Areas affected...north-central and northeastern Oklahoma

Concerning...Severe Thunderstorm Watch 265...266...

Valid 200642Z - 200845Z

The severe weather threat for Severe Thunderstorm Watch 265, 266
continues.

SUMMARY...Severe-weather risk will continue across portions of
north-central and northeastern Oklahoma -- largely within WW 266.

DISCUSSION...Latest radar loop shows a cluster of strong/locally
severe storms ongoing across north-central and into northeastern
Oklahoma -- in the far southeastern corner of soon-to-expire WW 265
and western portions of WW 266.  

Storms continue to regenerate on the southwestern flank of the
convection, resulting in a slow southward drift to the convection. 
This is occurring as a strong (near 60 kt) southwesterly low-level
jet continues to provide a feed of high theta-e air atop low-level
convective outflow.  

With deep-layer shear favorable for organized/rotating storms,
expect local/isolated -- but all-hazard -- severe risk to persist
for some time.  As WW 265 expires, and as storms creep southward
with time, local WW extensions may be needed to cover the
persistent/evolving risk.
