Mesoscale Discussion 0764

   0708 PM CDT Fri May 29 2020

   Areas affected...eastern Wyoming...western Nebraska...far northeast
   Colorado

   Concerning...Severe potential...Watch unlikely 

   Valid 300008Z - 300145Z

   Probability of Watch Issuance...5 percent

   SUMMARY...Isolated marginally severe hail and wind are possible
   across portions of eastern Wyoming into western Nebraska and far
   northeast Colorado this evening.

   DISCUSSION...Thunderstorms are developing this evening across the
   central High Plains along the northeastern periphery of an upper
   high over the Four Corners. Weak upslope flow and daytime heating
   have helped initiate storms within an environment characterized by
   modest instability (500 J/kg of MLCAPE) and shear (30-40 knots bulk
   shear). High-based, splitting storms are likely given the relatively
   straight hodographs and dry low-levels. Marginally severe hail is
   possible along with damaging wind gusts. These storms are likely to
   diminish shortly after sunset, and a watch issuance is unlikely
   given the isolated, marginal nature of the storms.
