   Concerning...Severe Thunderstorm Watch 586...

   Valid 160713Z - 160845Z

   The severe weather threat for Severe Thunderstorm Watch 586
   continues.

   SUMMARY...Thunderstorms continue to move southeast out of eastern
   Wyoming and into/across portions of the Nebraska Panhandle. The
   threat for hail and gusty winds will continue for another couple of
   hours.

   DISCUSSION...Thunderstorms continue to move southeast from eastern
   Wyoming into and across the Nebraska Panhandle. These thunderstorms
   are slightly offset to the east-northeast from the best corridor of
   instability, being supported by warm-air advection originating
   within the corridor of better moisture and instability. The airmass
   feeding these thunderstorms has resulted in most-unstable CAPE
   values around 1000 J/kg and deep-layer shear around 50-60 knots.
   Given the organized nature of the ongoing thunderstorms, the
   potential for severe hail and gusty winds will continue for the next
   few hours before instability diminishes sufficiently -- and
   inhibition increases sufficiently -- to weaken overall thunderstorm
   intensity.
