$$What forecasters said that day
The local office's own words before this flash flood warning went out, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.
NWS Austin/San Antonio, TX wrote its last area forecast discussion before this flash flood warning went out at May 27, 3:15 PM CDT, 3 hours 25 minutes earlier.
Area forecast discussion, May 27, 3:15 PM CDT, 3 hours 25 minutes before
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE AUSTIN/SAN ANTONIO TX 315 PM CDT SUN MAY 27 2007 .DISCUSSION... THE SOUTHERN STREAM TROUGH MOVES OUT OF CENTRAL TEXAS MONDAY MORNING AND MERGES WITH THE NORTHERN STREAM FLOW TUESDAY. THE MID LEVEL TROUGH SHIFTS FROM THE CENTRAL HILL COUNTRY TO I-35 AROUND MIDNIGHT TONIGHT AND SHIFTS EAST OUT OF THE COUNTY WARNING AREA MONDAY AFTERNOON. THE CURRENT FLASH FLOOD WATCH GOES UNTIL MIDNIGHT. HOWEVER, SOME COUNTIES MAY NEED TO REMAIN UNDER THE WATCH PAST MIDNIGHT. WILL ALLOW EVENING SHIFT TO MAKE THIS CALL SINCE COMPUTER MODELS HAVE NOT BEEN HANDLING PLACEMENT OF THE MID LEVEL TROUGH AXIS VERY WELL. ONCE THE TROF AXIS SHIFT OUT OF TEXAS, A NORTHWEST FLOW TAKES IT PLACE. THIS WILL LIMIT PRECIPITABLE WATER VALUES TO BELOW SEASONAL LEVELS. WITH A NORTHWEST FLOW ALOFT AND SOUTHEAST FLOW AT LOW LEVELS, MESO-SCALE CONVECTIVE SYSTEMS CAN STILL DEVELOP ON THE DRY LINE AND MOVE SOUTHEAST ACROSS THE HILL COUNTRY AND SOUTH CENTRAL TEXAS TUESDAY THROUGH THURSDAY. MAX TEMPS WILL RETURN TO NORMAL AND SLIGHTLY ABOVE NORMAL LEVELS WITH THE DECREASED PRECIPITABLE WATER. A WEAK WIND SHIFT MAY OCCUR THURSDAY.
