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.
