Mesoscale Discussion 1037
   NWS Storm Prediction Center Norman OK
   0211 PM CDT Sun Jun 28 2020

   Areas affected...from northeast Wyoming into southeast Montana and
   the western Dakotas

   Concerning...Severe potential...Watch likely 

   Valid 281911Z - 282115Z

   Probability of Watch Issuance...80 percent

   SUMMARY...Storms will increase in coverage and intensity this
   afternoon with damaging winds and hail expected.

   DISCUSSION...Heating has eroded capping over the higher terrain of
   WY, with storms forming over Johnson county. Ample moisture exists
   downstream with dewpoints in the 50s F, despite the post-frontal
   regime. Continued heating over WY and MT will weaken capping enough
   for outflow-driven storms to persist northeastward for several
   hours, producing damaging wind gusts. Cool temperatures aloft will
   also favor hail. Storms will may weaken over the western Dakotas
   this evening as stronger CIN is encountered.
