NWS Corpus Christi, TX wrote its last area forecast discussion before the first event at Apr 18, 6:05 AM CST, 1 hour 55 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE CORPUS CHRISTI TX 705 AM CDT SUN APR 18 2010 .DISCUSSION...MADE SOME ADJUSTMENTS TO FORECAST TODAY BASED UPON CURRENT TRENDS AND 06Z MODEL GUIDANCE. FRONT HAS REACHED A VCT-ALI LINE. SHOWERS AND THUNDERSTORMS THROUGH THE MORNING WILL REMAIN CONFINED TO THE NORTHERN COASTAL BEND AND GULF WATERS AND PUSH EAST...BASICALLY ALONG AND EAST OF A PORT LAVACA TO PORT ARANSAS LINE WHERE BEST MOISTURE CONVERGENCE AND INFLUENCE FROM APPROACHING UPPER LEVEL SHORTWAVE RESIDES. ALSO LOWERED POPS IN THE AFTERNOON...INTO THE SLIGHT CHANCE AND CHANCE CATEGORY. WEAK SEA-BREEZE STILL MAY TRY TO DEVELOP LATE IN THE AFTERNOON SETTING UP A CHANCE FOR SHOWERS MAINLY ACROSS THE NORTHEAST. UPDATES OUT. && .AVIATION...LINE OF RWS/TSTMS FM PKV-RKP WL CONT TO PUSH OFFSHORE THRU 15Z. WEAK FRONT CURRENTLY RESIDES FM VCT-ALI...AND WL MOVE TO THE COAST OVER THE NEXT FEW HOURS. IFR CIGS WL LAG BEHIND THE FRONT ALI/CRP/VCT THRU 15-16Z...THEN GRADUALLY BCM VFR (POSSB STAY MVFR IN VCT). ADDTL RWS/TSTMS MAY DVLP ALONG AND NE OF I-37 LATER THIS AFTN AS WEAK SEA-BREEZE TRIES TO DVLP. OUT WEST...VFR CONDS COT-LRD. && .PREV DISCUSSION... /ISSUED 425 AM CDT SUN APR 18 2010/ SHORT TERM (TODAY THROUGH TONIGHT)...WEAK COLD FRONT IS LOCATED NEAR A TILDEN TO LAREDO LINE EARLY THIS MORNING. WEAK SOUTHWEST FLOW HAS DEVELOPED AHEAD OF IT ACROSS THE SOUTHERN COASTAL BEND... AND WITH THE WINDS OFF THE GULF NOW FROM THE SOUTH AND SOUTHEAST THE BEST MOISTURE CONVERGENCE STRETCHES FROM PADRE ISLAND UP INTO THE NORTHERN COASTAL BEND AND VICTORIA CROSSROADS. LAST SHORTWAVE DIVING SOUTHEAST THROUGH SOUTH-CENTRAL TEXAS IS ALSO RESULTING IN INCREASING PVA ACROSS THE NORTHEAST CWA. SO HIGHEST POPS THROUGH THE MORNING WILL BE ALONG AND NORTHEAST OF I-37. WEST WINDS DO DEVELOP ALL THE WAY TO THE COAST BY MIDDAY...BUT THEN WEAKEN AND POSSIBLY TURN BACK TO THE SOUTH AND SOUTHEAST LATE AFTERNOON ACROSS THE COASTAL COUNTIES AND NEARSHORE WATERS AS A SEA-BREEZE TRIES TO DEVELOP. AS THIS HAPPENS THERE STILL MAY BE ENOUGH JUST ENOUGH MOISTURE AND LOW LEVEL CONVERGENCE ACROSS THE NORTHEAST CWA TO MAINTAIN A CHANCE FOR SHOWERS INTO THE AFTERNOON AND EARLY EVENING. FRONT DOES CLEAR THE COAST TONIGHT WITH DRIER AIR AND NORTHWEST TO NORTH FLOW DEVELOPING. DECIDED TO CANCEL THE FLASH FLOOD WATCH. STILL HAVE LEFT MENTION OF LOCALLY HEAVY RAINFALL IN THE FORECAST...BUT THREAT FOR WIDESPREAD FLASH FLOODING DOES NOT SEEM LIKELY. LONG TERM (MONDAY THROUGH SATURDAY)...MAY FINALLY SEE SOME QUIET WEATHER FOR A CHANGE...BUT THERE WILL BE WEATHER IN BETWEEN THE QUIET PERIODS. OVERALL...MODELS REMAIN IN STATUS QUO THROUGH FRIDAY WITH DRY WEATHER EXPECTED ON MONDAY AND WEDNESDAY. RAIN BEGINNING AGAIN OUT WEST MONDAY NIGHT AND MOVING INTO REMAINING AREAS OVERNIGHT AND CONTINUING THROUGH TUESDAY AS NEXT UPPER WAVE COMES ACROSS. INSTABILITY RATHER LIMITED SO WILL LIKELY SEE ONLY SHOWERS BUT DID MENTION THUNDER FOR THE AFTERNOON. MOST OF THE RAIN SHOULD BE EAST OF THE AREA BY TUESDAY NIGHT...MAYBE SOME LEFT-OVER ACTIVITY IN THE GULF AT BEST...THEN ANOTHER RIDGE TEMPORARILY KEEPS THINGS DRY. NEXT UPPER TROUGH COMES ACROSS LATE THURSDAY AND CONTINUES INTO FRIDAY MORNING...THEN SOME DRYING FROM SOUTHWEST TO NORTHEAST POSSIBLE FOR FRIDAY AFTERNOON. MODELS THEN DIVERGE SOME ON UPPER PATTERN...WITH ECMWF KEEPING TROUGHS COMING WHILE GFS IS MORE BENIGN. ECMWF ALSO KEEPING SUFFICIENT MOISTURE OVER THE NORTHEAST ON SATURDAY. SINCE EXTENDED CANADIAN (ON WEB) SHOWING TROUGH OUT TO THE WEST AS WELL ON SATURDAY...WILL MENTION A SLIGHT CHANCE FOR CONVECTION OVER THE NORTHEAST FOR SATURDAY. MODEL CONSENSUS IS NOW FOR NORTHERLY SURFACE FLOW THROUGH TUESDAY AFTERNOON...WITH RAIN COOLED AIR TO THE NORTH WILL LOWER MIN TEMPS MONDAY NIGHT AND TUESDAY. WARM UP AFTER THAT AND COULD SEE SOME 90S AGAIN OUT WEST FRIDAY AND SATURDAY IF DRIER AND WARMER BOUNDARY LAYER AIR DOES PUSH IN. SOME DIFFERENCES BETWEEN ECMWF AND GFS ON SURFACE FRONT FRIDAY NIGHT/SATURDAY. WILL LEAN MORE TOWARD THE GFS COOLER SOLUTION...BUT NOT BUY IT WHOLE HEARTEDLY YET WITH UPPER TROUGH POSSIBLY REMAINING WEST ALTHOUGH DRIER AIR OVERALL WILL MEAN SLIGHTLY COOLER TEMPERATURES FOR LOWS ANYWAY. && .PRELIMINARY POINT TEMPS/POPS...

RAINFALL AMOUNTS ARE NOT EXPECTED TO PRODUCE SIGNIFICANT FLOODING AT THIS TIME...AS ATMOSPHERIC MOISTURE WILL BE LOWER AND UPPER LEVEL FLOW WILL MOVE THE STORMS SUFFICIENTLY TO PRECLUDE EXCESSIVE RAINFALL THAT NORMALLY RESULT FROM NEARLY STATIONARY STORMS. .SPOTTER INFORMATION STATEMENT...
