   The severe weather threat for Tornado Watch 50 continues.

   SUMMARY...Storms are expected to intensify throughout the afternoon,
   with several tornadic supercells possible including the threat of
   strong tornadoes.

   DISCUSSION...Areal coverage of thunderstorms has increased over the
   past 2 hours across central and into eastern MS, where a very moist
   and unstable air mass exists. Low-level winds have veered in the
   wake of the warm advection storms to the northeast, which has
   temporarily reduced SRH and made for straight hodographs. Indeed, a
   few storms have become left movers recently with hail threat.

   However, SRH will increase again over the next several hours as the
   surface low develops to the northwest. This should result in an SRH
   gradient over eastern MS and favorable parameters space for strong

   Current thinking is a few cells may consolidate into supercells out

   aloft will bring all storms into an environment favorable for
