   Areas affected...Southwest/southern middle TN into northern AL and
   far northeast MS

   Concerning...Severe Thunderstorm Watch 517...

   Valid 270406Z - 270530Z

   The severe weather threat for Severe Thunderstorm Watch 517
   continues.

   SUMMARY...Isolated damaging wind will remain possible into the early
   morning hours.

   DISCUSSION...A long-lived storm cluster continues to move southward
   across parts of western/middle TN late this evening. Some weakening
   has been noted over the last 1-2 hours, and a gradual weakening
   trend is expected to continue, due to weak low-level flow and weaker
   deep-layer flow/shear with southward extent. However, very rich
   low-level moisture continues to support strong to extreme buoyancy,
   with downstream MLCAPE in the 3000-4000 J/kg range. This buoyancy
   may aid in occasional updraft intensification along the gust front,
   and a continuation of at least an isolated damaging-wind threat into
   the early overnight hours across northern AL and far northeast MS.
