DISCUSSION...MRMS mosaic radar data show convective cores deepening to the lee of the Sierra over portions of western NV, with convective initiation underway across central NV. Diurnal heating has helped boost surface temperatures into the low 60s F, beneath 8+ C/km mid-level lapse rates, yielding MLCAPE over 500 J/kg (per 19Z mesoanalysis). Buoyancy should only increase through the afternoon with continued heating, resulting in increased storm coverage and intensity. While tropospheric flow will remain generally unidirectional, vertical speed shear will support organized multicells and transient supercells as the primary modes of convection. Elongated, straight hodographs suggest that severe hail will be the main threat, though a couple of severe gusts are also possible. The overall severe threat should remain isolated though, so a WW issuance is not currently anticipated. ..Squitieri/Mosier.. 04/10/2026 ...Please see www.spc.noaa.gov for graphic product...
