   Areas affected...Western and Middle Tennessee

   Concerning...Severe Thunderstorm Watch 603...

   Valid 201026Z - 201130Z

   The severe weather threat for Severe Thunderstorm Watch 603
   continues.

   SUMMARY...Severe Thunderstorm Watch 603 will expire at 11z, and a
   new watch is not expected.

   DISCUSSION...Widespread thunderstorms and stratiform precipitation
   continue across portions of western and Middle Tennessee at 1020z.
   Substantial convective overturning and weakening low-level warm
   advection have led to generally diminished intensities over most of
   the remaining watch area since 09z. Although an occasionally
   stronger storm will remain possible over the next 1-2 hours over
   western and Middle TN in proximity to a modestly veering low-level
   jet, current and expected short-term convective trends should
   preclude the need for a new watch.
