Mesoscale Discussion 0848

0142 AM CDT Mon May 20 2024
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.
