DISCUSSION...Clearing in the wake of earlier mid/high-level cloudiness has allowed for modest diurnal heating from eastern CO into west-central/southwest KS. Temperatures aloft are relatively warm, but boundary-layer warming and sufficient low-level moisture are supporting MLCAPE of near/above 1000 J/kg, with locally greater values across southwest KS. Weak storms have already developed near the CO Front Range, with building cumulus noted in the vicinity of multiple surface confluence zones across northeast CO, east-central CO, and southeast CO into southwest KS. Westerly midlevel flow is relatively modest (generally 20-25 kt), but sufficient veering in the wind profile is supporting effective shear of 25-30 kt. With time, a few organized multicells and perhaps a marginal supercell or two could evolve as developing convection deepens and matures through late afternoon. The strongest cells could produce isolated hail, though generally weak midlevel lapse rates will tend to limit the magnitude of the hail threat. Outflow amalgamation could result in loosely organized upscale growth by early evening, with a threat for strong to locally severe gusts. ..Dean/Gleason.. 08/27/2025 ...Please see www.spc.noaa.gov for graphic product...
