   Concerning...Severe potential...Watch likely 

   Valid 262013Z - 262115Z

   Probability of Watch Issuance...80 percent

   SUMMARY...A few thunderstorms with large hail and severe gusts are
   possible this afternoon across portions of northeastern Colorado,
   southeastern Wyoming, and far western Nebraska. A watch may be
   needed to cover this threat.

   DISCUSSION...A large upper trough is in place across the
   northwestern CONUS with a subtle jet pushing eastward over the
   central Rockies this afternoon. Storms are preferentially developing
   along a couple convergence boundaries across portions of the High
   Plains. The flow enhancement from the jet results in lengthened
   hodographs, which should result in enough shear for at least a few
   supercells.

   With any supercells that do form, a few instances of large hail are
   possible due to the straight hodographs and relatively low freezing
   levels. Storms may cluster as the afternoon progresses, which may
   result in a threat for severe gusts due to the dry boundary layer
   and modest low- and mid-level flow. One limiting factor for wind is
   some residual inhibition across parts of the High Plains, though
   this is expected to erode with continued strong heating. A watch
   will likely be needed to cover this threat.
