AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE CORPUS CHRISTI TX
845 PM CDT TUE JUN 29 2004

.DISCUSSION...MAIN CONCERN IS FOCUS OF HEAVY RAINFALL.  RADAR IS
SHOWING HEAVIEST RAINFALL OVER WEBB COUNTY AT THIS TIME RIGHT ALONG
AREA OF STRONG SURFACE CONVERGENCE.  ATMOSPHERE HAS BEEN WORKED
OVER SLIGHTLY TODAY BUT STILL A LOT OF MOISTURE AND INSTABILITY TO
SPARE FOR TOMORROW WITH NO CAP TO HOLD THE CONVECTION FROM FORMING.
FEEL THE MAIN THREAT FOR FLOODING TONIGHT WILL BE OVER THE WEST
WHERE SURFCACE CONVERGENCE IS PROGGED TO CONTINUE AND MOISTURE
LEVELS ARE THE HIGHEST. CONVERGENCE ALONG THE COAST TONIGHT WILL AID
IN CREATING SHOWERS/STORMS OVERNIGHT BUT EXPECT THIS ACTIVITY TO BE
MORE SCATTERED IN NATURE AT THIS TIME BUT SHOULD PICK UP BY MORNING.
SINCE FFA IS GOING THROUGH WEDNESDAY...WILL MAINTAIN THE WATCH
ALTHOUGH MAIN THREAT FOR THE EASTERN HALF OF THE CWFA WILL BE
TOMORROW. MID SHIFT CAN RE-EVALUATE FOR MORNING PACKAGE.  NOT A
CLEAR-CUT CASE WEDNESDAY AS GROUNDS ARE QUITE SATURATED BUT STORMS
ARE GENERALLY EXPECTED TO MOVE AND MAIN UPPER SUPPORT IS PRETTY MUCH
NORTH OF CWFA. JUST NO PLACE TO PUT THE WATER HOWEVER. WILL MAKE
SOME MINOR ADJUSTMENTS TO THE FIRST PERIOD BUT OVERALL REMAINDER OF
THE FORECAST LOOKS OK.
