THE THREAT FOR ISOLATED SEVERE WEATHER IS EXPECTED TO CONTINUE
ACROSS PARTS OF CNTRL OK INTO FAR N-CNTRL TX INTO MID MORNING.
CURRENT TORNADO WATCHES MAY BE REPLACED WITH A SEVERE TSTM WATCH
SHORTLY.

A QLCS HAS BECOME ESTABLISHED ALONG PACIFIC FRONT AS OF 1025Z FROM
JUST W OF PNC SSWWD TO JUST W OF OKC TO SPS. AS MENTIONED IN PRIOR
DISCUSSIONS...STRONGER CONVECTIVE UPDRAFTS CONTINUE TO BE UNDERCUT
BY COMBINATION OF CONVECTIVE OUTFLOW AND SYNOPTIC FRONT...DESPITE
THE EWD PROGRESSION OF SYSTEM INTO AN EXCEEDINGLY MOIST AIR MASS.
THUS...EVEN THOUGH AMBIENT WIND FIELD REMAINS QUITE STRONG...THE
OUTFLOW-DOMINANT...LINEAR CONVECTION MODE IS EXPECTED TO LIMIT THE
TORNADO THREAT...AT LEAST IN THE IMMEDIATE FUTURE. THE POTENTIAL
FOR DAMAGING WIND GUSTS WILL CONTINUE TO EXIST WITH ANY EMBEDDED
BOWING SEGMENTS...THEREFORE PARTS OF CURRENT TORNADO WATCHES WILL
LIKELY BE REPLACED WITH A NEW SEVERE TSTM WATCH.
