...THERE IS A MARGINAL RISK OF SEVERE THUNDERSTORMS ACROSS SOUTHWEST
OK INTO NORTHWEST TX...

...SUMMARY...
A couple storms producing marginally severe hail are possible
through the early overnight hours across a portion of northwest
Texas into southwest Oklahoma.

...01z Update - Southwest OK into northwest TX...

As of 0020z, a southeastward-advancing surface cold front extended
from northeast KS into northwest OK and the eastern TX
Panhandle/South Plains vicinity. 00z regional RAOBs indicate at
couple hundred J/kg MUCAPE present in a narrow corridor ahead of the
front from parts of southwestern OK into northwest TX. Some remnant
warm/dry profiles are noted in the AMA and MAF RAOBs, in the 400-600
mb layer. While steep lapse rates are present across the region, and
favorable effective shear exists for organized storms, the overall
thermodynamic structure evident in 00z RAOBs suggests weak updrafts.
Nevertheless, a strong storm or two, briefly producing marginally
severe hail, can not be ruled out, and the Marginal risk area has
been left unchanged.
