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 6, 12:18 AM CDT, 1 hour 37 minutes earlier.

Area forecast discussion, May 6, 12:18 AM CDT, 1 hour 37 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE AUSTIN/SAN ANTONIO TX
1218 AM CDT WED MAY 6 2015

.AVIATION...
MAIN CONCERN WILL BE THE SHORT-TERM AND THE POSSIBLE CONTINUED
SHOWERS AND THUNDERSTORMS NEAR KAUS. MOST ACTIVITY IS BEGINNING TO
PUSH NORTHEAST OF THE TERMINAL AND WILL BEGIN THE TAF FOR THE NEXT
FEW HOURS WITH -SHRA PREVAILING WITH VICINITY THUNDER AND THEN
WITH ONLY VCSH FROM 8Z-11Z. CHANCES ARE TOO LOW TONIGHT FOR ANY
MENTION FOR THE OTHER TAF SITES. THE FOCUS THEN SHIFTS TO THE
CEILINGS ACROSS SOUTH CENTRAL TEXAS. PRESENTLY...KDRT IS THE ONLY
SITE WITH IFR CONDITIONS...BUT THE REST OF THE TERMINALS SHOULD
FOLLOW SHORTLY. THERE COULD BE SOME VISIBILITY RESTRICTIONS AS
WELL TOWARDS DAYBREAK...BUT PERSISTENT WIND SPEEDS AROUND 10 KNOTS
SHOULD KEEP THINGS FROM GETTING TOO OUT OF CONTROL. CEILINGS
SHOULD LIFT AROUND NOON AND THEN THERE WILL BE A CHANCE FOR
SCATTERED SHOWERS OR THUNDERSTORMS ONCE AGAIN TOMORROW AFTERNOON.
WILL HANDLE THE THREAT WITH A VCSH FOR NOW AS PROBABILITIES ARE
TOO LOW TO MENTION THUNDER FOR SEVERAL HOURS. ANOTHER ROUND OF
MVFR/IFR IS EXPECTED TOMORROW NIGHT.

&&

.PREV DISCUSSION... /ISSUED 1047 PM CDT TUE MAY 5 2015/

UPDATE...
EARLIER EVENING MODEL RUNS OF RAP AND HRRR DEPICTED A MORE
PROGRESSIVE AND SHORT-TERM FLASH FLOOD THREAT ALONG I-35 BEFORE
SHIFTING EAST AND NORTH. MID EVENING RUNS ARE NOW HOLDING BACK THE
HIGHER QPF VALUES CLOSER TO I-35 AND KEEPING A SUSTAINED THREAT
FOR A FEW MORE HOURS. AREAS FARTHER TO THE EAST WERE INCLUDED IN
CASE THE TRAINING AREA SOLIDIFIES INTO A COMPLEX AS HAS BEEN
SUGGESTED IN A RECENT NCEP MESOSCALE PRECIPITATION DISCUSSION. THE
HRRR CONTINUES TO SUGGEST A FEW STORMS FOLLOWING RIGHT MOVING
SUPERCELL PATHS...SO THERE MAY STILL BE THE POTENTIAL FOR A FEW
STRONG STORMS. HOWEVER...WILL DISCREDIT MUCH OF THE OVERNIGHT
SEVERE THREAT FOR NOW AS THIS BEHAVIOR IS NOT SUGGESTED BY
EVENING RADAR TRENDS OR SPC MESOANALYSIS TOOLS.

PREV DISCUSSION... /ISSUED 819 PM CDT TUE MAY 5 2015/

UPDATE... /LOCALLY HEAVY RAIN POSSIBLE E OF 281...N OF I-10/

A CLUSTER OF SHOWERS AND THUNDERSTORMS ARE CONCENTRATING ALONG A
CONVEYOR BELT OF GULF MOISTURE FEEDING INTO THE SOUTHERN PART OF
AN UPPER LOW LIFTING NE INTO THE CENTRAL PLAINS. FINER RESOLUTION
MODELS HAVE SHOWN INCREASED RAINFALL INTENSITIES AND QPF OVER
SOUTH CENTRAL TX...WITH INITIAL SOLUTIONS WIDELY VARIED EARLY
TODAY...NOW CONVERGING INTO THE WEAK TRAINING ECHO PATTERN SEEN
THIS EVENING. FAVORABLE JET DYNAMICS WILL LIKELY CONCENTRATE
ACTIVITY ALONG AND EAST OF I-35 INTO LATE TONIGHT. POPS WERE
INCREASED OVER MAINLY THE EASTERN SECTIONS WITH LOCALLY HEAVY
RAINFALL MENTIONED. REST OF THE FORECAST LOOKS TO BE ON
TRACK...BUT MAY NEED TO MAKE A LATE EVENING ADJUSTMENT TO POPS
SHOULD THE TRAINING PATTERN SHIFT OR DIMINISH. RAINFALL AMOUNTS
OF 1 TO 3 INCHES ARE EXPECTED...WITH FLOODING THREATS CURRENTLY
EXPECTED TO BE TOO ISOLATED TO WARRANT A FFA.

PREV DISCUSSION... /ISSUED 707 PM CDT TUE MAY 5 2015/

UPDATE...
PLEASE SEE THE 00Z AVIATION DISCUSSION BELOW.

AVIATION...
SCATTERED CONVECTION CONTINUES ALONG AND EAST OF HIGHWAY 281 THIS
EVENING. WE HAVE INCLUDED -SHRA FOR THE NEXT FEW HOURS ALONG THE
I-35 CORRIDOR...THEN TEMPO GROUPS FOR TSRA BETWEEN 03Z-06Z. FOR
NOW...WE DID NOT INCLUDE A MENTION OF PRECIPITATION AT KDRT AS IT
APPEARS ACTIVITY WILL REMAIN ISOLATED. CIGS WILL DROP INTO IFR
OVERNIGHT AND REMAIN IFR THROUGH A GOOD PORTION OF WEDNESDAY
MORNING. DAYTIME HEATING AND MIXING WILL IMPROVE SKIES BACK TO VFR
AFTER 18Z.

PREV DISCUSSION... /ISSUED 236 PM CDT TUE MAY 5 2015/

SHORT TERM (TONIGHT THROUGH WEDNESDAY NIGHT)...
UPPER AIR ANALYSIS THIS MORNING SHOWED A NEGATIVELY TILTED TROUGH
FROM THE FOUR CORNERS REGION TO THE BIG BEND WITH A RIDGE
EXTENDING FROM THE SOUTHEAST TO THE NORTHERN PLAINS. THE 250MB JET
WAS ACROSS NORTHERN MEXICO...BUT WAS LESS THAN 50 KTS. THE JET
MARKED THE BOUNDARY OF MOIST MID-LEVEL AIR TO THE SOUTH AND DRIER
AIR TO THE NORTH. AT THE SURFACE WINDS CONTINUED FROM THE
SOUTHEAST AND DEW POINT TEMPERATURES WERE FROM THE LOW TO UPPER
60S. THERE WAS A DRYLINE FROM CHILDRESS TO MARATHON. IN THE PRE-
FIRST PERIOD THIS AFTERNOON THUNDERSTORMS HAVE FORMED ALONG THE
DRYLINE AND ARE MOVING TOWARD THE EAST. SOME STORMS MAY MOVE INTO
OUR NORTHWESTERN COUNTIES. STORMS WILL BE MOVING INTO MOISTURE
RICH ENVIRONMENT AND FORECAST SOUNDINGS SHOW STEEP MID-LEVEL LAPSE
RATES. FORECAST CAPE IS 1500 TO 2000 J/KG. SOME STORMS COULD BE
STRONG TO SEVERE WITH LARGE HAIL THE MOST LIKELY THREAT.

DURING THE FIRST PERIOD STARTING THIS EVENING...THE FOUR CORNERS
TROUGH WILL MOVE TO THE NORTHEAST INTO THE CENTRAL PLAINS AND
FLATTEN AS IT MOVES INTO THE RIDGE. ANOTHER LOW WILL DIG SOUTHWARD
OVER THE WEST COAST. THIS WILL PRODUCE SOUTHWESTERLY FLOW OVER
TEXAS. THE LOW LEVELS WILL CHANGE VERY LITTLE WITH MOIST
SOUTHEASTERLY FLOW CONTINUING. THE DRYLINE WILL REMAIN OVER WEST
TEXAS AS THE MAIN FOCUS FOR THUNDERSTORM DEVELOPMENT. THE STRONG
MOIST FLOW WILL KEEP THE DRYLINE WEST OF OUR CWA. WE WILL HAVE
ANOTHER LOW CHANCE DAY FOR THUNDERSTORMS WITHOUT ANY STRONG
TRIGGER. WITH DEW POINT TEMPERATURES APPROACHING 70 THERE WILL BE
STRONG INSTABILITY AND ONLY A WEAK CAP. ANY STORMS THAT DO FORM
COULD BE STRONG TO SEVERE. SPC HAS THE WESTERN HALF OF OUR AREA IN
THE MARGINAL RISK FOR WEDNESDAY AFTERNOON AND EVENING.

LONG TERM (THURSDAY THROUGH TUESDAY)...
THE UPPER LEVEL LOW WILL CONTINUE SOUTHWARD OVER THE WEST COAST
THURSDAY. THIS FEATURE WILL BEGIN TO MOVE TO THE EAST FRIDAY AND
THEN TO THE NORTHEAST OVER THE WEEKEND. THE UPPER FLOW WILL REMAIN
SOUTHWESTERLY DURING THIS TIME FRAME. THE ONLY SURFACE FEATURE
WILL BE THE DRYLINE TO THE WEST AND THE LOW LEVEL FLOW WILL
CONTINUE TO BE FROM THE SOUTHEAST KEEPING IT THERE. THIS WILL MEAN
AN EXTENDED PERIOD OF LOW CHANCE POPS WITH A CONDITIONALLY
UNSTABLE ATMOSPHERE...BUT NOT TRIGGER FOR CONVECTION. INSTABILITY
WILL BE SUFFICIENT FOR STRONG STORMS THROUGH THIS PERIOD. MONDAY
AND MONDAY NIGHT A COLD FRONT WILL MOVE THROUGH THE REGION. THIS
MAY PROVIDE A BETTER FOCUS FOR STORMS OVER A WIDER AREA.
