   Areas affected...southern Arkansas...far northern Louisiana...and
   into northern and western Mississippi

   Concerning...Tornado Watch 36...38...

   Valid 150439Z - 150615Z

   The severe weather threat for Tornado Watch 36, 38 continues.

   SUMMARY...Tornado risk is evolving across portions of southern
   Arkansas, far northern Louisiana, and western Mississippi.

   DISCUSSION...Latest radar loop shows a band of supercells moving
   eastward across Arkansas at this time, several with ongoing/strong
   circulations evident.  The southern portion of this band -- over
   southern Arkansas -- will continue moving eastward across
   northwestern portions of Tornado Watch 38.  Meanwhile farther east,
   a supercell is crossing southern Leflore County in west-central
   Mississippi, which is also exhibiting low-level rotation. 

   Meanwhile, other/weaker convection is evolving south of this storm,
   where CAMs suggest potential for an increase in severe-storm
   potential over the next couple of hours.  Given the favorable
   environment (both kinematically and thermodynamically), expect risk
   to continue across portions of WW 38 for several hours across this
   region.
