SATELLITE ANALYSIS AND TRENDS...LATEST IR IMAGERY AND MESOANALYSIS
INDICATES THAT COLD POOL HAS ELONGATED FROM PORTIONS OF E CNTRL AL
EXTENDING WNW TO PORTIONS OF SE OK OVER THE PAST FEW HOURS.  COLD POOL HAS
BEEN REINFORCED ON THE E EDGE BY ONGOING FORWARD PROPAGATING MCS NOW OVER
E CNTRL AL.  FURTHER UPSTREAM COLD POOL WAS NOT AS WELL DEFINED BUT IT
DID APPEAR TO EXTEND WNW TO WHERE IT INTERSECTED SYNOPTIC BOUNDARY JUST
SE OF OKC.  CONVECTION HAS BEGUN TO REDEVELOP NEAR THE ARKLATEX REGION
IN RESPONSE TO UPSTREAM HEIGHT FALLS NOW AMPLIFYING INTO PORTIONS OF
CNTRL KS WHERE IT APPEARS SYSTEM MAY HAVE CLOSED OFF IN THE MID LEVELS.
AREA VWPS WERE SHOWING THAT BROAD LLJ HAS INCREASED TO AROUND 30KTS AT
925H AND WAS INTERCEPTING REMNANT COLD POOL FOR AN INCREASING AREA OF
ISENTROPIC ASCENT.  THIS HAS ALLOWED FOR AN ENHANCING AREA OF CONVECTION
OVER PORTIONS OF S AR FROM S OF PBF EXTENDING W TOWARDS DEQ AND ALSO
FURTHER DOWNSTREAM OVER PORTIONS OF N MS FROM CBM VIC WNW TOWARDS UTA.
BELIEVE THIS THREAT SHOULD CONTINUE THROUGHOUT THE NIGHT AS HEIGHT FALLS
CONTINUE TO OVERSPREAD THE AREA AND COUPLE WITH AN INCREASED AREA OF
ISENTROPIC ASCENT FROM BROAD BUT STRENGTHENING LLJ.  THE CLOSING OFF OF
THE MID LEVEL CENTER OVER PORTIONS OF E KS HAS HELPED TO BACK UL FLOW WITH
INCREASED AREA OF DIFFLUENCE CENTERED NEAR THE ARKLATEX REGION.  UPSTREAM
INSTABILITY AND LLJ AXIS STILL REMAIN FAVORABLY ORIENTED TOWARDS THIS
DIFFLUENT REGION TO IMPLY AN ENVIRONMENT THAT IS FAVORABLE FOR A CONTINUED
INCREASE OF CONVECTION WITH THE THREAT FOR BACKBUILDING/REGENERATION.
UNIDIRECTIONAL WIND PROFILES REMAIN ORIENTED PARALLEL TO S PERIPHERY
OF DOWNSTREAM OUTFLOW BOUNDARY AND THIS SHOULD ENHANCE THE THREAT FOR
TRAINING CONVECTION FROM CNTRL/N AL EXTENDING WNW TO S AR.  SMALL SCALE
COMPLEXES SHOULD CONTINUE TO FORWARD PROPAGATE TO THE ESE ALONG THICKNESS
AND INSTABILITY GRADIENT AND THIS SHOULD HELP TO REINFORCE S PORTION OF
THIS BOUNDARY.  THIS MESSAGE WAS COORDINATED WITH WPC METWATCH FORECASTER.
