   Mesoscale Discussion 1347
   NWS Storm Prediction Center Norman OK
   0636 PM CDT Sun Jul 25 2021

   Areas affected...Southwest Utah...northwest Arizona...and southern
   Nevada.

   Concerning...Severe potential...Watch unlikely 

   Valid 252336Z - 260130Z

   Probability of Watch Issuance...5 percent

   SUMMARY...Cluster of storms may pose a severe wind threat as it
   continues southwest.

   DISCUSSION...A cluster of cells has developed in southwest Utah and
   started to accelerate southwestward. The environment downstream of
   this activity is unstable with MLCAPE around 1000 J/kg per SPC
   mesoanalysis. Mesoanalysis also shows increasing CINH across this
   region which may limit the overall severe threat. However if this
   cluster can maintain intensity, it may pose a severe wind threat as
   it moves southwestward over the next couple of hours into an area
   with DCAPE of 1400 to 1700 J/kg.
