Mesoscale Discussion 1010
NWS Storm Prediction Center Norman OK
0539 AM CDT Tue Jun 13 2023
Areas affected...Southern OK/North TX into the ArkLaTex
Concerning...Severe Thunderstorm Watch 279...
Valid 131039Z - 131215Z
The severe weather threat for Severe Thunderstorm Watch 279
continues.
SUMMARY...The threat for hail and localized strong/damaging gusts
will spread east-southeastward this morning.
DISCUSSION...Two elevated supercells have evolved early this
morning, within a moderately unstable (MUCAPE greater than 2000
J/kg) and favorably sheared (effective shear of 50+ kt) environment.
One is ongoing northwest of Fort Worth, while the other has recently
crossed the Red River into Fannin County, TX. Elongated hodographs
will continue to support a large hail threat with these supercells,
with the western-most cell potentially affecting northern parts of
the Metroplex through 12Z.
In addition to the ongoing supercells, a few strong to potentially
severe storms may evolve out of gradually increasing elevated
convection across south-central OK, before convection likely becomes
focused closer to the ArkLaTex later this morning. Some eventual
clustering of storms remains possible, which could potentially
increase the threat for locally damaging gusts as convection spreads
east-southeastward with time.
