Concerning...Severe Thunderstorm Watch 672...

Valid 100148Z - 100345Z

The severe weather threat for Severe Thunderstorm Watch 672
continues.

SUMMARY...Scattered strong thunderstorms will spread into the
eastern parts of ww672 over the next few hours. Hail remains the
primary threat.

DISCUSSION...Thunderstorms struggled to develop across the southern
High Plains along the dryline earlier this evening along eastern
fringe of steeper lapse-rate plume. However, convection gradually
rooted into a more moist boundary layer near the TX/OK border and
this activity has since remained mostly organized as it propagates
northeast across western OK. 00z sounding from OUN exhibits a wind
profile favorable for deep rotating storms along with adequate
buoyancy for robust updrafts, though notably capped. Hail algorithm
continues to suggest large hail is accompanying the strongest
supercells, especially over Comanche County where this storm is
decidedly turning more east. As LLJ strengthens over the next few
hours it appears this will influence the longevity of convection and
assist the progression toward the I-35 corridor; although, a gradual
weakening is expected toward the eastern edge of the watch.
