Mesoscale Discussion 0759
NWS Storm Prediction Center Norman OK
0318 PM CDT Sat May 14 2022
Areas affected...parts of west-central into northwest Texas
Concerning...Severe potential...Watch unlikely
Valid 142018Z - 142245Z
Probability of Watch Issuance...20 percent
SUMMARY...Isolated storms are expected to form by 21Z over
west-central Texas, and a few cells may produce marginally severe
hail or wind gusts.
DISCUSSION...Surface analysis shows a dryline extending south from
the eastern TX Panhandle, with a weak low near SWW where
temperatures are over 100 F. Dewpoints are generally in the 50s F,
but low 60s F exist into central TX with PWAT generally around 0.80
inches per GPS water vapor sensors.
Visible imagery shows convection beginning to form along the
dryline, and a few of the storms may gain strength as they move very
slowly. The steep lapse rate environment combined with sufficient
instability should support a couple marginally severe storms
producing hail near 1.00-1.50" and gusty winds before dissipating
after sunset.
