Areas affected...Northeast Texas...Southeast Oklahoma...Western
Arkansas

Concerning...Severe Thunderstorm Watch 161...

Valid 261229Z - 261430Z

The severe weather threat for Severe Thunderstorm Watch 161
continues.

SUMMARY...A severe threat will continue this morning across WW 161.
Wind damage and isolated large hail will be possible over the next
few hours as strong to severe storms move across the western and
southern part of the watch.

DISCUSSION...The latest radar analysis shows a multi-segmented line
of storms extending from far northwest Arkansas southwestward across
southeastern Oklahoma with a separate cluster of storms located in
northeast Texas. An axis of moderate instability is analyzed ahead
of this convection with surface dewpoints generally in the mid to
upper 60s F across most of northeast Texas and Arkansas. An outflow
boundary from the previous day`s storms is located across northern
Arkansas. The latest HRRR appears to be reasonable, gradually
developing a squall line across northern and west-central Arkansas
late this morning. Discrete supercells will also be possible ahead
of the line with these storms capable of producing large hail, wind
damage and possibly a brief tornado. Bowing segments along the more
organized parts of the squall line could be associated with wind
damage and hail. Rotating cells within the line itself may also
produce hail.
