   The severe weather threat for Severe Thunderstorm Watch 94
   continues.

   SUMMARY...Storms moving into northern MS/AL may pose an isolated
   large hail and damaging wind threat overnight. A downstream watch
   into parts of central MS/AL may be needed.

   DISCUSSION...A couple of storm clusters moving southeastward out of
   southern/middle TN into northern MS/AL have recently intensified.
   This may be due to a modestly strengthening 40-50 kt westerly
   low-level jet noted on recent KGWX VWPs. A reservoir of rich
   low-level moisture is present ahead of this convection, with surface
   dewpoints generally in the mid to upper 60s. One of the storms now
   moving into far northwestern AL embedded within a larger cluster is
   exhibiting supercellular characteristics. Strengthening westerly
   flow through mid levels is supporting around 50 kt of effective bulk
   shear. And, some modest steepening of mid-level lapse rates is still
   present across northern MS/AL. This suggests isolated large hail
   will remain possible with any supercells that can persist overnight.
   Otherwise, damaging winds should also be a threat with the cluster
   moving southeastward out of northeastern MS into northwestern and
   west-central AL. Depending on short term convective trends, a
   downstream watch into parts of northern/central MS and central AL
   may be needed in the next hour or so.
