If initiation occurs, severe hail/wind will be possible. DISCUSSION...Recent GOES imagery and surface observations show slow vertical development of cumulus along an outflow boundary draped from northwest OK into southwest KS/eastern CO. Temperatures warming into the low 90s and low/mid 80s on the warm and cool side of the boundary (respectively) suggest that MLCIN continues to erode across this region. Given that forcing for ascent is weak and largely tied to the outflow boundary, it remains uncertain whether or not sustained convective initiation will occur through peak heating. However, the recent satellite and surface observation trends suggest that this is a possibility. If sustained convection can develop, it will mature within an environment characterized by around 1000-1500 J/kg MLCAPE and elongated hodographs featuring around 30-40 knots of effective bulk shear per recent forecast soundings. Convective coverage would likely be sufficiently isolated to promote supercells, which may be capable of severe gusts and large hail (possibly up to 2-2.5 inches). Enhanced near-surface vorticity along the boundary and southeasterly flow/augmented low-level SRH to the immediate east of the boundary may support some tornado threat. While watch issuance is not expected due to uncertainty regarding initiation, convective trends will be monitored. ..Moore/Gleason.. 08/24/2025 ...Please see www.spc.noaa.gov for graphic product...
