   Areas affected...eastern Wyoming/eastern Colorado into the Nebraska
   Panhandle

   Concerning...Severe Thunderstorm Watch 570...

   Valid 112251Z - 120045Z

   The severe weather threat for Severe Thunderstorm Watch 570
   continues.

   SUMMARY...Strong/locally severe thunderstorms continue across WW
   570.

   DISCUSSION...Latest radar loop shows widespread thunderstorms --
   including a few well-organized, rotating updrafts -- occurring over
   the central high Plains region.  The storms are evolving near
   multiple/complex boundary interactions across the area.  With
   low-level east-southeast flow advecting moist low-level air (60s
   dewpoints) into the high Plains fueling the convection, expect
   storms to continue for several hours.

   A couple of brief tornadoes have been reported over the past couple
   of hours, and large hail is also indicated with a couple of the most
   intense updrafts.  These risks -- along with potential for locally
   damaging wind gusts -- are ongoing.  With time, storms should grow
   upscale, and spread eastward into/across southwestern Nebraska and
   northwestern Kansas -- where Tornado Watch 572 is currently in
   effect.
