   Areas affected...central and southern MS into portions of southern
   LA

   Concerning...Tornado Watch 585...586...

   Valid 140813Z - 141015Z

   The severe weather threat for Tornado Watch 585, 586 continues.

   SUMMARY...A couple of tornadoes and sporadic strong gusts remain
   possible across WW 585 and 586. The greatest relative threat into
   early morning will exist across southern MS into southwest LA.

   DISCUSSION...A surface warm front is analyzed from near
   Holmes/Attala counties in MS southeastward toward the Mobile Bay
   vicinity as of 08z. This warm front is not expected to move much
   over the next several hours, which will confine the better
   warm-sector airmass across southern MS into southern LA through
   early morning. An ongoing line of convection with bowing segments
   and embedded supercells continues to very slowly shift eastward with
   some transition toward training convection and heavy rain over the
   past couple of hours. Semi-discrete cells appear most likely across
   parts of southern LA into far southern MS where low-level confluence
   is most apparent. Given favorable low-level shear and modest
   instability, rotating cells, both ahead of the line and embedded
   within the line, will continue to pose a risk for a couple of
   tornadoes and sporadic strong gusts into early morning across WW 585
   and 586. A new watch or local extension in time may be needed across
   parts of southwest LA as WW 585 is set to expire at 10z, and some
   threat may persist beyond watch expiration time.
