The radar

The Ft Hood radar (KGRK), 133 km from the middle of the area, began a volume at 05:23 UTC, the scan nearest the moment this went out.

The archived warnings, watches and discussions in force at that minute are drawn over the scan, this one among them.

Did it verify

Not verified. The Iowa Environmental Mesonet's Cow found no qualifying storm report inside this flash flood warning while it was in force. That is not proof nothing happened: reports are thin where few people live.

Cow counts a report within 15 km of the polygon while the warning was in force: a tornado for a tornado warning; hail of 1 inch or more, a gust of 58 mph or more or wind damage for a severe thunderstorm warning; a flash flood report for a flash flood warning.

The nearest sounding before it

Fort Worth, TX (KFWD), launched 00:00Z, 5.4 hours before the alert went out and 222 km from the middle of its area. This is the routine balloon launch nearest before it, the air the forecaster had in hand, not a measurement taken for the alert.

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 San Angelo, TX wrote its last area forecast discussion before this flash flood warning went out at Oct 8, 11:45 PM CDT, 38 minutes earlier.

Area forecast discussion, Oct 8, 11:45 PM CDT, 38 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SAN ANGELO TX
1145 PM CDT SAT OCT 8 2011

.UPDATE...
SEE 06Z AVIATION DISCUSSION BELOW.

&&

.AVIATION...
MAIN AREA OF SHOWERS AND STORM HAS CONTINUED TO MOVE VERY SLOWLY
EASTWARD. THIS MEANS THAT CONDITIONS AT KABI...KSJT...AND KSOA HAVE
IMPROVED SOMEWHAT...WHILE THE TERMINALS FARTHER EAST HAVE
DETERIORATED. THIS AREA OF CONVECTION SHOULD CONTINUE TO SLIDE
EAST...AND EXPECT EVEN THOSE EASTERN AREAS TO SEE SOME IMPROVEMENT
BEFORE SUNRISE. UNTIL THAT HAPPENS THOUGH...MVFR CIGS AND VSBYS
WILL PREVAIL...DROPPING WELL INTO IFR AS THE INDIVIDUAL STORMS
TRAIN ACROSS THE AREA.

FARTHER WEST...ANOTHER AREA OF LIFT IS GENERATING MORE SCATTERED
SHOWERS AND STORMS ACROSS THE PERMIAN BASIN AND TRANS PECOS. THIS
ACTIVITY NOT EXPECTED TO BE AS WIDESPREAD OR AS INTENSE...BUT WILL
NEED TO KEEP AT LEAST A VCTS IN THE FORECAST UNTIL IT ALSO CLEARS
THE AREA.

ONCE THIS OCCURS...SHOULD SEE GRADUALLY IMPROVING CONDITIONS
AREAWIDE BY AFTERNOON.

&&

.PREV DISCUSSION... /ISSUED 1021 PM CDT SAT OCT 8 2011/

UPDATE...
QUICK UPDATE FOR CURRENT RADAR TRENDS.

DISCUSSION...
MAIN AREA OF HEAVY RAIN HAS PULLED UP NEARLY STATIONARY EXTENDING
FROM BROWNWOOD TO BRADY TO JUNCTION...WITH BROWNWOOD HAVING PICKED
UP WELL IN EXCESS OF 2 INCHES IN JUST THE LAST 90 MINUTES.
INCREASING SOUTHEAST FLOW FEEDING INTO THE CONVECTIVE LINE SHOULD
CONTINUE TO MAINTAIN THE HEAVY RAINFALL WELL INTO THE OVERNIGHT HOURS.

TO THE WEST...IR SATELLITE SHOWING INCREASING ENHANCEMENT AS
ANOTHER SHORTWAVE ROUNDS THE BASE OF THE UPPER LOW. SHOWERS AND
STORMS INCREASING ACROSS WEST TEXAS...AND THIS LIFT SHOULD HEAD
TOWARDS WEST CENTRAL TEXAS LATER TONIGHT. THUS...POTENTIAL FOR
HEAVY RAINFALL WILL CONTINUE.

PREV DISCUSSION... /ISSUED 637 PM CDT SAT OCT 8 2011/

UPDATE...
SEE 00Z AVIATION DISCUSSION BELOW.

AVIATION...
A LARGE AREA OF RAIN AND EMBEDDED THUNDERSTORMS CONTINUES ACROSS
MUCH OF WEST CENTRAL TEXAS...STRETCHING ACROSS THE
KSOA...KSJT...AND KABI TERMINALS. GIVEN VERY LITTLE EASTWARD
MOVEMENT OF THE SYSTEM...THESE SHOWERS AND STORMS WILL CONTINUE
THROUGH THE OVERNIGHT HOURS. WILL SEE MVFR CIGS AND VSBYS FOR MUCH
OF THE PERIOD...DROPPING DOWN TO IFR AS THE HEAVIER THUNDERSTORMS
MOVE OVER THE INDIVIDUAL SITES.

FARTHER EAST...KBBD AND KJCT HAVE MISSED OUT ON MOST OF THE
CONVECTION SO FAR. HOWEVER...AS OUTFLOW AND OTHER BOUNDARIES
SPREAD EAST...EXPECT THE AREA OF SHOWERS AND STORMS TO EXPAND EAST
AS WELL. MAY TAKE A FEW HOURS FOR THIS TO OCCUR...BUT EXPECT
WIDESPREAD MVFR CIGS FOR THEM TO DEVELOP AFTER MIDNIGHT.

PREV DISCUSSION... /ISSUED 352 PM CDT SAT OCT 8 2011/

SHORT TERM...
FOCUS IN THE SHORT TERM WILL BE THE CONTINUED THREAT FOR HEAVY
RAINFALL ACROSS THE ENTIRE AREA THROUGH SUNDAY AS A POTENT UPPER
LEVEL TROUGH LIFTS NORTH ACROSS THE AREA THROUGH THE PERIOD.
VERY DIFFLUENT UPPER LEVEL FLOW WITHIN THE RIGHT ENTRANCE REGION OF
THE UPPER JET AND REDEVELOPMENT OF THE LOW LEVEL JET TONIGHT WILL
RESULT IN A CONTINUATION OF WIDESPREAD SHOWERS AND THUNDERSTORMS
ACROSS THE AREA OVERNIGHT. COULD SEE A FEW STRONG STORMS OVER
SOUTHERN ZONES THROUGH THE EVENING HOURS WHERE BETTER INSTABILITY
EXISTS BUT SEVERE THREAT WILL BE RATHER LOW. CATEGORICAL POPS WILL
CONTINUE OVERNIGHT WITH THE MENTION OF HEAVY RAINFALL.

FLOW ALOFT WILL BECOME LESS DIFFLUENT ON SUNDAY AS THE MAIN JET CORE
LIFTS NORTH OF THE AREA...BUT LIFT WITH THE PASSAGE OF THE UPPER
LEVEL TROUGH WILL RESULT IN ADDITIONAL HEAVY RAINFALL ACROSS THE
AREA ON SUNDAY. HEAVIEST RAINFALL WILL SHIFT ACROSS EASTERN ZONES BY
SUNDAY AFTERNOON WITH PRECIPITATION EXPECTED TO END LATE SUNDAY NIGHT
OR EARLY MONDAY.

AS FOR QPF AMOUNTS...THE NAM CONTINUES TO PRODUCE SIGNIFICANTLY
LOWER QPF AMOUNTS THAN THE GFS AND ECMWF. SO FAR STORM TOTAL QPF
IS INDICATING 2-2.5 INCHES ACROSS TAYLOR COUNTY...WITH THE HIGHEST
TOTALS OVER NOLAN COUNTY WHERE 2 TO 4 INCHES HAVE FALLEN.
SURROUNDING THESE MAXIMA...1 TO 2 INCHES HAVE FALLEN GENERALLY WEST
OF A SONORA TO ABILENE LINE. WHILE THE NAM APPEARS TOO LIGHT WITH
ITS AMOUNTS....THEN GFS SEEMS A BIT TOO HIGH. FOLLOWED CLOSE TO HPC
GUIDANCE QPF THROUGH THE SHORT TERM WITH AN ADDITIONAL 2 TO 4 INCHES
LIKELY WITH LOCALLY HIGHER AMOUNTS THROUGH SUNDAY. DUE TO THE HEAVY
RAINFALL POTENTIAL...THE FLASH FLOOD WATCH WILL REMAIN IN EFFECT
ACROSS THE CONCHO VALLEY...BIG COUNTRY AND WESTERN PORTIONS OF THE
HEARTLAND THROUGH SUNDAY AFTERNOON. EXPECT MILD TEMPERATURES THROUGH
THE PERIOD WITH LOWS TONIGHT IN THE 60S AND HIGHS ON SUNDAY ONLY IN
THE LOW TO MID 70S.

LONG TERM...
FOR SUNDAY NIGHT...NAM QUICKLY MOVES PRECIP EAST OF THE AREA WHILE
THE MAV AND 12Z ECMWF KEEPS SOME ACTIVITY OVER THE FORECAST AREA
OVERNIGHT SUNDAY AND THROUGH THE DAY ON MONDAY. ECMWF AND MAV HAVE
BASICALLY THE SAME RAINFALL FOOTPRINT WITH THE HEAVIER AMOUNTS
OVER THE EASTERN CWA AND WITH THE ECMWF SHOWING GREATER RAINFALL
TOTALS. WILL KEEP THE WESTERN CWA DRY DURING THE DAY ON MONDAY AS
PER THE NAM BUT WILL KEEP SOME RAINFALL OVER THE EASTERN CWA PER
THE ECMWF AND MAV. AS THE UPPER TROUGH DE-AMPLIFIES INTO THE
FIRST OF THE COMING WEEK...A SECONDARY UPPER TROUGH WILL PUSH A
WEAK COLD FRONT THROUGH THE AREA LATE WEDNESDAY. WILL GO WITH A
DRY FRONTAL PASSAGE PER THE DRY ECMWF FORECASTED SOUNDING.

AFTERNOON HIGHS WILL BE IN THE UPPER 70S ON MONDAY...WARMING INTO
THE MID TO UPPER 80S THROUGH WEDNESDAY. POST FRONTAL AFTERNOON
TEMPERATURES ON THURSDAY WILL BACK INTO THE LOWER 80S WITH A
GRADUAL WARMING BACK INTO THE MID 80S BY THE END OF THE
EXTENDED...AROUND 5 DEGREES WARMER THAN CLIMO. MORNING LOWS WILL
RANGE FROM THE MID 50S TO AROUND 60.
