   Areas affected...Parts of southeast KY into northeast TN

   Concerning...Severe Thunderstorm Watch 523...

   Valid 280414Z - 280545Z

   The severe weather threat for Severe Thunderstorm Watch 523
   continues.

   SUMMARY...A localized damaging-wind threat may continue into the
   early morning hours.

   DISCUSSION...A small storm cluster with an earlier history of
   producing wind damage is approaching northeast TN from southeast KY
   as of 0410 UTC. While some nocturnal cooling has occurred, the
   downstream environment remains somewhat favorable for maintaining
   deep convection, with rich moisture, moderate buoyancy, and around
   30-40 kt of effective shear. As a result, a localized wind-damage
   threat may eventually spread out of WW 523, though a general
   weakening trend is expected to continue with time overnight.
