Areas affected...Central and northern Oklahoma into far northwest
Arkansas

Concerning...Severe Thunderstorm Watch 628...

Valid 162300Z - 170030Z

The severe weather threat for Severe Thunderstorm Watch 628
continues.

SUMMARY...The severe threat continues across Severe Thunderstorm
Watch 628. At least a few instances of severe wind or hail may
accompany the stronger storms over the next few hours.

DISCUSSION...Multicell clusters and transient supercells have
percolated in intensity from far western OK into far northwestern AR
over the past few hours. At the moment, a couple of strong
thunderstorm clusters are ongoing along diffuse baroclinic
boundaries, were surface temperatures are in the upper 90s to low
100s F, contributing to 8.5-9.5 C/km boundary-layer lapse rates. As
such, the more intense, persistent updrafts may support a large-hail
threat until they become outflow dominant, when severe gusts become
the main concern. However, deep-layer ascent/shear remain weak, so
thunderstorms may continue to struggle to maintain intensity, with
the severe threat perhaps becoming gradually more isolated through
the evening.
