What happened

The episode as NWS EWX wrote it up.

Most of South Central Texas received significant rainfall during the month and only Edwards, Karnes, Kerr, and Val Verde Counties remained in severe drought category (Stage D2) at the end of the month. While much of South Central Texas measured five to eight inches of rain during the month, these four counties generally had less than three inches. Fire danger was low to moderate and Edwards, Karnes, and Val Verde counties had burn bans in effect. The Texas Crop and Weather Report issued by Texas A & M Agricultural reported that cattle still needed supplemental feed and hay. Area lakes and reservoirs continued below normal pool elevations. Lake Travis was around 46 feet below normal and Medina Lake 64 feet below. The seven day stream flow average across the Lower Colorado and Rio Grande River basins was below normal.

DISCUSSION...
CONTINUED TRENDS WITH ONGOING FORECASTS. WEAKNESS IN THE HEIGHT
FIELD FROM 700 TO 300 HPA ACROSS SOUTH CENTRAL TEXAS IS FORECAST
TO MOVE WEST TO THE BIG BEND AREA SATURDAY NIGHT AND SUNDAY AND
WEAKEN. CONTINUED TREND OF ISOLATED TO SCATTERED SHOWERS OR
THUNDERSTORMS FOR SATURDAY THROUGH SATURDAY EVENING. SOME OF
THESE THUNDERSTORMS COULD PRODUCE STRONG WINDS GUSTS OF 30 TO
40 MPH ACROSS PARTS OF SOUTH CENTRAL TEXAS LATE SATURDAY
AFTERNOON TO THE EARLY EVENING ON SATURDAY. THE POTENTIAL
FOR STRONG OUTFLOW WINDS FROM ISOLATED TO SCATTERED THUNDERSTORMS
WILL BE GREATEST EAST OF A LINE FROM LLANO TO HONDO TO DILLEY.

RIDGING FROM 500 TO 300 HPA IS FORECAST TO INCREASE ACROSS THE
SOUTH CENTRAL TEXAS FROM THE NORTH ON SUNDAY AND MONDAY...AND STAY
OVER THE AREA TUESDAY THROUGH THURSDAY. CONTINUED THE TREND OF
ISOLATED SHOWERS OVER THE EAST TO SOUTHEAST PART OF SOUTH CENTRAL
TEXAS SUNDAY. DRY WEATHER IS EXPECTED MONDAY THROUGH WEDNESDAY
AND THURSDAY OF NEXT WEEK...WITH HOT AFTERNOONS FOR AN EARLY
SEPTEMBER SETTING.

THE STORM TRACK TO THE NORTH IS STILL FORECAST TO MOVE SOUTH IN
THE MID TO LATE PART OF NEXT WEEK...BRINGING A DISTURBANCE AND
ITS ASSOCIATED COLD FRONT ACROSS SOUTH CENTRAL TEXAS FROM THE
NORTHWEST ON THE WEEKEND OF SEP. 8TH AND 9TH. THIS WILL BRING A
CHANCE OF SHOWERS TO THE AREA LATE IN THE WEEK AND NEXT WEEKEND
TO POSSIBLY MONDAY OF THE FOLLOWING WEEK OF SEP 9TH TO SEP 15TH.

.PREV DISCUSSION... /ISSUED 344 PM CDT FRI AUG 31 2012/

DISCUSSION...
ISOLATED TO SCATTERED SHOWERS AND THUNDERSTORMS HAVE DEVELOPED IN
AN INCREASINGLY MOIST AIRMASS CREATED BY TROPICAL DEPRESSION ISAAC
MOVING NORTH ACROSS MISSOURI AND A WEAK EASTERLY WAVE MOVING WEST
FROM THE GULF OF MEXICO AS WELL AS CONVECTIVE TEMPERATURES BEING
REACHED. THE SHOWERS AND THUNDERSTORMS WILL PERSIST INTO THIS
EVENING AND RAPIDLY DISSIPATE AROUND SUNSET WITH LOSS OF HEATING.
THE EASTERLY WAVE MOVES ACROSS SOUTHERN TEXAS INTO NORTHEASTERN
MEXICO ON SATURDAY. THE FORCING WITH THE WAVE AND DAYTIME HEATING
WILL INTERACT WITH THE MOIST AIRMASS TO GENERATE ISOLATED TO
SCATTERED SHOWERS AND THUNDERSTORMS ACROSS MUCH OF SOUTH CENTRAL
TEXAS ON SATURDAY. DOWNBURST WIND GUSTS UP TO 40 TO 50 MPH ARE
POSSIBLE WITH THE STRONGEST STORMS. LIKE TODAY...THE ACTIVITY
WILL WANE WITH SUNSET. THE SUBTROPICAL RIDGE BUILDS EAST INTO
TEXAS AS THE EASTERLY WAVE MOVES FURTHER WEST ACROSS MEXICO ON
SUNDAY. MOISTURE LEVELS DECREASE A BIT ON SUNDAY WITH THE
SEABREEZE GENERATING ISOLATED DAYTIME SHOWERS AND THUNDERSTORMS
ACROSS EASTERN AREAS. THE SUBTROPICAL RIDGE BECOMES FULLY
ESTABLISHED BY LABOR DAY AND PERSISTS THROUGH MUCH OF NEXT WEEK.
NO RAIN IS EXPECTED DUE TO SUBSIDENCE AND A DRY AIRMASS ALOFT.
LATE NEXT WEEK...THE RIDGE ERODES BACK TO THE WEST. THE GFS WANTS
TO BRING A WEAK COLD FRONT SOUTH INTO TEXAS THURSDAY AND STALL IT
JUST NORTH OF SOUTH CENTRAL TEXAS THROUGH FRIDAY. THE ECMWF AND
NOGAPS MODELS KEEP THE FRONT WELL NORTH IN THE CENTRAL PLAINS.
HAVE SLIGHT CHANCE POPS FOR POSSIBILITY SOME STORMS FORMING ALONG
THE FRONT AND DRIFTING SOUTH INTO FAR EASTERN AREAS OF SOUTH
CENTRAL TEXAS ON FRIDAY. AS FOR THE FRONTAL PASSAGE...THE GFS
BRINGS IT ACROSS SOUTH CENTRAL TEXAS ON SATURDAY WHILE THE ECMWF
BRINGS IT ACROSS LATE SUNDAY INTO SUNDAY NIGHT. THIS SHOULD BE OUR
NEXT RAIN MAKER. DAYTIME TEMPERATURES WILL BE WELL ABOVE AVERAGE
WITH HIGHS WARMING TO AROUND 100 ACROSS MUCH OF SOUTH CENTRAL
TEXAS BY LABOR DAY AND CONTINUING THROUGH MUCH OF NEXT WEEK.
NIGHTTIME TEMPERATURES WILL BE NEAR OR SLIGHTLY ABOVE AVERAGE.
