   Areas affected...portions of eastern Colorado into far northwestern
   Kansas and southwestern Nebraska

   Concerning...Tornado Watch 288...

   Valid 082314Z - 090045Z

   The severe weather threat for Tornado Watch 288 continues.

   SUMMARY...Severe threat continues within WW288. A corridor of better
   tornado potential may evolve over the next couple of hours in
   northeastern Colorado.

   DISCUSSION...Supercells continue to move east of the Denver metro
   this evening. These have produced many instances of large hail
   around 1-1.5 inches in diameter. Recent radar analysis shows an
   increase in low level rotation as these storms track eastward. These
   supercells are entering a zone of better low level moisture with dew
   points in the mid 50s to 60s F. Within this zone, backed easterly
   upslope flow will promote better low level curvature and streamwise
   vorticity, locally enhancing the tornado potential while discrete
   supercells remain. Eventually, clustering and upscale growth will
   favor a transition to a greater damaging wind threat.
