AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE CORPUS CHRISTI TX
1038 AM CDT WED JUN 20 2007

.UPDATE...LINE OF CONVECTION EXTENDS FROM BORDER TO BORDER JUST
NORTH OF OUR CWFA ALONG A PERSISTENT OUTFLOW BOUNDARY FROM
CONVECTION EARLIER THIS MORNING. WEAK CONVECTION OUT AHEAD OF THE
LINE SEEMS TO HAVE SLOWED ITS PROGRESS...BUT STILL EXPECT THE
BOUNDARY TO AT LEAST MAKE IT INTO THE NORTHERN COUNTIES. AIRMASS
SOUTH OF THIS BOUNDARY IS VERY MOIST AND UNSTABLE...MAKING
ADDITIONAL CONVECTION LIKELY ALONG OR NEAR ANY OF THE SEVERAL
BOUNDARIES LAYING ACROSS THE COASTAL BEND AND RIO GRANDE PLAINS.
HEAVY RAINFALL APPEARS TO BE THE MAIN THREAT WITH THIS LINE...AND
SLOW MOVEMENT OF THE LINE COULD LEAD TO LOCALLY EXCESSIVE RAINFALL
WHERE STRONGER CELLS PERSIST.

NO OTHER CHANGES TO GOING FORECAST. SOME CONCERN THAT THE BOUNDARY
CURRENTLY OVER THE EASTERN PART OF THE CWFA EXTENDING OFFSHORE MAY
INHIBIT WIND DEVELOPMENT THIS AFTERNOON...BUT LATEST RADAR RETURNS
SHOW THAT BOUNDARY MAY BE WEAKENING OVER THE WATER...ALLOWING
PREVIOUS FORECAST TO VERIFY ON SCHEDULE.

&&

.PREV DISCUSSION... /ISSUED 355 AM CDT WED JUN 20 2007/

SHORT-TERM (TODAY THROUGH THURSDAY)...ATMOSPHERE IS VERY
MOIST/UNSTABLE WITH LITTLE TO NO CAPPING INVERSION PER LAPS DATA.
LARGE OUTFLOW BOUNDARY OVER THE WESTERN GLFMEX WILL SWEEP ACROSS THE
CWA THIS MORNING AND GENERATE CONVECTION WITH LOCALLY HEAVY RAIN AND
GUSTY WINDS. WILL INDICATE CHANCE TO LIKELY POPS FROM NORTHEAST TO
SOUTHWEST. MASSIVE MCS CURRENTLY ACROSS OKLAHOMA/NORTH TEXAS WILL
LIKELY SEND A STRONG OUTFLOW BOUNDARY SOUTHWARD WHICH WILL
POTENTIALLY AFFECT THE AREA LATER THIS AFTERNOON AND EVENING. THE
ATMOSPHERE WILL HAVE BEEN WORKED OVER FROM MORNING CONVECTION SO
WILL ONLY INDICATE MARGINAL CHANCE POPS. MOIST/UNSTABLE ATMOSPHERE
ESSENTIALLY DOES NOT GO ANYWHERE TONIGHT/THURSDAY AND WILL BE ACTED
UPON BY MESOSCALE BOUNDARIES. WILL SHOW SLIGHT CHANCE POPS TONIGHT
AND MARGINAL LOW-END CHANCE POPS THURSDAY. CLOUDINESS WILL BE RATHER
EXTENSIVE THROUGH THE PERIOD. HAVE FOLLOWED THE COOLER METMOS
TEMPERATURES TODAY BEHIND THE OUTFLOW BOUNDARY. SUSPECT DEWPOINTS
WILL REMAIN HIGHER THAN GUIDANCE TONIGHT/THURSDAY WITH MOIST
GROUND...SO WENT ABOVE GUIDANCE MINS IN MOST INSTANCES TONIGHT.
GENERALLY FOLLOWED THE MAVMOS TEMPERATURES FOR THURSDAY.

AVIATION...MVFR CIGS WILL PREVAIL THIS MORNING WITH SCATTERED TO
NUMEROUS CONVECTION RESULTING IN IFR CIGS/VSBYS. VFR CIGS WILL
PREVAIL THIS AFTERNOON/TONIGHT WITH ISOLATED TO SCATTERED CONVECTION
RESULTING IN LOCALIZED IFR CIGS/VSBYS.

MARINE...SCEC AND PERHAPS MARGINAL SCA CONDITIONS WILL OCCUR ACROSS
ALL THE WATERS TODAY BEHIND THE OUTFLOW BOUNDARY. WINDS WILL
GENERALLY BE BELOW SCEC CRITERIA TONIGHT/THURSDAY. SCATTERED TO
NUMEROUS CONVECTION EXPECTED THIS MORNING WITH OUTFLOW BOUNDARY THEN
MOSTLY ISOLATED CONVECTION THEREAFTER.

LONG TERM (THURSDAY NIGHT THROUGH TUESDAY)...A GRADUAL DRYING TREND
IS STILL EXPECTED TO OCCUR THROUGH THE WEEKEND.  THE LARGE AREA OF
DRY AIR POISED OVER THE CENTRAL GULF WL AFFECT THE CWA THROUGH THE
WEEKEND.  A SLOW-MOVING MID/UPR LOW WL PERSIST ACROSS NORTHEAST
MEXICO THROUGH EARLY NEXT WEEK.  EXPECT MOST OF THE CONVECTION
ASSCTD WITH THIS CLOSED LOW TO REMAIN ON THE MEXICAN SIDE.  STILL
MAY SEE AN ISOLATED STORM WITH AN INCREASE IN CLOUD CVR THROUGH THE
WEEKEND ACROSS THE FAR WEST.  OTHERWISE...WL KEEP THINGS DRY WITH AN
OPTIMISTIC CLOUD CVR FCST.  AN INITIAL SURGE OF HIGHER PWS WL BEGIN
TO AFFECT THE ERN PORTION OF THE CWA ON MON.  BY TUE...THIS SURGE
OF MOISTURE IS EXPECTED TO AFFECT MOST OF THE CWA.  WL GO WITH
SLIGHT CHC TO CHC POPS AREAWIDE FOR TUE.  WL SHOW A SUBTLE WARMING
TREND WITH THE LOWER PWS EARLY IN THR PD AND THEN TREND TEMPS
DOWNWARD AS THE MOISTURE AND CLOUDS INCREASE BY MON AND TUE.
