Mesoscale Discussion 0115
NWS Storm Prediction Center Norman OK
0513 PM CST Sun Feb 09 2020
Areas affected...South-central OK...North-central TX
Concerning...Severe potential...Watch unlikely
Valid 092313Z - 100115Z
Probability of Watch Issuance...20 percent
SUMMARY...A few strong thunderstorms are possible this evening
across south-central OK and north-central TX. Gusty winds and
perhaps marginally severe hail are the primary threats.
DISCUSSION...A narrow wedge of boundary-layer warming has
contributed to relatively steep low-level lapse rates across the Big
Country into north-central TX ahead of the surface front. This plume
is contributing to deeper convection along the wind shift across
south-central OK. Even so, frontal ascent appears necessary for
these parcels to reach their LFC, though a warm nose near 700mb may
be suppressing updraft strength. Latest thinking is scattered
thunderstorms will continue to develop along the frontal zone over
south-central OK with a gradual southward evolution expected as the
boundary settles into TX. With LLJ focused over the OH Valley, and
no discernible large-scale feature approaching north TX, it appears
gusty winds and perhaps some hail are the primary threats.
