   Areas affected...from central Louisiana east into southern Alabama

   Concerning...Severe Thunderstorm Watch 225...226...

   Valid 100441Z - 100545Z

   The severe weather threat for Severe Thunderstorm Watch 225, 226

   SUMMARY...Clusters of strong/severe storms -- capable of producing
   damaging winds and hail -- will continue moving eastward across
   portions of WW 225 and 226.  New WW may be required to extend a bit
   farther south into parts of southeastern Louisiana.

   DISCUSSION...Widespread thunderstorms currently extend from
   east-central/southeastern Mississippi west-southwestward to
   southwestern Louisiana.  Meanwhile, a weakening band of storms is
   moving into southwestern Georgia -- but with new storm development
   over southern Alabama along remnant outflow.

   Overall, a very unstable (averaging 3000 J/kg mixed-layer CAPE)
   persists across the central Gulf Coast region south of areas that
   have been convectively overturned previously.  This suggests that
   storms should persist well into the overnight, spreading eastward
   out of Mississippi into Alabama, and perhaps expanding a bit
   southward into parts of southeastern Louisiana.  Locally damaging
   wind gusts and hail can be expected across this area, and a new WW
   south of the existing watches may be needed in the short term, to
   cover the southern extent of this risk area.
