   Areas affected...portions of the northern Great Basin

   Concerning...Severe potential...Watch unlikely 

   Valid 081959Z - 082200Z

   Probability of Watch Issuance...20 percent

   SUMMARY...Strong to occasionally severe thunderstorms will pose a
   risk for isolated damaging/severe wind gusts through this evening.
   Watch issuance is unlikely at this time.

   DISCUSSION...Isolated to widely scattered convection has developed
   across portions of the northern Great Basin as of 1950 UTC. A
   modified 18z SLC sounding depicts minimal remaining inhibition, with
   a deep, well-mixed boundary layer and weak buoyancy (200-500 J/kg
   MLCAPE) in place. As continued insolation results in additional
   thunderstorm development through the afternoon, steep low-level
   lapse rates and high LCLs (2500-3000+ m) will promote the potential
   for isolated damaging/severe wind gusts. Modest effective shear (~20
   kts or less) and weak deep-layer flow (generally 25 kts or less
   sampled by the SFX/MTX/RIW VWPs) should largely limit storm
   organization and temper the overall severe threat. While a corridor
   or two of locally greater severe potential may manifest where storms
   cluster along developing cold pools, the severe risk is expected to
   remain too isolated for watch issuance at this time.
