   Areas affected...northeastern Colorado...southeastern Wyoming...and
   the Nebraska Panhandle

   Concerning...Severe potential...Watch unlikely 

   Valid 151842Z - 152045Z

   Probability of Watch Issuance...20 percent

   SUMMARY...High-based storm development will continue -- initially
   over the higher terrain but spreading eastward with time.  A few
   strong gusts are possible, but isolated nature of this risk suggests
   that WW issuance will likely not be required.

   DISCUSSION...Daytime heating across the central High Plains region
   is supporting modest destabilization, and initiation of high-based
   convection -- most notably from southeastern Wyoming southward into
   the central Colorado Front Range.  The convection is developing
   above a deep mixed layer, where dewpoints are generally now observed
   in the 40s and 50s across the area.

   Flow aloft remains generally weak over the central High Plains, and
   CAPE limited, suggesting that storms should remain largely
   disorganized this afternoon.  However, given potential for
   evaporative cooling in the sub-cloud layer, a few enhanced gusts
   capable of producing wind damage will be locally possible across the
   area into this evening.
