Areas affected...far northeast NM...TX Panhandle...west-central OK

Concerning...Severe potential...Watch possible 272...

Valid 120903Z - 121100Z

Probability of Watch Issuance...60 percent

SUMMARY...Strong to severe thunderstorms are possible into the
morning hours from the TX Panhandle into perhaps west-central OK.=20
Large hail is the severe hazard of concern.

DISCUSSION...Radar mosaic shows a few intense thunderstorms from far
northeast NM east into the northern part of the TX Panhandle.=20
Water-vapor imagery indicates this region is downstream of a
mid-level low centered over southern NV and located beneath a
mid-level ridge axis.=20=20

Analysis of the KAMA VAD shows a strongly veering surface-3km wind
profile beneath 55-kt 6-km westerly flow. This implies a focused west-northwest to east-southeast corridor of frontal lift/isentropic
ascent, and short-term model guidance indicates this lift will
strengthen through the mid morning from the TX Panhandle into southwest/west-central OK. Additionally, the time-lagged HRRR shows
the current activity over northeast NM/TX Panhandle moving
east-southeast into western OK through the mid morning. Given the
adequate elevated buoyancy/shear, it seems plausible at least a few
severe thunderstorms will probably continue beyond the expiration of
severe thunderstorm watch #272 at 10 UTC (5am CDT). The existing
activity and potentially additional storms farther east will pose a
large hail risk. The coverage of severe is still uncertain but an
additional severe thunderstorm watch is being considered.
