A strong low pressure system will pull deep sub-tropical moisture into the Tennessee Valley and Southern Appalachians Sunday night. At the same time, a slow moving cold front will move into the area from the southwest. This frontal boundary will combine with the abundant moisture to produce a long duration rain event early next week. Some of the rain will be moderate to heavy with rainfall amounts of 2 to 3 inches anticipated, with locally heavier amounts possible along the east Tennessee and western North Carolina mountains. Localized runoff problems and areal flooding of poor drainage areas are possible. Flash flooding of low lying areas, roadway flooding and rapid stream rise are also possible in areas that repeatedly experience heavy showers and thunderstorms over a short period of time. Stay alert for possible flood watches and warnings and know what to do if a warning is issued.
Given the potential for locally heavy rainfall late this weekend into early next week, make sure you know your flood safety rules and know what to do if a warning is issue. One of the biggest rules: do NOT drive across flooded roadways! Turn Around, Don't Drown!
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.
