   Areas affected...portions of southeastern Wyoming into northeastern
   Colorado and western Nebraska Panhandle

   Concerning...Tornado Watch 389...

   Valid 250047Z - 250145Z

   The severe weather threat for Tornado Watch 389 continues.

   SUMMARY...Severe hail and wind remain a concern with the more robust
   storms across portions of the central High Plains. An isolated
   tornado risk will also continue for at least a few more hours.

   DISCUSSION...Multiple supercells have oscillated in intensity across
   portions of southeastern WY into northeastern CO and western NE
   Panhandle, some of which have produced severe hail/gusts.
   Furthermore, at least one brief tornado reported in northeastern CO
   over the past hour. These storms are benefiting from a favorable
   kinematic and thermodynamic ambient environment, characterized by
   2500-3500 J/kg MLCAPE and up to 60 kts of effective bulk shear per
   00Z mesoanalysis. Storms closest to an effective baroclinic boundary
   also have the advantage of ingesting locally higher effective SRH,
   ranging from 200-500 m2/s2. The current thinking is that storms will
   continue to pulse in intensity through the remainder of daylight
   hours, producing severe wind and hail at their peak moments of
   intensity/organization. Additionally, isolated tornadoes will remain
   possible with mature supercells within the baroclinic zone.
