COASTAL BEND FORECAST DISCUSSION
NATIONAL WEATHER SERVICE CORPUS CHRISTI TX
238 AM CDT MON JUL 15 2002

AN ACTIVE WX PATTERN IS IN STORE FOR SOUTH TX THROUGH TUE.  SOUTH TX
WL CONTINUE TO HAVE A DECENT DIFLUENT PATTERN IN THE UPR LVLS.  THIS
WL BE FURTHER ENHANCED BY THE RRQ OF A JET STREAK MOVING THROUGH
NERN TX.  ALSO...FAVORABLE DYNAMICS WL BE COMING FROM AN IMPRESSIVE
UPR LOW/VORT MAX CURRENTLY IN NERN MEXICO.  THE LATTER APPEARS TO BE
MAINLY RESPONSIBLE FOR THE CURRENT MCSS AFFECTING THE NWRN PART OF
THE CWFA.  THIS UPR LOW IS PROGGED TO REMAIN TO OUR WEST THROUGH
TUE.  MEANWHILE...PWS WL BE SURGING EVEN HIGHER AND WL REACH 2.2 TO
2.4 INCHES IN MANY AREAS.  SATL IMAGERY AND THE MODELS HAVE PICKED
UP ON ANOTHER SLUG OF MOISTURE FROM THE SRN GULF WHICH WL AFFECT THE
CWFA LATER TDA.  ON TOP OF THIS...THERE IS A WK SFC BOUNDARY
STRETCHING FROM VCT TO SWWD TO TO THE SOUTH OF LRD.  THIS FEATURE
SHOULD TEND TO MOVE SLOWLY EWD TDA.  ALL OF THESE PARAMETERS WL KEEP
THE HEAVY RAIN/FLOODING THREAT GOING THROUGH TUE.  THUS...THE FFA WL
BE CONTINUED AND EXTENDED THROUGH TUE TO COVER THE ENTIRE CWFA.

WL BE A BIT MORE PESSIMISTIC FOR THE PERIOD TUE NIGHT AND WED.  BLV
THE ETA SOLN IS HANDLING THE SYNOPTIC FEATURES...ESPECIALLY THE UPR
LOW IN MEXICO BETTER THAN THE AVN.  THE AVN LOOKS TO BE A BIT TOO
AGGRESSIVE WITH DRYING US OUT SO QUICKLY.  AFTER WED...WL NOT MAKE
ANY CHANGES TO THE PREV FCST TREND.

MARINE...MODERATE TO STRONG ONSHORE FLOW WL CONTINUE THROUGH THE
SHORT RANGE FCST.   WL MAINTAIN SCTD TO NUM SHRAS/TSRAS IN THE FCST
FOR THE SAME REASONS NOTED ABV.  THINGS BEGIN TO SLOWLY IMPROVE BY
WED WITH GENERALLY MORE TRANQUIL CONDITIONS AFTER THAT.
