Valid 110743Z - 110915Z The severe weather threat for Severe Thunderstorm Watch 587 continues. SUMMARY...Strong to severe gusts remain possible as storms shift east across southern KS and northern OK the next couple of hours. DISCUSSION...A well-organized bowing MCS will continue shifting east the next few hours. The downstream airmass is modestly unstable, with latest mesoanalysis data indicating around 1000-1500 J/kg MUCAPE. Vertical shear also will remain somewhat modest, but sufficient for organized convection, at least in the short term. Measured severe gusts in southern KS over the past hour have been in the 60-70 mph range, and this may persist another 1-2 hours given a well defined rear-inflow jet and mature bowing MCS. With time, gradual weakening is expected across southeast KS/northeast OK where earlier and ongoing precipitation ahead of the MCS will likely limit downstream severe, especially east of the I-35 corridor. ...Leitman.. 08/11/2025 ....Please see https://urldefense.com/v3/__http://www.spc.noaa.gov__;!!DZ3fj= g!71m-hCFkt7bFmFLLuTvPhPwKfS0RXpimMHZf9StgDJWwUEudugdP68BBuZs_j2AKmmV7EqVfi= LnxFsgANBGDYQlFrrY$ for graphic product...
