SOUTH TEXAS FORECAST DISCUSSION NATIONAL WEATHER SERVICE CORPUS CHRISTI TX 427 AM CDT FRI SEP 19 2003 SHORT TERM (TODAY THROUGH SATURDAY)...SURFACE PLOTS DURING THE LAST 12 HOURS INDICATE THAT FRONT BECAME VERY DIFFUSE AS DRIER AIR ROLLED DOWN THE ESCARPMENT. SURFACE MESONET OBSERVATIONS AND HIGH RES RADAR IMAGERY DEPICTS A BOUNDARY WHICH PROBABLY QUALIFIES AS THE COOL FRONT HAS STALLED JUST OFFSHORE AND IS DRAPED THROUGH BAFFIN BAY SW TO FALCON LAKE. WINDS ARE NORTHERLY BEHIND THIS FEATURE AND DEWPOINTS CONTINUE TO FALL INTO THE MID 60S. GOES SOUNDER DEPICTS MUCH DRIER AIR IS CURRENTLY MOVING IN FROM THE NORTH AND ALL MODEL SOLUTIONS DISTINCTLY SHOW A DECREASE IN LOW LEVEL THETA E AND PWAT FROM NE TO SW DURING THE DAY TODAY. HAVE DECIDED TO UNDERCUT GUIDANCE POPS AS THE INFLUX OF DRIER AIR WILL MAKE IT TOUGH FOR CONVECTION TO GET GOING...ESPECIALLY OVER THE NORTH WHERE EVEN SOME SUNSHINE IS EXPECTED. MODELS ARE IN UNANIMOUS AGREEMENT IN ANOTHER LARGE CONVECTIVE EPISODE JUST SOUTH OF THE CWA TODAY. DUE TO SATURATED SOILS...GOOD LOW LEVEL JET CONTINUING AND UPPER LEVEL DIVERGENCE...FEEL THAT THE FLASH FLOOD WATCH WILL NEED TO BE CONTINUED FOR THE COASTAL COUNTIES AND THE SOUTHERN INTERIOR COUNTIES WHERE MOISTURE WILL BE BEST. STALLED BOUNDARY WILL EVOLVE INTO THE INFAMOUS COASTAL TROUGH THIS EVENING AND WILL CONTINUE SOME CHANCE POPS OVER THE SOUTH WHERE MOISTURE WILL REMAIN MORE THAN ADEQUATE. BY SATURDAY...ONCE AGAIN MODELS ARE IN EXCELLENT AGREEMENT THAT A STRONG JET STREAK POSITIONED TO THE NORTH WILL AID IN UPWARD FORCING JUST AS THE LOW LEVEL JET BECOMES MORE SE TO NW ORIENTED AND ALLOWS DEEP TROPICAL MOISTURE TO ADVECT BACK. HPC QPF INDICATES 3-5 OF RAIN WILL BE POSSIBLE THROUGH SAT OVER THE SE CWA. CURRENT FLOOD EVENT HAS STRIKING SIMILARITIES TO THE OCT 1997 EVENT WHICH PRODUCED OVER 20 INCHES OF RAIN IN EASTERN NUECES COUNTY IN 3-4 DAYS. BARRING ANY MESOSCALE WIND EVENTS...WINDS SHOULD REMAIN NEAR 15KTS OFFSHORE AND NO ADVISORIES EXPECTED. LONG TERM (SATURDAY NIGHT THRU THURSDAY)...WET WEATHER PATTERN WILL PERSIST INTO SUNDAY AS ABUNDANT MOISTURE AND CONSISTENT UPPER LEVEL JET STREAK STAYS OVER THE REGION. STRONGER LOW LEVEL MOISTURE CONVERGENCE/LIFT WILL BE OVER THE SOUTHERN PORTION OF THE RIO GRANDE PLAINS SATURDAY EVENING. FOCUS FOR MORE CONVECTION WILL REDEVELOP NEAR THE COASTAL TROUGH EARLY SUNDAY MORNING FOR THE SOUTHERN PART OF THE COASTAL BEND. DYNAMICS FROM THE UPPER LEVEL JET STREAK DO NOT APPEAR TO BE AS STRONG ON SUNDAY AS SATURDAY SO WILL NOT GO LIKELY POPS...HIGH CHANCE POPS THE SOUTHERN COASTAL BEND NEAR THE COASTAL TROUGH. MODELS ARE CONTINUING TO BACK OFF FROM THE STRENGTH OF THE NEXT UPPER TROUGH AND THEREFORE PASSAGE OF COLD FRONT ON MONDAY. WILL SLOW DOWN THE TIMING OF THE FRONT TIL LATE AFTERNOON/EVENING. WITH MODELS NOT HAVING A HANDLE ON WHEN MOISTURE WILL FINALLY LEAVE THE AREA AND LACK OF PUSH FROM COLD FRONT...WILL CONTINUE CHANCE POPS FOR MONDAY. THERE ARE DIFFERENCES BETWEEN THE ETA AND GFS WITH THE POSITION OF THE COASTAL TROUGH...THE ETA MOVES IT INTO THE RIO GRANDE PLAINS WHILE THE GFS SHIFTS IT FARTHER EAST INTO THE GULF OF MEXICO WITH DRIER AIR MOVING IN DUE TO NORTHEAST LOW LEVEL FLOW. NOT VERY CONFIDENT WITH MODELS PAST 48 HOURS ESPECIALLY WITH MOISTURE FIELDS. HESITANT TO MAINTAIN DRY FORECAST FOR TUESDAY IN LIGHT OF THE FACT THE ECMWF MODEL KEEPS A HINT OF THE COASTAL TROUGH NEARBY. WILL NOT CHANGE THE LATER PERIODS OF THE FORECAST IN HOPES THAT MEDIUM RANGE MODELS GAIN SOME CONSISTENCY.
