Mesoscale Discussion 1975 NWS Storm Prediction Center Norman OK 0844 PM CDT Thu Aug 22 2024 Areas affected...Central High Plains Concerning...Severe Thunderstorm Watch 644... Valid 230144Z - 230345Z The severe weather threat for Severe Thunderstorm Watch 644 continues. SUMMARY...Wind/hail threat will spread across eastern portions of ww644 over the next several hours. DISCUSSION...Scattered high-based convection that initiated over the higher terrain of central/southern CO has matured into an MCS that is now advancing into northwest KS. Over the last hour or so, a weak MCV appears to have developed which is now just south of AKO, supporting the overall organization of this complex. 1km AGL southeasterly inflow across western KS is on the order of 25-30kt, which will encourage propagation across at least the western portions of the main instability corridor. 00z soundings from the central High Plains exhibit substantial CINH, and further boundary-layer stabilization is expected as surface temperatures cool. Given the organization of this complex, further propagation is likely into the eastern-most portions of the watch; however, updraft intensities have likely peaked and gradual weakening can be expected by 03-04z. Until then, damaging winds will likely be the primary risk. ..Darrow.. 08/23/2024 ...Please see www.spc.noaa.gov for graphic product... ATTN...WFO...LBF...GLD...PUB...BOU...
