AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE AUSTIN/SAN ANTONIO TX 300 PM CDT MON SEP 11 2006 .DISCUSSION... WET AND RAINY DAY ACROSS SOUTH CENTRAL TEXAS AS MOISTURE SPREAD NORTH OUT OF SOUTH TEXAS, AND FRONTAL BOUNDARY DRIFTED SOUTH INTO THE HILL COUNTRY. WILL CONTINUE TO SEE MORE RAIN ACROSS THE CWA TONIGHT AND TOMORROW AS THE WEAK COLD FRONT CONTINUES TO PROGRESS SOUTHWARD. GIVEN THE MOIST TROPICAL AIRMASS SITTING OVER THE REGION, WILL LIKELY SEE WIDESPREAD RAINFALL TOTALS OF AT LEAST HALF OF AN INCH BEFORE TOMORROW NIGHT. LOCALLY HIGHER AMOUNTS UP TO 3 INCHES WILL BE POSSIBLE, AND COULD CAUSE PROBLEMS FOR LOW- LYING AND URBAN AREAS. WIDESPREAD FLOODING DOES NOT LOOK LIKE AN ISSUE AT THIS POINT, AS MOST AREAS ACROSS THE CWA ARE STILL UNDER EXTREME DROUGHT CONDITIONS. WEDNESDAY AND THURSDAY LOOK TO BE DRIER AS THE FRONT PUSHES SOUTH OUT OF OUR AREA. TEMPERATURES BEHIND THE FRONT WILL BE A FEW DEGREES BELOW MID-SEPTEMBER NORMALS, WITH MUCH OF SOUTH CENTRAL TEXAS DIPPING INTO THE LOWER TO MID 60S BY THURSDAY MORNING. TEMPERATURES WILL GRADUALLY WARM UP OVER THE WEEKEND AS SOUTHWEST FLOW ALOFT BRINGS A RETURN OF PACIFIC MOISTURE TO THE REGION. STILL NO GOOD CONSENSUS WITH MODEL GUIDANCE ABOUT THE CHANCE OF RAIN OVER THE WEEKEND AND INTO EARLY NEXT WEEK. FOR NOW, WENT WITH SLIGHT TO LOW-END CHC POPS, MAINLY ALONG AND SOUTH OF THE I-35 CORRIDOR. && .PRELIMINARY POINT TEMPS/POPS...
