   Areas affected...Eastern/northeastern Mississippi and far western
   Alabama.

   Concerning...Tornado Watch 77...80...

   Valid 302259Z - 310030Z

   The severe weather threat for Tornado Watch 77, 80 continues.

   SUMMARY...The damaging wind and tornado threat continues from a line
   of storms with embedded supercells.

   DISCUSSION...The nature of the line has changed a bit over the past
   1 to 2 hours with a less cohesive QLCS and a more embedded cellular
   structure. Each of the tornado warnings and more sustained low-level
   circulations are associated with taller cores and reflectivity
   structures resembling embedded supercells. This change in nature of
   the line and a favorable low-level shear environment (0-1 km SRH in
   excess of 300 m2/s2 per KGWX VWP) may lead to an increase in tornado
   productivity for the next hour or two. Dewpoints are lower across
   Alabama, but some low-level moisture increase is expected, and the
   environment remains favorable for tornadoes through the evening and
   into the overnight hours.
