NWS Austin/San Antonio, TX wrote its last area forecast discussion before the first event at May 26, 5:51 AM CST, 39 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE AUSTIN/SAN ANTONIO TX 651 AM CDT SAT MAY 26 2007 .AVIATION... THIS MORNING, A BAND OF SHRA/TSRA WILL PERSIST ALONG A VCT TO 3T5 TO TPL LINE SHIFTING SLOWLY EAST, SCATTERED SHRA/TSRA WILL MOVE EAST FROM THE EAGLE PASS AREA TO COT AND PEZ, WITH ISOLATED SHRA ELSEWHERE. THIS AFTERNOON THROUGH TONIGHT, GOOD CHANCES OF SHRA/TSRA WILL CONTINUE. AREAS OF IFR/MVFR CIGS WILL LIFT TO VFR THIS AFTERNOON, THEN LOWER TO MVFR THIS EVENING AND IFR LATER TONIGHT. SELY WINDS LESS THAN 10 KTS WILL PREVAIL. && .PREV DISCUSSION... /ISSUED 448 AM CDT SAT MAY 26 2007/ DISCUSSION... OVERNIGHT DESTABILIZATION HAS BEEN GRADUAL THIS MORNING AS PRECIPITABLE WATER VALUES TEMPORARILY FELL BELOW 1.5 INCHES ACROSS MUCH OF THE CENTRAL AND WESTERN COUNTIES. THIS DROP SEEMS TO HAVE IMPACTED MODEL OUTPUT FROM THE 00Z RUNS WITH LOWER POPS AND QPF. HOWEVER, THE ENVIRONMENT WILL LIKELY RECOVER WITH PRECIPITABLE WATER VALUES REBOUNDING BACK TO ABOVE 2 STANDARD DEVIATIONS ABOVE AREA NORMS. THE MID AND UPPER LEVEL PATTERNS FOR THE NEXT 2 DAYS STILL SHOWS A FAVORABLE ENVIRONMENT FOR MOISTURE CONVERGENCE, WITH A MID LEVEL LOW OVER CENTRAL TX AND THE BROAD AND SHALLOW UPPER TROUGH STILL APPROACHING FROM THE SW. WHILE, THE MODEL TRENDS SUGGEST THE QPF AMOUNTS PREDICTED PREVIOUSLY MAY BE A TAD STRONG, THE THREAT FOR LIFE THREATENING FLASH FLOODS CONTINUES THIS WEEKEND. THE NEXT WAVE OF RAIN IS GETTING UNDERWAY AT 4 AM, WITH A WEAK COMPLEX MOVING OVER THE RIO GRANDE. HIGHER PRECIPITABLE WATER VALUES REMAIN OVER EASTERN COUNTIES WHERE A NORTH-SOUTH PATTERN OF TRAINING THUNDERSTORMS HAS BECOME MORE PRONOUNCED OVER THE PAST FEW HOURS. THESE TWO AREAS OF HEAVIER RAINS FROM THE WEST AND THE EAST APPEAR TO BE FILLING IN WITH MODERATE SHOWERS AND COULD EVOLVE INTO NUMEROUS THUNDERSTORMS OVER THE ESCARPMENT COUNTIES BY DAYBREAK. MORNING RAINFALL RATES COULD BE A BIT LIGHTER DUE TO THE TEMPORARY LOWERING OF AVAILABLE MOISTURE. HOWEVER, THE SFC TO 850 MB FLOW WAS SHOWN IN VAD WIND TRENDS TO BE INCREASING SOUTHERLY, SO THE MOISTURE TRANSPORT COULD SUPPORT HEAVIER RATES BY LATE THIS MORNING. THE HEAVIER RATES OF 2-3 INCHES PER HOUR ARE ALREADY OCCURRING NEAR A WEAK MCV OVER MAVERICK COUNTY. DUE TO THE LOCATION OF THE DEVELOPING RAINS BEING MOSTLY SOUTH AND EAST OF THE ESCARPMENT AND THE MOSTLY MODERATE RATES, THE THREAT TO SOME HILL COUNTRY RIVERS MAY NOT DEVELOP UNTIL LATER IN THE DAY. MUCH OF WHAT HAPPENS THIS AFTERNOON COULD HINGE UPON THE FATE OF THE WEAKENING MCS OVER THE RIO GRANDE THIS MORNING A RESURGENCE OF THE COMPLEX OVER THE RIO GRANDE PLAINS/COASTAL BEND COULD CUT OFF MOISTURE TRANSPORT INTO THE HILL COUNTRY AND FOCUS ALL THE HEAVY RAINS TO THE SOUTH. THESE MESOSCALE UNCERTAINTIES WILL MAKE DETAILS DIFFICULT OUTSIDE OF 6-12 HOURS DURING THIS HOLIDAY WEEKEND RAIN EVENT. THUS THE FFA WILL CONTINUE, AND AN EXTENSION WILL BE ISSUED LATER THIS MORNING TO EXTEND THE WATCH INTO SUNDAY MORNING. MODEL TRENDS SHOW A SLIGHTLY MORE PROGRESSIVE PATTERN ALOFT BY MONDAY, SO THE GFS FOCUS OF HIGHER POPS TO THE EAST MON-WED WERE AGREEABLE. TRENDS FOR LATE IN THE WEEK CONTINUE TO SHOW A DRYING TREND LATE NEXT WEEK. PERHAPS THEN, SAT WILL SEE THE 1ST 90 DEGREE DAY IN OVER 6 MONTHS. && .PRELIMINARY POINT TEMPS/POPS...
