Strong to severe storms will be possible across the eastern Tennessee Valley this evening and overnight. The main threats with these storms will be damaging winds, hail, and locally heavy rainfall. However, an isolated tornado cannot be ruled out, mainly along the southern Cumberland Plateau and southeast Tennessee. An additional round of strong to marginally severe thunderstorms is possible sunday afternoon. Locally heavy rainfall over the weekend and into early next week may cause some localized flooding issues, as 2 to 3 inches of rainfall is expected, with locally higher amounts along the mountain possible.
