MD 0718 CONCERNING SEVERE THUNDERSTORM WATCH 221… FOR CENTRAL KANSAS
Mesoscale Discussion 0718 NWS Storm Prediction Center Norman OK 0830 PM CDT Sun May 24 2020 Areas affected...Central Kansas Concerning...Severe Thunderstorm Watch 221... Valid 250130Z - 250230Z The severe weather threat for Severe Thunderstorm Watch 221 continues. SUMMARY...Several clusters of severe storms are ongoing across WW221. Severe hail and wind are likely to continue with storms across Kansas through 0500z. Thus, the severe threat continues for WW221. DISCUSSION...Several clusters of strong to severe storms have maintained their intensity along and east of slow moving cold front across western Kansas. MLCAPE of 2000-3500 J/kg will continue to support robust updrafts through the 0500z expiration time of WW221. Severe hail remains the primary threat for the next couple of hours with the strong instability and steep mid-level lapse rates. Recent reports of greater than 2 inch hail across southwest and central Kansas lends support for a continued severe hail threat. While vertical shear remains relatively limited at 20-30 kt, the increase in the nocturnal low-level jet may promote some additional development and organization over the next couple of hours. This would support a greater threat for damaging winds with increased momentum transfer in ongoing downdrafts. Hi-resolution guidance supports this scenario, particularly across central Kansas, where upscale growth appears likely. ..Lyons.. 05/25/2020 ...Please see www.spc.noaa.gov for graphic product...
