SATELLITE ANALYSIS AND TRENDS...LATEST SURFACE MESOANALYSIS INDICATES
THAT SURFACE COLD POOL WAS CENTERED JUST W OF AUS WITH LEADING OUTFLOW
BOUNDARY FROM WEAKENING MCS EXTENDING FROM VIC OF TKI S TO NEAR CLL AND
THEN SW TO S OF COT.  LOW LEVEL SHEAR VECTORS WERE ORIENTED FAVORABLY
WITH OUTFLOW BOUNDARY TO CONTINUE TO FAVOR ENHANCED MESOSCALE ASCENT JUST
DOWNSTREAM FROM E OF DAL EXTENDING S TOWARDS THE VIC OF VCT AND IMAGERY
OVER THE PAST HOUR WAS INDICATING SOME AREAS OF CLOUD TOP COOLING ALONG
THIS AXIS.  JUST DOWNSTREAM FROM THERE, CHAN 2 IMAGERY WAS SHOWING
A NUMBER OF HCRS THAT HAVE BEEN TRYING TO ENHANCE WITHIN MODERATELY
UNSTABLE ENVIRONMENT AND TRYING TO MERGE INTO MAIN CONVECTIVE LINE
NEAR CLL.  BELIEVE THE TREND FOR CONVECTION TO CONTINUE TO ENHANCE IN
PORTIONS OF E/SE TX IS POSSIBLE OVER THE NEXT FEW HOURS AS AREA OF ASCENT
AHEAD OF OUTFLOW BOUNDARY CONTINUES TO MOVE INTO A MODERATELY UNSTABLE
ENVIRONMENT WITH LITTLE INHIBITION AND LOW LCL/LFC ON GOES SOUNDER.
DO BELIEVE THAT OUTFLOW BOUNDARY SHOULD CONTINUE TO BE SLOWLY PROGRESSIVE
BUT STORM MOTIONS RELATIVE TO OUTFLOW BOUNDARY COULD ALLOW FOR A PERIOD
OF TRAINING CONVECTION TO ENHANCE HEAVY RAIN THREAT ESPECIALLY IN ANY
AREAS OF MERGING CONVECTION WITH DOWNSTREAM HCRS.
