will drop to the upper 60s, with dew points falling into the 40s, lowering humidity and creating a crisp, comfortable feel. Morning lows on Monday and Tuesday will dip into the 40s, offering chilly starts that may require a light jacket, especially in higher elevations like the Smoky Mountains or the Cumberland Plateau. A few scattered showers may persist through Tuesday, but they’ll be lighter and less widespread than the weekend’s storms.

This cooler, drier weather will be a welcome change, perfect for outdoor activities like strolling through Ijams Nature Center, visiting the Knoxville Zoo, or exploring the historic town of Jonesborough. The lower humidity will enhance visibility, offering stunning views of the Smoky Mountains and a vibrant backdrop for your plans. The EastTNweather app’s hourly forecasts will help you time your activities to avoid any stray showers, ensuring you make the most of this pleasant period. The cooler temperatures and chilly mornings reflect East Tennessee’s dynamic spring climate, where rapid shifts keep the region lively and engaging.

Wednesday through Friday: More Showers and Seasonal Temperatures
The weather turns active again midweek, with more rounds of showers and storms expected from Wednesday through Friday. Temperatures will rebound to seasonal averages in the mid-70s, bringing a return to typical spring warmth. While severe weather risks appear low at this time, the potential for heavy rain could renew flooding concerns, especially in areas still recovering from the weekend’s rainfall. The EastTNweather platform, led by Mike Witcher, will provide updates as the forecast evolves, ensuring you’re prepared for any shifts in storm intensity or timing.

The midweek showers make it a great time for indoor activities, such as visiting Dollywood’s indoor attractions or exploring the Knoxville Botanical Garden’s exhibits. For outdoor enthusiasts, plan morning or evening outings to minimize exposure to rain, and keep rain gear handy for sudden showers. The EastTNweather app’s interactive radar and customizable alerts are perfect for tracking these weather systems, whether you’re in Knoxville, Gatlinburg, or the Cumberland Plateau. The return to seasonal temperatures will keep East Tennessee vibrant, offering ample opportunities to enjoy the region’s natural and cultural attractions between rain showers.
