NWS Corpus Christi, TX wrote its last area forecast discussion before the first event at May 27, 6:05 AM CST, 2 hours 13 minutes earlier.
AREA FORECAST DISCUSSION...UPDATED NATIONAL WEATHER SERVICE CORPUS CHRISTI TX 705 AM CDT WED MAY 27 2009 .DISCUSSION...SEE AVIATION DISCUSSION. NOTE KLRD TERMINAL FORECAST USERS...OBSERVATIONS HAVE JUST BEGUN TO COME IN SO HAVE JUST ISSUED NON-NIL TAF. && .AVIATION...MAIN ISSUE IS TIMING OF CONVECTION SO WILL DEAL WITH THAT FIRST. THUNDER MOST LIKELY AT KVCT AS PROXIMITY OF FRONT TIMING OF SEA-BREEZE MAKES THIS THE MOST LIKELY LOCATION. AT KCRP AND KALI...BELIEVE CONVECTION WILL HAVE TO BE OCCURRING DURING THE LATE MORNING OR EARLY AFTERNOON WITH SEA BREEZE...SO HAVE TEMPOS THERE. AT KLRD...CONVECTION WILL BE LATE...MOST LIKELY INITIATING OVER THE SIERRA MADRE AND MOVING EAST AFTER SUNSET. AFTER 06Z...MUCH UNCERTAINTY REMAINS WITH CONVECTION BUT BELIEVE SUFFICIENT ENOUGH CHANCE FOR ALL BUT KVCT TO WARRANT A PROB30 TSRA. OTHERWISE...MVFR CIGS AND VSBYS AOB MVFR WILL IMPROVE BY 15Z WITH ONLY MVFR CONDITIONS EXPECTED LATER TODAY WITH ANY THUNDERSTORMS. DUE TO LIGHTER WINDS TOWARD MORNING...BELIEVE WE WILL SEE SOME LIGHT FOG AT KVCT AND KALI AFTER 06Z. FINALLY...MVFR CIGS WILL RETURN TO KLRD LATE...UNLESS CONVECTIVE COMPLEX WHICH IF FORMS DELAYS ITS EASTWARD MOVEMENT. AT KLRD THIS MORNING WILL && .PREV DISCUSSION... /ISSUED 507 AM CDT WED MAY 27 2009/ DISCUSSION...DID A QUICK UPDATE FOR FOG THIS MORNING OVER THE NORTHERN AREAS AS VISIBILITIES DOWN TO 1 MILE OR LESS IN SOME LOCATIONS ACCORDING TO OBSERVATIONS. THAT IS IT FOR NOW. PREV DISCUSSION... /ISSUED 326 AM CDT WED MAY 27 2009/ SHORT TERM (TODAY THROUGH THURSDAY)...ANOTHER TRICKY RAIN FORECAST AS TIMING OF RAIN-MAKING MECHANISMS NOT IN PHASE. DYING SECONDARY MCS YESTERDAY MORNING STABILIZED AIRMASS TOO LONG FOR CONVECTION TO DEVELOP LATE IN THE AFTERNOON. FOR TODAY...FRONTAL BOUNDARY AND DAYTIME HEATING WILL PROVIDE MECHANISMS FOR RAIN AS MORE THAN SUFFICIENT MOISTURE AROUND. HOWEVER...S/W SEEN ON WATER VAPOR AND SHOWN BY GFS/NAM (MAINLY NORTH OF CWFA) WILL HAVE ITS EFFECTS MOVE EAST BY MID MORNING...ALLOWING FOR SUBSIDENCE BEHIND THIS. HOWEVER...GIVEN THE AVAILABLE CAPE AND LOWERING CIN DURING THE DAY...BELIEVE THERMALS WILL OVERCOME AFOREMENTIONED SUBSIDENCE... AND INTERACTION OF SEA BREEZE AND FRONT SHOULD ALLOW FOR SUFFICIENT CONVERGENCE FOR CONVECTION. ALSO...ANOTHER WEAK LFQ OF STJ IS PROGGED TO MOVE INTO THE AREA LATE THIS AFTERNOON...SO WILL GENERALLY GO WITH PREVIOUS POP FORECAST WITH MINOR ADJUSTMENTS. MAIN QUESTION TONIGHT IS WHETHER MCS FARTHER WEST DEVELOPS...AND WHETHER DRIER AIR PUSH WILL BE SUFFICIENT TO KEEP MOST OF THE CONVECTION OVER THE SOUTHERN AREAS. GFS AND NAM DISAGREE TOTALLY ON THEIR CONVECTIVE SOLUTIONS...THE FORMER DEVELOPING CONVECTION (AND FEEDBACK...AGAIN) TONIGHT AND NAM BEING MUCH DRIER. ALTHOUGH GFS OVER-DOING THINGS...BELIEVE CONVECTION WILL DEVELOP WEST TONIGHT THEN MOVE EAST OVERNIGHT BEFORE WEAKENING (SIMILAR TO MONDAY NIGHT/TUESDAY MORNING). A BIT DRIER FOR THURSDAY AS FRONT SEEPS A BIT FARTHER SOUTH TO JUST SOUTH OF CWFA BUT STILL ENOUGH MOISTURE AVAILABLE FOR SOME LOW-CHANCE POPS OVER THE SOUTHERN AREAS...THINK DRYING MAY BE SUFFICIENT OVER THE NORTHEAST TO ONLY GO WITH LOW CHANCE POPS. HOWEVER...IF GOOD MCS DEVELOPS OVERNIGHT AND MOVES THROUGH BY THURSDAY MORNING...RAIN DURING THE DAY ON THURSDAY MAY NOT OCCUR TIL LATE AFTERNOON...IF AT ALL. FOR TEMPERATURES...GENERALLY STAYED CLOSER TO GFS-MOS DUE TO UNCERTAINTIES IN FORECAST FOR RAIN...AS THE MORE THE RAIN IS AROUND...THE COOLER IT WILL BE (FRONT WILL NOT COOL THINGS DOWN MUCH BUT WILL BRING MORE CLOUDS AND RAIN POTENTIAL). MARINE (TONIGHT THROUGH THURSDAY)...MODERATE ONSHORE FLOW WILL GRADUALLY BECOME NORTHEAST AS BOUNDARY GRADUALLY MOVES INTO THE WATERS AND SOUTH OF THE CWFA. BEST SHOT OF RAIN TODAY...THEN GRADUALLY DECREASING TONIGHT AND THURSDAY AS DRIER AIR SLOWLY SEEPS IN. SCEC CONDITIONS POSSIBLE TONIGHT NEAR THE COAST. LONG TERM (THURSDAY NIGHT THROUGH TUESDAY)...THE LATEST RUN OF THE GFS IS A BIT MORE AGGRESSIVE WITH DRIER AIR FILTERING IN FROM THE NORTHEAST THURSDAY NIGHT RELATIVE TO PREVIOUS RUNS AND THE CURRENT RUNS OF THE NAM/ECMWF. NEVERTHELESS...THE TREND CONTINUES TO BE FOR THE ATMOSPHERE TO DRY OUT FOR THE WEEKEND. AS A RESULT...TRIMMED POPS FRIDAY BY 10%...BUT MAINTAINED MENTION FOR FRIDAY AFTERNOON AND EVENING CONVECTION ACROSS THE SOUTHERN RIO GRANDE PLAINS WHERE THE DEEPEST MOISTURE WILL RESIDE. TROPOSPHERIC MOISTURE SHOULD REMAIN LIMITED ACROSS SOUTH TEXAS FOR SATURDAY WITH DRY CONDITIONS CONTINUING INTO SUNDAY. NOT REAL CONFIDENT IN THE AGGRESSIVE MOISTURE RETURN THE ECMWF IS ADVERTISING FOR SUNDAY. STILL...LIGHT WINDS AND MARGINAL MOISTURE SHOULD LEAD TO AT LEAST A SLIGHT CHANCE OF CONVECTION LATE SUNDAY AFTERNOON. LOWERED POPS BY 10% BUT MAINTAINED THE MENTION OF AFTERNOON SHOWERS AND THUNDERSTORMS ACROSS THE COASTAL PLAINS FOR SUNDAY AS A RESULT. ZONAL FLOW ALOFT COMBINED WITH INCREASING BOUNDARY LAYER MOISTURE AND WAA SHOULD ALLOW DIURNAL CONVECTION TO DEVELOP DURING BOTH THE MONDAY AND TUESDAY AFTERNOON AND EVENING HOURS. BROAD MID/UPR RIDGING AND ASSOCIATED SYNOPTIC SUBSIDENCE SHOULD OVERSPREAD THE REGION BY THE MIDDLE OF NEXT WEEK WITH DRY CONDITIONS EXPECTED BY WEDNESDAY. && .PRELIMINARY POINT TEMPS/POPS...
