   Mesoscale Discussion 0938
   NWS Storm Prediction Center Norman OK
   0203 PM CDT Fri Jun 02 2017

   Areas affected...eastern Colorado through western Nebraska

   Concerning...Severe potential...Watch unlikely 

   Valid 021903Z - 022130Z

   Probability of Watch Issuance...20 percent

   SUMMARY...Storms will likely increase in coverage this afternoon
   from eastern CO into portions of western NE posing a risk for
   isolated downburst winds and small hail. Overall threat appears too
   limited for any WW issuance.

   DISCUSSION...Early this afternoon a few showers and thunderstorms
   are developing along a lee trough from eastern CO to southwest NE.
   Strong diabatic warming is destabilizing the near-surface layer
   where dewpoints are in the 40s to low 50s F. Deeply mixed,
   inverted-V boundary layers, 500-1000 J/KG MLCAPE, and weakening
   convective inhibition should support additional thunderstorm
   development this afternoon. Vertical shear is weak with pulse and
   multicell storms likely to be the dominant modes, but the
   thermodynamic environment will promote a risk for mainly isolated
   downburst winds though early evening. In addition, a landspout or
   two cannot be ruled out over northeast CO.
