Areas affected...Northwest TX into southern OK

Concerning...Severe Thunderstorm Watch 71...

Valid 240232Z - 240430Z

The severe weather threat for Severe Thunderstorm Watch 71
continues.

SUMMARY...The risk of large hail continues with ongoing supercells
from northwest TX into south-central OK (across Severe Thunderstorm
Watch 71). Trends are being monitored for an additional watch
issuance for parts of the area tonight.

DISCUSSION...Splitting supercells capable of large hail are ongoing
from northwest TX into portions of south-central OK -- north of a
quasi-stationary surface boundary draped through the area. While
most of these storms are likely elevated atop the frontal surface,
60+ kt of cloud-layer shear (per regional VWP data) characterized by
long/mostly straight hodographs is still supporting loosely
organized splitting supercell structures. During the next few hours,
this activity will generally track east-northeastward across
southern OK with a continued risk of large hail. It is unclear if
this continued activity will warrant an additional watch issuance
upon the 04Z expiration of Severe Thunderstorm Watch 71, though
convective trends will be monitored.
