NWS Austin/San Antonio, TX wrote its last area forecast discussion before the first event at Aug 29, 3:16 AM CST, 4 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE AUSTIN/SAN ANTONIO TX 416 AM CDT FRI AUG 29 2008 .DISCUSSION... UPPER LOW OVER NRN MEXICO WILL CONTINUE TO FUNNEL MOISTURE AND CONVECTION UP THE RIO GRANDE AND PECOS RIVER REGIONS OF SOUTHWEST TX. FLASH FLOODING IS LIKELY THROUGH DAYBREAK OVER PARTS OF VAL VERDE COUNTY WHERE TRAINING THUNDERSTORMS IS OCCURRING. OTHER ACTIVITY IS MORE INTERMITTENT AND LIGHTER BUT STILL CAPABLE OF PRODUCING BRIEF RUNOFF PROBLEMS. WILL HOLD OFF ISSUING A FFA SINCE THIS INCREASE IS LIKELY ASSOCIATED WITH THE LLJ AND SHOULD DECREASE TO A LIGHTER RAIN PATTERN LATE THIS MORNING. THERE DOES REMAIN A SLIGHT POTENTIAL FOR THE EVENT TO REPEAT TONIGHT SO WILL ADDRESS THE LOCALLIZED THREAT IN THE ZONES AND HWO. THE WET PATTERN IS EXPECTED TO BREAK DOWN OVER THE NEXT FEW DAYS SATELLITE WV IMAGERY SHOWS THAT UPPER LEVEL WESTERLIES WILL BRING DRIER AIR INTO NRN MEXICO TO HELP DISPERSE THE TROPICAL TAP FEEDING THE UPPER LOW, AND MODELS SHOW A MID LEVEL RIDGE OVER THE MISSISSIPPI RIVER VALLEY BUILDING OVER TX TO LOWER PRECIPITABLE WATER VALUES TOWARD A MORE SEASONAL 1.5 INCHES BY SUNDAY. WITH THAT COMES RISING MAX TEMPERATURES, BUT A RETURN TO TRIPLE DIGIT HEAT NOT EXPECTED FOR NEXT WEAK JUST YET. THE NEXT CONSIDERATION FOR THE FORECAST IS WHAT TO DO WITH GUSTAV WHICH IS TRENDING FOR A MORE WESTWARD TRACK. THE GFS IS ALREADY PORTRAYING A HOTTER AND DRIER INFLUENCE FOR TUESDAY INTO THURSDAY AND THIS LOOKS REASONABLE FOR TEMPS IN THE MID TO UPPER 90S. MOST MODEL DATA SENDS AT LEAST A PORTION OF GUSTAV OR ITS MOISTURE WESTWARD TOWARD EAST TX LATE IN THE PERIOD WILL AVOID TRIPLE DIGIT TEMPS IN THE EXTENDED FOR NOW. && .PRELIMINARY POINT TEMPS/POPS...
