A disturbance will be in the area tomorrow, creating the potential for heavy rains. The GFS model is printing upwards of 2 inches of rain in a 24 hour period from tonight to tomorrow evening, with the heaviest rains centered over southeast Tennessee. Such heavy rains in such a short amount of time create a problematic scenario where flooding can arise very quickly, depending on how fast the rain falls. My concern is that some areas in Mississippi and even parts of Louisiana may get some un-needed rain, after a drenching last several days. Luckily, rivers are not agitated in east Tennessee and nearby areas, so any flash flooding is likely to be relatively minor and non life-threatening.
