Mesoscale Discussion 1625
NWS Storm Prediction Center Norman OK
0753 AM CDT Sat Aug 29 2020
Areas affected...Parts of southeastern Kansas into southwestern
Missouri
Concerning...Severe potential...Watch unlikely
Valid 291253Z - 291430Z
Probability of Watch Issuance...5 percent
SUMMARY...A small cluster of storms may maintain intensity another
hour or two, accompanied by a few strong surface gusts, before
weakening while spreading into portions of southwestern Missouri and
adjacent northwestern Arkansas after 10 AM CDT.
DISCUSSION...Storms which initiated overnight near Medicine Lodge
KS, in closer proximity to the surface frontal zone, have become
most prominent, consolidating into a small, intensifying storm
cluster near/north of the eastern Kansas/Oklahoma border the past
few hours. This probably has been aided by moderate updraft inflow
of moist air with CAPE up to 2000 J/kg, in the presence of modest
vertical shear beneath 20-30+ kt westerly flow around 500 mb.
However, as activity progresses east of the southern Kansas/Missouri
state border vicinity by 15-16Z, latest objective instability
analyses suggest that this unstable inflow will begin to become cut
off, which seems likely to result in diminishing convective
intensity. Until then though, ongoing storms may continue to be
accompanied by occasional strong surface gusts.
