A WW issuance is not currently expected. DISCUSSION...Thunderstorms are increasing in number and intensity across eastern UT/western CO along the entrance region of a 300 mb jet streak, where a well-mixed boundary layer is now in place. Latest MRMS-MESH radar data suggests some of the stronger storms may already be producing at least marginally severe (i.e. 1 inch diameter) hail. Surface temperatures approaching the upper 80s F beneath 9 C/km tropospheric lapse rates is contributing to 500-1000 J/kg MLCAPE. RAP forecast soundings depict hodographs with modest low-level curvature but considerable mid-level elongation, which will promote continued multicell/supercell development through the afternoon. The strongest storms will be accompanied by some severe wind/hail threat. However, the severe threat should remain isolated, and a WW issuance is not currently anticipated. ..Squitieri/Hart.. 06/22/2024 ...Please see www.spc.noaa.gov for graphic product...
