   Areas affected...the Tennessee Valley Vicinity

   Concerning...Severe Thunderstorm Watch 238...239...240...

   Valid 082043Z - 082215Z

   The severe weather threat for Severe Thunderstorm Watch 238, 239,
   240 continues.

   SUMMARY...The ongoing large hail/damaging wind threat will continue
   through the late afternoon and into the evening.

   DISCUSSION...A broad region of moderate instability and moderate
   shear is present from central Kentucky southward into northeast
   Mississippi to the Appalachians. Within this area, multiple
   supercells have developed with reports of 1 to 2 inch hail. The
   environment across the region remains favorable through the
   remainder of the afternoon and into the evening. Therefore, ongoing
   supercells will likely continue with additional development also
   possible. The threat has been mostly hail thus far given the more
   discrete mode. However, as storms coverage increases, expect
   clusters and potential bowing line segments to develop. This would
   result in a greater damaging wind threat this evening.
