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. ..Chalmers/Hart.. 07/08/2026 ...Please see www.spc.noaa.gov for graphic product...
