   Areas affected...far southeast MS...southwest AL

   Concerning...Tornado Watch 588...

   Valid 150024Z - 150130Z

   The severe weather threat for Tornado Watch 588 continues.

   SUMMARY...A couple of tornadoes are possible over the next hour or
   so across southwest AL.

   DISCUSSION...KMOB radar imagery over the past 1-2 hours has shown an
   evolution from a embedded supercell-squall line morphology, to the
   convective line growing downscale into quasi-discrete supercells
   embedded within a rain shield across the southeast MS into southwest
   AL.  This appears to be partly related to the approach of a
   negatively tilted shortwave trough moving northeast across the lower
   MS Valley early this evening and its influence on modifying the wind
   profile.  

   The airmass across southwest AL is very moist with dewpoints in the
   upper 60s to 70 deg F to the south of a maritime warm front.  RAP
   forecast soundings show 0-0.5 km SRH around 300-350 m2/s2 and MLCAPE
   ranging from 750 J/kg near the warm front to 1500 J/kg farther south
   near Mobile.  The enlarged hodographs will support intermittently
   strong low-level mesocyclones and a tornado threat.
