   Areas affected...far northeastern CO...NE Panhandle

   Concerning...Severe potential...Watch unlikely 

   Valid 100205Z - 100300Z

   Probability of Watch Issuance...20 percent

   SUMMARY...The threat for isolated large hail will probably continue
   for the next 1-2 hours before nocturnal stabilization occurs this
   evening and storms subsequently weaken.

   DISCUSSION...Radar mosaic indicates several supercells across the
   central High Plains from far northeastern CO northward into western
   NE.  The 7pm CDT North Platte observed sounding showed a very steep
   700-500mb lapse rate (approaching 9 degrees C/km) atop a capping
   inversion associated with an elevated mixed layer.  Strong effective
   shear (45-50 kt) has favored supercells and a straight-line
   hodograph sampled by the North Platte sounding supported the notion
   of splitting supercells this evening.  However, as boundary layer
   cooling occurs this evening, increased convective inhibition and a
   strengthening capping inversion will gradually favor weakening
   storms.
