SOUTH TEXAS FORECAST DISCUSSION NATIONAL WEATHER SERVICE CORPUS CHRISTI TX 245 AM CDT TUE SEP 23 2003 SHORT TERM (TODAY THROUGH WEDNESDAY)...BASICALLY A TEMPERATURE FORECAST IN THE SHORT TERM. ACTUAL HIGH TEMPS HAVE BEEN SIGNIFICANTLY LOWER THAN ALL MODEL GUIDANCE. ALTHOUGH GFS HAS BEEN THE CLOSEST AND THE ETA MOS COMPLETELY OUT TO LUNCH. BELIEVE THIS TREND WILL CONTINUE AS SATURATED GROUND CONDITIONS COUPLED WITH LITTLE AIRMASS CHANGE AND HIGH CLOUDINESS WILL KEEP TEMPS ABOUT THE SAME. WILL TREND SLIGHTLY WARMER THAN YESTERDAY CONSIDERING THE LOW-MID LVLS WILL BE DRIER THAN PAST COUPLE DAYS. THE NERN COUNTIES SHOULD BE THE WARMEST WHERE CLOUDS WILL BE THINNEST. WILL SIGNIFICANTLY UNDERCUT GUIDANCE OUT WEST WHERE MOISTURE IS DEEPER. PATCHY DENSE FOG IS ANTICIPATED ACROSS THE COASTAL PLAINS IN THE NEXT FEW HOURS WHICH WILL BURN OFF AROUND 9AM. FOG POTENTIAL WILL BE ABOUT THE SAME TUE NGT WITH LIGHT SE WINDS AND DRY AIR IN THE LOW-MID LVLS. LONG TERM (WED NIGHT THRU MON)...UPR LVL ANTICYCLONE OVER THE WRN GOMEX WILL SHIFT WEST AS A STRONG S/WV PUSHES THROUGH THE GREAT LAKES. AS THIS OCCURS...THE UPR FLOW WILL BECOME WNW CONTINUING TO TRANSPORT MID AND HIGH LVL MOISTURE FROM MARTY EAST INTO THE REGION. MODELS ALSO SHOW A S/WV IN THE MID LVL FLOW APPROACHING THU-FRI. THE ORIGINS OF THE S/WV APPEAR TO BE FROM MARTY BEING ABSORBED OUT WEST. ONSHORE FLOW WILL RESUME BY WED NIGHT AS SFC HIGH PRESSURE SHIFTS EAST. A WEAK COLD FRONT WILL APPROACH THE REGION ON THU... STALLING ACROSS THE AREA FRI AS THE AFOREMENTIONED S/WV QUICKLY LIFTS INTO THE NERN STATES. MOISTURE FIELDS CONTINUE TO BE AN AREA OF LARGE DISAGREEMENT AMONGST THE DIFFERENT MODELS AS THE ETA REMAINS VERY DRY WHILE THE UKMET AND CANADIAN ARE RATHER MOIST WITH THE GFS SOMEWHERE IN BETWEEN. THINK WHAT WILL LIKELY HAPPEN IS MOISTURE WILL RETURN UP THE RIO GRANDE AND THERE WILL BE A LARGE E-W MOISTURE GRADIENT IN PLACE LATE THIS WEEK. THIS REMAINS RATHER UNCERTAIN AND WILL CONTINUE W/ SLT CHC POPS ALL ZONES THU AND FRI...ALTHOUGH IF CANADIAN AND UKMET SOLN VERIFY MAY NEED TO BUMP UP TO CHC POPS...ESP IN WRN ZONES. GFS...CANADIAN AND ECMWF IN GOOD AGREEMENT THAT REINFORCING S/WVS WILL EVENTUALLY CARVE OUT A DEEP UPR TROF ACROSS THE UPR MS RIVER VALLEY WHILE HIGH PRESSURE RIDGES UP THE WRN US. HOWEVER...THE GFS HAS BACKED OFF PREVIOUS RUNS WRT SOUTHWARD MOVEMENT OF THE ASSOC COLD FRONT (A RE-OCCURRING THEME THIS WEEK). PREVIOUSLY THE GFS SHOWED A FROPA ON SUN BUT NOW THE MODEL SHOWS THE FRONT ARRIVING ON MON AS IT WAITS FOR A FINAL STRONGER REINFORCING S/WV TO PUSH THE BOUNDARY FURTHER SOUTH. WILL CONTINUE TO PUT VERY LITTLE FAITH IN MODEL PREDICTIONS THAT SHOW STRONG FRONTS MAKING TO SOUTH TEXAS IN SEPTEMBER...ONLY TO PUSH BACK THE TIMING A DAY AT A TIME WITH EACH NEW RUN. WE WILL SEE A STRONG FRONT MAKE IT TO THE REGION...BUT MY BET IS ON OCTOBER FOR NOW.
