[html]MD 1729 CONCERNING SEVERE POTENTIAL...WATCH UNLIKELY FOR TEXAS/OKLAHOMA PANHANDLES...FAR SOUTHWEST KANSAS
Mesoscale Discussion 1729
NWS Storm Prediction Center Norman OK
0313 PM CDT Sat Aug 27 2022
Areas affected...Texas/Oklahoma Panhandles...far Southwest Kansas
Concerning...Severe potential...Watch unlikely
Valid 272013Z - 272145Z
Probability of Watch Issuance...5 percent
SUMMARY...Developing storms may pose an isolated damaging wind/hail
threat this afternoon/evening.
DISCUSSION...Visible satellite trends show a band of residual
mid-level clouds shifting east, with localized clearing occurring
over the TX/OK Panhandle region in the midst of weak convective
inhibition. Consequently, warming surface temperatures (into the low
90s F) have given way to destabilization and subsequent cumulus
development over the region. These trends are being aided by weak
low-level convergence and associated weak lee cyclogenesis, which
should promote continued and gradually more expansive convective
development this afternoon/evening. Despite weak deep-layer shear
(generally less than 25 kt) and weak mid-level lapse rates, strong
low-level lapse rates should support an isolated threat for a few
damaging wind gusts and perhaps some large hail with the strongest
cells, as well as any storm clusters that are able to organize,
throughout the evening.
