ACUS11 KWNS 210447 SWOMCD SPC MCD 210447 MOZ000-KSZ000-210545- Mesoscale Discussion 1223 NWS Storm Prediction Center Norman OK 1147 PM CDT Sat Jun 20 2026 Areas affected...portions of eastern Kansas into far western Missouri Concerning...Severe potential...Watch possible Valid 210447Z - 210545Z Probability of Watch Issuance...60 percent SUMMARY...Severe gusts may persist with ongoing storms for at least a few more hours as the storms exceed the eastern bounds of ongoing Severe Thunderstorm Watches 359 and 361. A downstream Severe Thunderstorm Watch is being considered. DISCUSSION...A cold-pool-driven bow echo MCS (with mesovortices and a pronounced rear-inflow jet) continue to track eastward across central KS, with an uptick in convective intensities noted with line segments flanking the MCS to the northeast, at the nose of a 700 mb WAA regime. These storms are poised to continue tracking eastward amid 1000-2000 J/kg MUCAPE and locally lower MLCINH. Given widespread 40-50 kts of effective bulk shear (oriented normal to the MCS leading line) preceding ongoing storms and the aforementioned buoyancy, it is plausible that a severe gust threat may continue east of the bounds of Severe Thunderstorm Watches 359 and 361. This may especially be the case because MLCINH may only slowly increase in eastern KS given a very moist boundary layer, characterized by 70+ F surface dewpoints. As such, conditions are being monitored for the need of a downstream Severe Thunderstorm Watch issuance. ..Squitieri/Smith.. 06/21/2026 ...Please see www.spc.noaa.gov for graphic product...
