   Areas affected...Portions of middle/eastern Tennessee and Kentucky

   Concerning...Severe Thunderstorm Watch 293...

   Valid 232341Z - 240115Z

   The severe weather threat for Severe Thunderstorm Watch 293
   continues.

   SUMMARY...A locally damaging wind and marginally severe hail threat
   will continue for another 1 to 2 hours across portions middle and
   eastern TN, and KY.

   DISCUSSION...A cluster of thunderstorms associated with an MCV,
   along with an embedded bowing segment now moving into Campbell
   County, will continue to pose a severe damaging wind threat over the
   next couple of hours. After-which, the system will begin to move
   into a less favorable thermodynamic environment downstream. In
   addition to damaging winds, any of the more discrete updrafts within
   30-35 kt of deep effective layer shear could become briefly
   organized and produce marginally severe hail up to 1.25" in
   diameter. However, poor mid-level lapse rates should keep this
   threat fairly isolated. A watch extension east of the cluster may be
   necessary.
