Areas affected...portions of the Red River Valley in southwestern Oklahoma/northwestern Texas

Concerning...Severe Thunderstorm Watch 685...

Valid 150135Z - 150230Z

The severe weather threat for Severe Thunderstorm Watch 685
continues.

SUMMARY...A locally greater risk for damaging/severe wind gusts and
perhaps a brief tornado may exist over the next 1-2 hours along
portions of the Red River Valley.

DISCUSSION...Regional radar imagery depicts a well-defined QLCS with
a prominent bowing segment and embedded mesovortex (as sampled by
the KFDR radar) advancing northeastward along the Red River Valley
across portions of southwestern Oklahoma/northwestern Texas. This
bow is propagating eastward within a more stable low-level air mass
located to the north of a remnant outflow boundary. Latest
observations continue to depict backed surface flow within this air
mass, however, with recent objective analysis also indicated the
presence of clockwise curved low-level hodographs and 200-300 m2/s2
ESRH. This is likely to continue to support at least some risk for damaging/severe wind gusts and perhaps a brief QLCS tornado along
portions of the Red River Valley in the near-term, with the greatest
risk likely to exist poleward of the bow's apex.
