Mesoscale Discussion 1726

   0519 PM CDT Sat Sep 11 2021

   Areas affected...far eastern Nevada and portions of western Utah

   Concerning...Severe potential...Watch unlikely 

   Valid 112219Z - 112345Z

   Probability of Watch Issuance...5 percent

   SUMMARY...Isolated severe wind gusts are possible through the
   afternoon and evening.

   DISCUSSION...A cluster of storms has developed in eastern Nevada.
   These storms are currently not particularly strong, but the airmass
   downstream is unstable with MLCAPE around 500 J/kg per SPC
   mesoanalysis. The sub-cloud layer is well-mixed and therefore,
   sufficient evaporative cooling may occur for severe wind gusts in
   the stronger downdrafts. SPC mesoanalysis also shows this region to
   be favorable for downbursts with DCAPE around 1000 J/kg. However,
   the airmass is not nearly as warm as yesterday where DCAPE was at or
   above 1500 and severe wind gusts were more numerous. Therefore, an
   isolated severe wind gust or two is possible this afternoon/evening,
   but a more widespread threat is not anticipated.
