DISCUSSION...Latest visible satellite imagery shows convection slowly increasing across the southeastern Wyoming, with growing TCU southward to the Palmer Divide. This increase is occurring as ascent associated with weak short-wave troughing moving across Wyoming overspreads the area. Recently, a stronger storm has initiated over Banner County in the Nebraska Panhandle, and -- while capping remains in place farther east -- this storm may note the initial stages of the anticipated afternoon/evening severe-weather event over western Nebraska and adjacent northwestern Kansas. Above the aforementioned capping inversion over western Nebraska and northwestern Kansas, steep lapse rates are contributing to 2000 to 3000 J/kg mixed-layer CAPE. As stronger mid-level westerly flow -- associated with the aforementioned mid-level trough -- spreads eastward across the central High Plains, the overall environment will increasingly support potential for severe/supercell storms. Along with potential for very large hail, strong/damaging wind gusts are also expected locally -- aided by sub-cloud evaporation within the rather deeply mixed boundary layer. ..Goss/Smith.. 06/02/2024 ...Please see www.spc.noaa.gov for graphic product...
