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.
