NWS Austin/San Antonio, TX wrote its last area forecast discussion before the first event at May 27, 6:39 AM CST, 21 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE AUSTIN/SAN ANTONIO TX 739 AM CDT SUN MAY 27 2007 .UPDATE... BASED ON THE PAST BEHAVIOR OF THE LATE MORNING MCV IMPACTS ON CONVECTION, HAVE SHORTENED THE VALID TIME OF THE FFA TO 10 AM. THE DAY SHIFT WILL HAVE A COUPLE HOURS TO MONITOR TRENDS TO EVALUATE ANY POTENTIAL FOR FUTURE HEAVY RAINS, BUT THE CURRENT COMPLEX LOOKS ON TRACK TO SWEEP AWAY CONVERGENCE INTO EAST TX FOR SEVERAL HOURS WHILE ANOTHER WEAK CLUSTER OF STORMS NEAR THE RIO GRANDE STAND A POOR CHANCE OF HOLDING TOGETHER AS THEY BECOME INFLUENCED BY THE STABILIZING CONDITIONS TO THE EAST. PRECIPITABLE WATER VALUES NEVER SEEMED TO RECOVER AFTER THE FIRST LARGE MCS MOVED THROUGH THE AREA THU NITE/FRI MORN. RAINFALL TRENDS ONLY BRIEFLY SHOWED EFFICIENT RAINFALL PRODUCTION WITH TRAINING OF CELLS PRODUCING THE SPOTTY OVERNIGHT FLOODING. THE 500 MB TROUGH AXIS IS EXPECTED TO SLIP EAST OF THE ESCARPMENT TODAY, SHIFTING MOST OF THE LIFT NORTH AND EAST OF SOUTH CENTRAL TEXAS. DESPITE CONTINUED HEALTHY RAIN CHANCES, MODEL QPF TRENDS ARE DECREASING, SUGGESTING NO MORE LARGE AND SLOW MOVING MCS ACTIVITY AFTER THIS MORNING. EXPECT CONVECTION FOR THE NEXT COUPLE DAYS TO BE LESS ORGANIZED AND UNABLE TO TAP INTO DEEP SURFACE MOISTURE POOLS. && .PREV DISCUSSION... /ISSUED 645 AM CDT SUN MAY 27 2007/ AVIATION... AREAS OF IFR/MVFR CIGS WILL LIFT TO VFR THIS AFTERNOON, THEN FALL BACK TO MVFR THIS EVENING AND THEN IFR OVERNIGHT. PATCHES OF RA WITH SCT SHRA AND ISOLD TSRA WILL PERSIST THIS MORNING, THEN ISOLD TO SCT SHRA AND TSRA ARE POSSIBLE THIS AFTERNOON THRU TONIGHT. LOCAL IFR/MVFR VSBYS CAN BE EXPECTED IN PRECIP. SELY WINDS AROUND 10 KTS OR LESS WILL PREVAIL. PREV DISCUSSION... /ISSUED 440 AM CDT SUN MAY 27 2007/ DISCUSSION... ESCARPMENT RAIN EVENT IS FINALLY UNFOLDING EARLY THIS MORNING, WITH REDUCED RAIN POTENTIAL STEMMING FROM A SERIES OF MCS TRACKS ACROSS THE COASTAL BEND OVER THE PAST 36 HOURS. THE FEW AREAS THAT SAW 8-10 INCHES OF RAIN THU NITE/FRI MORN COULD SEE ANOTHER 2-4 INCHES OF RAIN, BUT MOST AREAS WILL SEE A 5 DAY TOTAL OF 3-5 INCHES BY THE TIME THE UPPER TROUGH AXIS SHIFTS EAST MONDAY. WHILE THIS MIGHT BE WELCOME NEWS TO THOSE PLANNING HOLIDAY ACTIVITIES NEAR THE WATER, TEMPERATURES WILL CONTINUE TO TOP OUT IN THE 80-85 DEGREE RANGE THE NEXT COUPLE DAYS. ASSUMING THE TROUGH DOESNT RETROGRADE DUE TO WEAK MESOSCALE IMPULSES, AND THE RAINS DO NOT CREATE SIGNIFICANT RIVER RISES THIS MORNING, THE FFA MAY NOT NEED AN EXTENSION PAST TODAY. WILL LET THE WESTERN COUNTIES EXPIRE AT 7 AM AND PLAN A FFA UPDATE TO CONTINUE THE EASTERN COUNTIES THROUGH 7 PM. THE CHANCE FOR HEAVY DOWNPOURS WILL CONTINUE THROUGH MEMORIAL DAY, BUT THE PATTERN DOESNT SUPPORT CELL TRAINING, AND PWAT VALUES SHOULD CONTINUE TO RETREAT BACK TO NORMAL LATER TODAY. MODEL TRENDS SHOW AN INCREASING TREND TOWARD FAIR WEATHER TUE AND WED, BUT A DEEPENING TREND IN A NORTHERN PLAINS TROUGH SIGNALS A COOL FRONT AND A ROUND OF THUNDERSTORMS THURSDAY AND A FEW LINGERING CELLS POSSIBLE IN UNSTABLE FLOW ALOFT FRIDAY. WILL KEEP POPS LOW FOR NOW AS TIMING COULD BE OFF BY UP TO 12 HRS. THE WAKE OF THIS TROUGH WILL BE A HIGH AMPLITUDE RIDGE PROMISING A MORE SEASONAL WARMING TREND FOR THE WEEKEND THE GFS DOES SHOW A WEAK CUT-OFF LOW CAPABLE OF UNDERCUTTING THE RIDGE NEXT SUNDAY, BUT MOST MODELS SHOW THIS DISTURBANCE TO BE WEAK. && .PRELIMINARY POINT TEMPS/POPS...
