   Areas affected...far southeast LA...coastal MS

   Concerning...Tornado Watch 588...

   Valid 142235Z - 150030Z

   The severe weather threat for Tornado Watch 588 continues.

   SUMMARY...The supercell tornado risk will be greatest from far
   southeast LA northeastward to the coastal counties of MS through
   630pm CST.  The potential for a strong tornado will probably be
   highest with any discrete supercell ahead of the convective line.

   DISCUSSION...Radar mosaic shows a broken line of storms with
   embedded supercells from southeast MS southwestward through the New
   Orleans metro and into coastal southeast LA.  A couple of discrete
   supercells have developed ahead of the convective line over
   southeast LA.  These storms will likely have the greatest window of
   opportunity for longevity in the warm sector over the next couple of
   hours.  The latest RAP forecast soundings show a gradual
   strengthening of low-level flow and enlargement of the hodograph
   over coastal MS and AL through 6pm CST.  This trend in the
   strengthening wind profile has been observed from the KMOB VAD
   during the past 2 hours.  

   Given the moist/buoyant airmass in place over the immediate central
   Gulf Coast, the potential will exist for a few supercells capable of
   a tornado risk through the early evening.  The tornado risk will
   likely focus with the discrete supercells, but some threat for a
   tornado and damaging gusts will continue with storms embedded within
   the line as this activity slowly pushes eastward over the next
   couple of hours.
