DISCUSSION...Convective initiation has recently been noted near Dodge City, in the vicinity of a weak surface trough/low. Diurnal heating of a relatively moist airmass has resulted in the development of moderate buoyancy, with MLCAPE increasing into the 1000-1500 J/kg range where stronger heating is underway. Weak midlevel lapse rates (sampled by the 12Z DDC and OUN soundings) may tend to slow updraft intensification, but with time, scattered thunderstorm development is expected within a weakly capped environment, as a mid/upper-level shortwave trough moves southeastward across central/eastern KS. A belt of moderate north-northwesterly midlevel flow associated with the approaching shortwave trough will overspread southwest/south-central KS into northwest/north-central OK with time, resulting in elongated hodographs and sufficient deep-layer shear for storm organization. Multicell clusters and possibly a supercell or two may evolve within this regime. The weak midlevel lapse rates will tend to limit the magnitude of the hail threat, but isolated severe hail will be possible if any supercells can be sustained. Steepening of low-level lapse rates will support some potential for localized strong to severe gusts, especially if any organized clustering evolves with time. ..Dean/Gleason.. 09/01/2025 ...Please see www.spc.noaa.gov for graphic product...
