   Areas affected...Western Oklahoma and much of the Texas Panhandle

   Concerning...Severe Thunderstorm Watch 333...

   Valid 152245Z - 152345Z

   The severe weather threat for Severe Thunderstorm Watch 333

   SUMMARY...The severe threat continues across WW 333.

   DISCUSSION...Isolated-to-scattered convective activity has evolved
   across WW 333 ahead of a dryline located from near DDC in
   southwestern Kansas to AMA to HOB in southeastern New Mexico.  A
   strongly unstable pre-convective airmass - supported by very steep
   tropospheric lapse rates, 60s to low 70s dewpoints, and 90s F
   surface temperatures - is supporting a risk of large hail (perhaps
   significant) and damaging wind gusts with this activity.  Enough
   deep shear exists for some storm organization (including occasional
   supercell structures) although weaknesses in the low- and mid-level
   kinematic fields are supporting mostly outflow dominant storms. 
   Some southeastward propagation of these storms is observed via radar
   and satellite observations.  The outflow-dominant nature of these
   storms may allow for localized linear segments to develop as these
   storms propagate southeastward over the next 1-2 hours, perhaps
   enhancing the existing damaging wind potential with this activity.
