Mesoscale Discussion 0394
NWS Storm Prediction Center Norman OK
0400 PM CDT Sat May 12 2018
Areas affected...Portions of the TX/OK Panhandles into west TX and
far western OK
Concerning...Severe potential...Watch unlikely
Valid 122100Z - 122330Z
Probability of Watch Issuance...5 percent
SUMMARY...Isolated strong to severe wind gusts and perhaps some hail
will be possible through this evening. Watch issuance is not
expected.
DISCUSSION...Weak convergence along a surface dryline and subtle
large-scale lift associated with a low-amplitude mid-level shortwave
trough ejecting northeastward over the southern High Plains this
afternoon should be sufficient to initiate at least isolated
convection along the dryline over the next couple of hours. Recent
visible satellite imagery shows increased mid-level cloudiness
across west TX into the TX Panhandle. With temperatures east of the
dryline reaching into the mid to upper 90s and greater low-level
moisture in the eastern TX/OK Panhandles and far western OK, MLCAPE
has increased into the 1000-2000 J/kg range. Mid-level flow is
modestly stronger across the TX/OK Panhandles, and weakens quickly
with southward extent into west TX. In addition, upper-level winds
will remain weak across this area. Still, a deeply mixed boundary
layer with very steep (8-9 degree C/km) low and mid-level lapse
rates should enhance convective downdrafts. Isolated strong to
severe winds appear to be the main threat, although some hail may
occur with the strongest thunderstorms. Overall, thunderstorm
coverage will likely remain too isolated to justify watch issuance.
