   Concerning...Severe Thunderstorm Watch 582...

   Valid 142358Z - 150130Z

   The severe weather threat for Severe Thunderstorm Watch 582
   continues.

   SUMMARY...Isolated strong to severe storms with large hail and
   downburst winds will persist through about 02Z, followed by a
   diminishing trend.

   DISCUSSION...New storms have recently developed near the
   CO/northwest KS border along what appears to be the merger between a
   northwest-southeast oriented boundary and a southwest advancing
   outflow boundary. It remains possible that other isolated storms may
   develop farther northwest over the higher terrain and spread
   southeast. Vertical wind profiles with 40-50 kt effective bulk shear
   support potential for some supercell structures. Activity is
   developing within an environment characterized by weak forcing aloft
   suggesting storms are mostly diurnally driven and should remain
   isolated. Convective inhibition will increase substantially with
   onset of nocturnal cooling, and storms are expected to begin a
   gradual weakening trend by 02Z.
