Valid 092053Z - 092230Z The severe weather threat for Severe Thunderstorm Watch 204 continues. SUMMARY...The threat for potentially significant wind gusts and large hail will spread southeastward into the early evening. Downstream watch issuance now appears likely within the hour. DISCUSSION...The long-lived MCS continues to move across eastern KS late this afternoon, with sporadic measured gusts of 60-80 mph noted within the last 1-2 hours. A nearly stationary surface boundary is still noted in surface observations and on visible satellite imagery, though some modification has occurred on the cool side of the boundary, with increasing cumulus and MLCAPE noted from east of Topeka to south of Kansas City.=20 Moderate to strong buoyancy will help to sustain this MCS as it moves southeastward into this evening, though increasingly marginal deep-layer flow/shear downstream could eventually limit the organization/intensity of the MCS to some extent. The greatest short-term severe wind threat may focus along the surface boundary into southeast KS, where instability and low-level convergence is more favorable and the gust front has not yet notably surged ahead of the leading convection.=20 Based on the expected timing of the MCS, downstream watch issuance into far southeast KS and southwest MO is likely within the hour. ...Dean/Guyer.. 05/09/2023 ....Please see https://urldefense.com/v3/__http://www.spc.noaa.gov__;!!DZ3fj= g!47XVrvqdjwoVM6bvFcWOzupi_hkndjKO1MuNy4USkkTSO3OyGknthwah_2YmM8Tv7FhDmObOg= sLpq6jt-NP7RcfHhv0$ for graphic product...
