   Areas affected...Parts of the Texas South Plains into Big Country of
   western north Texas

   Concerning...Severe Thunderstorm Watch 245...

   Valid 080611Z - 080815Z

   The severe weather threat for Severe Thunderstorm Watch 245
   continues.

   SUMMARY...Strong wind gusts remain possible with a southeastward
   advancing cluster of thunderstorms into the 3-5 AM time frame. 
   There remains potential for some re-intensification of storms,
   particularly with activity approaching the Abilene area during the
   next few hours.

   DISCUSSION...There has been some recent weakening (evident in MRMS
   CAPPI data) of the more intense convection on the leading edge of
   the southeastward propagating cold pool (still including 2-4+ mb 2
   hourly surface pressure rises in 05Z surface obs).  However, based
   on current 30 kt forward propagation, 10-20 south to southeasterly
   ambient near surface winds are contributing to strong inflow of
   seasonably high boundary-layer moisture content characterized by
   CAPE in excess of 3000 J/kg.  This extends along a corridor where
   stronger daytime differential surface heating took place, near the
   edge of warmer and more strongly capping elevated mixed-layer air
   across the higher plains, as far east-southeast as the Mineral Wells
   and Stephenville areas.  Although mid-level inhibition may be
   increasing, associated with continued gradual boundary-layer
   cooling, there still appears lingering potential for renewed storm
   intensification into the 08-10Z time frame.  As the modest southerly
   low-level over the Texas South Plains gradually veers, this may
   become focused near/above the southern flank of the cold pool and
   approach the Abilene vicinity.
