   Areas affected...Northwest OK...eastern OK panhandle...far northeast
   TX panhandle...and far southern Kansas

   Concerning...Severe Thunderstorm Watch 171...

   Valid 080224Z - 080400Z

   The severe weather threat for Severe Thunderstorm Watch 171
   continues.

   SUMMARY...Large to isolated very large hail expected for the next 1
   to 2 hours.

   DISCUSSION...Storm coverage has increased significantly in the last
   15 minutes along and ahead of a cold front moving into northwest
   Oklahoma. Expect storm coverage to continue to increase over the
   next 1 to 2 hours as the low-level jet strengthens across the area
   and moisture continues to advect northward. The primary threat will
   be large hail (some very large) in the next 2 hours given around
   2000 J/kg of MUCAPE per SPC mesoanalysis, mid-level lapse rates
   around 9 C/km per area 00Z RAOBs, and effective shear around 60
   knots supporting supercellular storm mode. 

   The extensive storm coverage will likely lead to significant storm
   interference and cold pool development by 04Z at which time the
   primary threat will likely start to transition to damaging winds.
