 Mesoscale Discussion 1269 NWS Storm Prediction Center Norman OK 0602 PM CDT Thu Jun 23 2022 Areas affected...Portions of central Kansas Concerning...Severe Thunderstorm Watch 405... Valid 232302Z - 240100Z The severe weather threat for Severe Thunderstorm Watch 405 continues. SUMMARY...The severe threat continues across Severe Thunderstorm Watch 405. The greatest severe threat continues to be associated with a supercell structure over Russell County, where all severe hazards remain a concern. Other storms may pose a large hail/damaging gust-threat into the evening hours. DISCUSSION...Scattered thunderstorms persist across Severe Thunderstorm Watch 405, amid an environment characterized by 2500+ MLCAPE, 40 kts of effective bulk shear, and locally higher low-level shear constrained to an east-west oriented baroclinic zone over central Kansas. Near the boundary, an HP supercell is thriving over Russell County, KS, where tornadoes were observed and where MRMS mosaic MESH depicts up to 2.5 inch diameter hail possible. KUEX, KDDC, and KICT velocity data depict a well-defined mid-level mesocyclone associated with the Russell County storm, suggesting that the greatest severe threat across the watch will likely be associated with this supercell for at least the next few hours, including the possibility for damaging gusts, severe hail, and perhaps another tornado. West of the supercell, scattered thunderstorms continue to pulse in intensity and these cells may briefly produce a damaging gust or severe hailstone, especially if the storms can avoid entraining convectively overturned air from the Russell County supercell. South and east of the supercell, a pristine airmass remains in place to support additional severe potential if storms can manage to develop before sunset. ..Squitieri.. 06/23/2022 ...Please see www.spc.noaa.gov for graphic product...
