   Areas affected...central and northern Mississippi...parts of
   southwest Tennessee...northwest Alabama

   Concerning...Severe potential...Tornado Watch likely 

   Valid 251558Z - 251830Z

   Probability of Watch Issuance...95 percent

   SUMMARY...Storms are expected to form over the next couple hours
   over central and western Mississippi. Supercells are likely, with
   tornado threat increasing as cells mature and move northeast toward
   Alabama. Watch will be issues soon.

   DISCUSSION...Visible imagery and surface obs indicate the air mass
   continues to destabilize with areas of heating, as temperatures rise
   into the mid 70s F over the warm sector. This is sufficiently warm
   for surface-based parcels. Indications are that cells may develop
   both ahead of the cold front due to a very moist warm sector, and
   along the front itself. Deep-layer shear is expected to strengthen
   storms, which will gain intensity and tornado potential as they
   mature and continue northeastward across MS and into AL. The threat
   may extend into southern TN as well, once the warm front lifts
   there.
