Mesoscale Discussion 0949
NWS Storm Prediction Center Norman OK
1113 PM CDT Sat Jun 20 2020
Areas affected...southwest KS...far northwest OK
Concerning...Severe potential...Watch unlikely
Valid 210413Z - 210545Z
Probability of Watch Issuance...20 percent
SUMMARY...Large hail and severe gusts are possible in the near term
associated with thunderstorms near Dodge City. It is uncertain
whether this storm cluster will persist southward into far northwest
OK and still have an accompanying severe risk.
DISCUSSION...Radar imagery shows a small cluster of severe
thunderstorms near Dodge City embedded within a northwesterly flow
regime. A modest LLJ 25-35 kt sampled by KAMA and KDDC VADs is
located on the western part of richer low-level moisture (surface
dewpoints in the low-mid 60s via the OK Mesonet in far northwest
OK). However, boundary layer cooling and a gradual increase in
convective inhibition lends uncertainty to whether storms will
persist to the OK/KS border with a severe risk. In the meantime,
large hail and localized severe gusts may accompany the stronger
cores.
