Watch issuance is not expected at this time. DISCUSSION...As a midlevel speed maximum and accompanying dry slot continue overspreading parts of the eastern Great Basin and central Rockies, pockets of diurnal heating and upslope flow amid the strengthening large-scale ascent should support an uptick in convective development through the afternoon hours. While buoyancy will remain somewhat limited over the area, strong/deep south-southwesterly flow will contribute to long/straight hodographs, which combined with steep midlevel lapse rates could support a few instances of large hail. In addition, storm splits and eventual convective clustering could yield locally severe gusts with any upscale-grown clusters as they spread northward through the afternoon. Watch issuance is not expected owing to the marginal and localized nature of the threat. ..Weinman/Grams.. 06/19/2022 ...Please see www.spc.noaa.gov for graphic product...
