Concerning...Severe Thunderstorm Watch 298...

Valid 240751Z - 240945Z

The severe weather threat for Severe Thunderstorm Watch 298
continues.

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.
