   Areas affected...western and middle Tennessee...northwestern Alabama

   Concerning...Severe Thunderstorm Watch 80...

   Valid 100020Z - 100215Z

   The severe weather threat for Severe Thunderstorm Watch 80
   continues.

   SUMMARY...Storms producing hail persist from northeast Mississippi
   into western Tennessee, and may extend east of WW 80 from northwest
   Alabama into western Middle Tennessee. It is unclear whether an
   additional watch will be needed.

   DISCUSSION...A north-south line of cells likely producing hail
   currently extend from Pontotoc County MS to Chester County TN. These
   storms are located near the northeastern extend of the better
   instability, with MLCAPE up to 1500 J/kg into southwestern TN.

   Modest low-level moist advection may support these storms for a
   couple hours as the line drifts eastward into northwest AL and
   middle TN. The most likely area for a prolonged hail threat is from
   northeast MS into northwest AL, in closer proximity to the mid 60s F
   dewpoints. Other storms approaching Middle Tennessee are more likely
   to weaken as they encounter drier air and the boundary layer cools
   further.
