   Areas affected...southeast Louisiana through southern Mississippi

   Concerning...Tornado Watch 26...

   Valid 071856Z - 072000Z

   The severe weather threat for Tornado Watch 26 continues.

   SUMMARY...Tornado watch 26 is scheduled to expire at 20Z. However,
   storms will probably not have cleared the southeast portion of the
   WW by that time. A local 2 hour extension in time may be necessary
   for that portion of the WW to cover remaining threat.

   DISCUSSION...Several discrete supercells persist over southeast LA
   into the MS bootheel and are moving east at around 30 kt. While the
   atmosphere upstream remains quite unstable, winds are veering and
   subsidence drying aloft in wake of shortwave trough will likely
   limit additional development west of ongoing storms. This suggests
   the primary tornado threat should remain confined to a small area
   across southeast LA into southeast MS next few hours before storms
   move into WW 27. Farther north across south central to central MS
   where the boundary layer is less unstable, primary threat appears to
   be damaging wind and large hail, but a tornado or two cannot be
   ruled out.
