   Areas affected...Parts of southern LA...southern MS...and far
   southwestern AL

   Concerning...Tornado Watch 6...

   Valid 150443Z - 150645Z

   The severe weather threat for Tornado Watch 6 continues.

   SUMMARY...A heightened tornado risk is evident over parts of
   southern Louisiana into southwestern Mississippi in the near term --
   within Tornado Watch #6. A downstream tornado watch will be issued
   within an hour.

   DISCUSSION...A squall line with embedded mesovorticies and supercell
   structures is tracking eastward across southern LA and southwestern
   MS tonight. The line is impinging on a corridor of middle/upper 60s
   dewpoints, which is yielding weakly unstable inflow for these
   storms. However, the low-level mass response accompanying an
   approaching midlevel trough continues to favor a 40-50 kt low-level
   jet and ample low-level hodograph curvature (around 350-400 m2/s2
   0-1 km SRH per regional VWP). Given the well-established line of
   storms and this enhanced low-level helicity, a corridor of
   heightened tornado potential is evident across parts of southern LA
   into southwestern MS in the near term, and a strong tornado cannot
   be entirely ruled out. 

   Thereafter, the squall line will continue eastward along a
   progressive cold front moving across southeastern LA, southern MS,
   and far southwestern AL -- where sufficient boundary-layer moisture
   and strong low/deep-layer shear will support a continued risk of
   damaging wind gusts and a couple tornadoes. A downstream tornado
   watch will be issued within an hour for this threat.
