NWS Brownsville, TX wrote its last area forecast discussion before the first event at Sep 3, 2:00 PM CST, 4 hours 11 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE BROWNSVILLE TX 300 PM CDT FRI SEP 03 2004 .SHORT TERM...OVER THE WESTERN PORTION OF THE CONUS AREA...TWO 5H FEATURES WILL BE THE MAJOR PLAYERS. THE FIRST IS A STRONG 5H SHORT WAVE PROGGED TO DIG DOWN ACROSS THE ROCKIES AND EVENTUALLY MOVING OUT INTO THE CENTRAL U.S. BY THE 60 HR MARK. MEANWHILE...FURTHER SOUTH...A QUASI-STATIONARY SHORT WAVE REMAINS ANCHORED IN PLACE OVER THE TX COASTLINE PRODUCING THE RECENT CONV. THE ETA AND GFS DIFFER A BIT ON THE EVENTUAL RESOLUTION OF THE SHORT WAVE OVER THE TX COASTLINE...BUT THE OVERALL TREND IS FOR THIS FEATURE TO BE GRADUALLY PUSHED SOUTHWARDS AS THE 5H RIDGE STARTS REBUILDING OVER THE TX/MEX BORDER REGION. AS A RESULT OF THIS GRADUAL DISSIPATION OF THE SHORT WAVE OVER TX COASTLINE...BOTH THE ETA AND THE GFS GRADUALLY DROP OFF THE OVER POPS AROUND THE REGION...BUT MAINTAIN SOME ISOLD CONV FOR THE UPCOMING LABOR DAY WEEKEND. SO WILL REFLECT THIS TREND IN THE CURRENT ZFP PACKAGE WITH ONLY SOME MINOR ADJUSTMENTS NEEDED TO THE OVERALL ALIGNMENT. SOME DECENT CONVECTION HAS FIRED UP JUST SOUTH OF THE RIO GRANDE RIVER AND IS MOVING NORTHWARDS TOWARDS THE WESTERN PORTIONS OF THE BRO CWA. AFTERNOON HEATING IS HELPING GENERATE THIS ACTIVITY WHICH SHOULD LINGER INTO THE EARLY EVENING. THE SOIL MOISTURE LEVELS HAVE INCREASED SOMEWHAT WITH THE RECENT CONV AND THESE STORMS TO THE SOUTH MAY MEET OR EXCEED THE RAINFALL RATES NEEDED FOR FLASH FLOODING. SO WILL POST AN FFA FOR ZAPATA...STARR...HIDALGO AND JIM HOGG COUNTIES INTO THE EARLY EVENING. MAV AND MET FORECAST TEMPS ARE IN PRETTY GOOD AGREEMENT FOR THE WEEKEND AS THE DECREASING CLD COVER AND POPS WILL ALLOW AFTERNOON HIGH TEMPS TO REBOUND A LITTLE. THEREFORE...WILL NOT DEVIATE TOO MUCH FROM NUMERICAL TEMP GUIDANCE. && .LONG TERM...GFS AND ECMWF GUIDANCE BOTH INDICATE THE 5H RIDGING REBUILDING OVER THE SOUTH CENTRAL PLAINS STATES AND THE BORDER REGION AFTER THE 60 HR MARK. ACCORDINGLY...WITH THE INCREASING SUBSIDENCE FLOW...MOISTURE LEVELS WILL DROP OFF STEADILY THROUGHOUT THE UPCOMING EXTENDED PERIOD. WITH THE RESIDUAL MOISTURE STUBBORNLY HOLDING ON AND DAYTIME HEATING BECOMING MORE PROMINENT...BELIEVE THAT ANY CONV WILL BE MORE DRIVEN BY SEA BREEZE ACTIVITY AND AFTERNOON HEATING NEXT WEEK AND WILL WORD THIS ACCORDINGLY IN THE LONGER RANGE PERIOD. WITH THE INCREASED 5H RIDGING EXPECTED OVER THE REGION...HIGH TEMPS WILL GO ABOVE CLIMO ONCE AGAIN. TWO SURFACE FEATURES WILL POTENTIALLY AFFECT THE TX COASTLINE LATE NEXT WEEK. THE FIRST IS A STRONG 5H SHORT WAVE AND ACCOMPANING STRONG SURFACE FRONT WHICH IS PROGGED TO PUSH TOWARDS THE GULF COAST LATE NEXT FRI/EARLY SAT. MEANWHILE...GFS IS MOVING WHAT IS CURRENTLY T.S. IVAN INTO THE EASTERN GULF OF MEX BY NEXT SUNDAY. AS ALWAYS... RESIDENTS ALONG THE LOWER TEXAS GULF COAST WILL NEED TO CLOSELY MONITOR THE PROGRESS OF IVAN AND CONTINUE TO MONITOR THE LATEST STATMENTS AND FORECAST FROM TPC. && .MARINE...AT 18Z...BUOY020 REPORTED NORTH WINDS AT 6 KTS AND SEAS AT 2 FEET. COASTAL TROUGHING DRIFTED NORTH. ISOLATED SHOWERS AND THUNDERSTORMS REMAIN THROUGH THE FORECAST AS AN UPPER LEVEL DISTURBANCE REMAINS TO THE WEST. WINDS AND SEAS WILL BE HIGHER IN AND NEAR ANY CONVECTION. THE UPPER LEVEL DISTURBANCE COMBINED WITH A WEAK SFC PGF WILL RESULT IN LIGHT WINDS AND LOW SEAS WITH A SLIGHT CHANCE OF SHOWERS AND THUNDERSTORMS THROUGH EARLY NEXT WEEK. BY TUESDAY A WEAK COLD FRONT APPROACHES THE COASTAL BEND PRODUCING A SLIGHT INCREASE IN SEAS. && .AVIATION...RGV REMAINS PREDOMINANTLY VFR WITH A FEW PATCHES OF MVFR CIGS MOVING ACROSS THE REGIONAL AIRPORTS. EXPECT PREDOMINANTLY VFR CONDITIONS WITH TEMPO MVFR TO IFR CIG AND VIS DUE TO SCT TSTMS AND PATCHY OVERNIGHT FOG. PRECIP CHANCES DECREASE THROUGH THE WEEKEND AS AN UPPER LEVEL DISTURBANCE MIGRATES EAST. && .PRELIMINARY POINT TEMPS/POPS...
