DISCUSSION...A cluster of elevated multicellular thunderstorms has recently increased in coverage downstream of moderate low- to mid-level flow extending from western OK into eastern KS. 12Z TOP sounding sampled modest low moisture beneath a relatively cool and dry mid-levels, resulting in moderate buoyancy. The sounding itself sampled 2370 J/kg of MUCAPE, which matches recent estimates of around 2000 J/kg of MUCAPE from mesoanalysis relatively well.=20 The low to mid-level flow responsible for the warm-air advection supporting these storms is expected to persist, with the overall environment persisting as well. As such, the ongoing cluster is forecast to continue for the next few hours. Continued heating downstream should continue to erode any convective inhibition, with at least some possibility for trend towards more surface-based storm character by the afternoon. Until then, there is an risk for isolated large hail. Additionally, despite the elevated storm character, the dry layer between 900 and 800 mb observed on the 12Z TOP sounding could aid in strengthening downdrafts, allowing for gusts to reach the surface. ...Mosier/Guyer.. 09/23/2023 ....Please see https://urldefense.com/v3/__http://www.spc.noaa.gov__;!!DZ3fj= g!-KCW3yZhAfCmboy11LZFoiBvBHqpoY59uh6gHoPB337qZxQWu23gN44iP4dEY1WV36CNghQ6F= ixcFcx90zePXVbpY1w$ for graphic product...
