   Areas affected...Portions of southern LA and coastal MS

   Concerning...Tornado Watch 94...

   Valid 051530Z - 051630Z

   The severe weather threat for Tornado Watch 94 continues.

   SUMMARY...An isolated severe threat may persist across parts of
   southern Louisiana and coastal Mississippi in the short term, but
   the overall severe threat should gradually decrease this afternoon.

   DISCUSSION...The trailing portion of a convective line has become
   increasingly oriented east-west across parts of southern LA and
   coastal MS. Recent VWPs from KLIX show gradually veering low-level
   winds, but strong speed shear is still present in the boundary
   layer. An isolated threat for mainly strong/gusty winds could
   persist beyond the scheduled 16Z expiration time of Tornado Watch
   94, and a local extension in time remains possible. But, the overall
   severe threat should gradually decrease across this region through
   the early afternoon as better large-scale ascent associated with a
   shortwave trough over the Southeast and stronger low/mid-level flow
   shift eastward and away from this area.
