   The severe weather threat for Severe Thunderstorm Watch 298

   SUMMARY...Local severe risk continues with clusters of storms moving
   east-southeastward toward/across the Arklatex region and
   southeastern Oklahoma.  New/downstream WW may be required soon.

   DISCUSSION...Latest radar loop shows two distinct clusters of
   strong/potentially severe storms -- one across southeastern
   Oklahoma, and the other moving across far southeastern Oklahoma and
   northeastern Texas, and moving into southwestern Arkansas.  This
   convection remains fairly well-organized, aided by persistent
   low-level warm advection within a thermodynamic environment
   featuring 2000 to 3000 J/kg mixed-layer CAPE, per recent RAP-based
   objective analysis.  

   Given ample instability downstream from the ongoing storms, and per
   CAM output, it seems that storms will likely continue moving
   east-southeastward over the next few hours -- with the leading
   cluster to begin exiting the existing WW over the next hour.  As
   such, new/downstream WW issuance may be needed.
