DISCUSSION...High-based cumulus is deepening this afternoon across west-central KS, in the vicinity of a diffuse surface boundary. Some increase in shallow cumulus has also been noted across northeast KS into far southeast NE, where airmass recovery is underway in the wake of morning convection. In the short term, the greater chance for storm development may reside within the very warm and well-mixed environment from west-central into northern KS, in the vicinity of the surface boundary where CINH is diminishing. Any development in this area would be high-based, but MLCAPE of 1000-1500 J/kg, steep low/midlevel lapse rates, and modest effective shear (generally 25-30 kt) could support a few stronger storms capable of isolated severe gusts and hail by early evening. Farther northeast into northeast KS/southeast NE and vicinity, a more favorable conditional environment may evolve by early evening, with relatively backed flow, moderate deep-layer shear, and somewhat richer boundary-layer moisture. However, in the absence of stronger large-scale ascent, potential for surface-based storm development within the initially capped environment is uncertain and could remain relatively limited. Should robust convection develop in this area, a supercell or two could evolve and pose an organized severe threat. Watch issuance is currently considered unlikely, due to the potentially limited coverage of the severe threat across the region. However, a watch would become increasingly possible if observational trends begin to support development of multiple severe storms by early evening. ..Dean/Smith.. 03/27/2025 ...Please see www.spc.noaa.gov for graphic product...
