DISCUSSION...Storm coverage is increasing early this evening from central KS into northwest MO. Storms to the north/northeast of Kansas City have developed just to northeast of a warm front and are likely somewhat elevated. Persistent low-level warm/moist advection will help to sustain these storms as they approach north-central MO. Moderate elevated buoyancy (with MUCAPE of 1000-1500 J/kg) and sufficient deep-layer shear could support marginal supercell structures with a threat for isolated large hail. Also, despite this convection being somewhat elevated, a dry near-surface layer beneath the elevated moist plume could support some stronger wind gusts this evening as storms spread northeastward.=20 Farther west, scattered storm development is ongoing from south-central into northeast KS, as a southeastward-moving cold front begins to intercept a pre-frontal surface trough and relatively greater instability. While low-level moisture remains rather limited, strong diurnal heating has resulted in MLCAPE increasing into the 500-1000 J/kg range, along with weakening MLCINH. Increasing deep-layer flow/shear associated with an approaching midlevel shortwave trough will support some organized convection through the evening.=20 Rather strong low-level flow (30-40 kt in the 1-3 km layer per regional VWPs) and steep low-level lapse rates will support potential for strong to locally severe gusts within this regime, especially if any organized clustering occurs. Isolated hail will also be possible, especially into east-central/northeast KS and northwest MO, where somewhat more favorable moisture and buoyancy will be in place. ...Dean/Hart.. 10/24/2024 ....Please see https://urldefense.com/v3/__http://www.spc.noaa.gov__;!!DZ3fj= g!_198EWu_ujeFBP9r_i0CAt6NbdVD_Xa1i7lVXD8g8xZf2SK-gcGLDtKd-3UlVXXBoMC8cSqjr= EKtz6BWCSTHJdwShCs$ for graphic product...
