A strong low pressure system will pull deep sub-tropical moisture into the Tennessee Valley and Southern Appalachians tonight. 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 1.5 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!
A few strong to marginally severe thunderstorms are possible this afternoon and evening. Greatest threat lies in SW NC and SE TN. In addition, periods of moderate to heavy rainfall will move across the region this evening and overnight as an upper-low tracks across the Southern Appalachians. Some localized flooding issues, as 1.5 to 2.5 inches of rainfall with locally higher amounts in the mountains, are possible.
