   Areas affected...Portions of northern AL...northern MS...and
   southeastern AR

   Concerning...Severe Thunderstorm Watch 401...402...

   Valid 100019Z - 100145Z

   The severe weather threat for Severe Thunderstorm Watch 401, 402
   continues.

   SUMMARY...The risk of isolated large hail and locally damaging gusts
   continues across parts of Severe Thunderstorm Watches 401 and 402.

   DISCUSSION...Isolated to widely scattered thunderstorms are ongoing
   from parts of southeastern AR eastward into northern AL -- generally
   focused along a sagging frontal boundary. While a warm/moist
   boundary layer and around 30-35 kt of unidirectional westerly
   deep-layer shear (per regional VWP) continue to support
   organized/transient supercell structures and small clusters, there
   has been a tendency for storms to be undercut by the
   southward-sagging boundary and outflow -- given the westerly storm
   motions and shear. This suggests that isolated large hail (up to 1.5
   inches) will be the primary threat with any organized/sustained
   storms, though locally damaging gusts are also possible.
