Area forecast discussion, Oct 20, 2:40 PM CDT, 5 hours 17 minutes before
COASTAL BEND FORECAST DISCUSSION NATIONAL WEATHER SERVICE CORPUS CHRISTI TX 240 PM CDT TUE OCT 20 1998 ALL THE MODELS ARE IN FAIR AGREEMENT IN SLOWLY DRYING US OUT THROUGH THIS UPCOMING FCST PD. THE QUASI-STATIONARY FNT LOCATED IN THE COASTAL WATERS WL BE PUSHED SWD ON WED AS ANOTHER COLD FNT SWINGS THROUGH THE CWA BY WED NIGHT. MEANWHILE AN IMPRESSIVE AREA OF LOW PRESSURE IN THE BAY OF CAMPECHE WL LKLY CONTINUE TO SLOWLY DEVELOP AS IT SLOWS DOWN ITS WWD MOTION. THE CURRENT THINKING IS THAT THE MAIN EFFECT FROM ALL OF THIS WL BE TO INCREASE THE PRESSURE GRADIENT AND CAA ESPECIALLY ACROSS THE COASTAL WATERS. THUS WE MAY NEED A SMALL CRAFT ADVY BY WED AFTN AS WINDS AND SEAS CONTINUE TO BUILD. THINK MOST OF THE CONVECTION FROM THIS AREA OF LOW PRESSURE COMBINED WITH THE OFFSHORE FNT WL REMAIN CONFINED TO THE OFFSHORE WATERS...HOWEVER I CANNOT RULE OUT SOME SHRAS/TSRAS MAKING IT TO THE SRN COASTAL AREAS. EITHER WAY I WL BE GOING WITH SLIGHT CHC OR CHC POPS THROUGH WED FOR THE ENTIRE CWA GIVEN THE MOIST AIRMASS. MODERATE NLY/NELY LOW LVL FLOW WL CONTINUE WED NIGHT INTO THU. DURING THIS PD...THE MID/UPR LVL FLOW BECOMES NLY AS WELL. THUS THE DRYING OUT PROCESS WL BE QUITE GOOD. THE CAA WL ALSO CONTINUE AS WELL. WE MAY SEE A FEW SHRAS/SPRINKLES EARLY WED EVE BUT RIGHT NOW I AM LEANING TWDS NO POPS FOR WED NIGHT. WE WL BE TOO DRY ON THU SO NO POPS WL BE NEEDED. HAVE TRENDED TWDS THE WARMER NGM MOS FOR TNT AND SHAVED A FEW DEGS FOR WED NIGHT. HOWEVER THE NGM MOS IS WAY TOO WARM FOR ITS FCST HIGHS. THUS THE COOLER FAN HIGHS ARE FAVORED. PRELIMS FOLLOW...
