The radar

The Austin/San Antonio radar (KEWX), 62 km from the middle of the area, began a volume at 08:50 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

Corpus Christi, TX (KCRP), launched 00:00Z, 8.8 hours before the alert went out and 249 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 Austin/San Antonio, TX wrote its last area forecast discussion before this flash flood warning went out at Oct 31, 3:43 AM CDT, 4 minutes earlier.

Area forecast discussion, Oct 31, 3:43 AM CDT, 4 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE AUSTIN/SAN ANTONIO TX
343 AM CDT SAT OCT 31 2015

.SHORT TERM (TODAY THROUGH SUNDAY)...
FLASH FLOOD THREAT CONTINUES OVER NEARLY ALL OF THE WATCH
AREA...BUT THE THREAT WILL SHOW A RAPID DECREASE FROM WEST TO EAST
WITH THE FINAL PUSH OF THE SQUALL LINE. WITH A PROGRESSIVE SPEED
OF 30-35 MPH THE FLOOR OF EXPECTED RAINFALL FROM THIS LINE IS
PROBABLY IN THE 1/2 TO 3/4 INCH RANGE WITH SPOTTY TOTALS OF 1 TO
2 INCHES. A FEW CELLS THAT FORM AHEAD OF THE LINE COULD LEAD TO AN
ISOLATED 3 INCH TOTAL. THERE IS A GOOD CHANCE THAT PART OF THE
FLASH FLOOD WATCH AREA COULD BE TRIMMED DOWN FROM THE WEST AT
DAYBREAK...AND VERY LIKELY THAT THE THREAT SHOULD END OVER ALL OUR
FORECAST COUNTIES BY 15Z. THERE REMAINS A SMALL THREAT FOR STRONG
TO SEVERE DOWNDRAFTS AS BULK SHEAR REMAINS HIGH OVERNIGHT.

SOME LIGHT WRAP-AROUND CLOUDINESS IS FORECAST TO LINGER INTO THE
DAYTIME WITH SOME LIGHT SHOWERS...BUT RAINS SHOULD CLEAR
SIGNIFICANTLY BY MIDDAY. MOSTLY CLEAR SKIES SHOULD BUILD OVER ALL
AREAS LATE THIS EVENING WITH A LIGHTER NORTH BREEZE IN THE WAKE OF
THIS UPPER DISTURBANCE THAN FROM THE TROPICAL STORM INFLUENCED
UPPER LOW FROM LAST WEEK. A SIMILAR AMOUNT OF COLD AIR ADVECTION
IS EXPECTED WITH A PLEASANT EVENING EXPECTED FOR HALLOWEEN RELATED
ACTIVITIES. SUNDAY WILL CONTINUE A MILD AND DRIER PATTERN.

&&

.LONG TERM (SUNDAY NIGHT THROUGH FRIDAY)...
THE EARLY WORK WEEK FORECAST CALLS FOR MORE MILD AND MOSTLY DRY
WEATHER THROUGH TUESDAY...BUT ANOTHER TROUGH IS EXPECTED TO DIG
SOUTH OVER THE PACIFIC COAST BY THEN. SOUTHERLY WINDS SHOULD
INCREASE AND RESTORE HIGHER DEW POINTS AND BRING BACK SOME
CLOUDS...BREEZY CONDITIONS AND DECREASING DIURNAL RANGES BY
WEDNESDAY MORNING. HIGH PWAT VALUES ARE FORECAST TO BE POSITIONED
OVER THE SOUTH TX COAST BY THIS TIME...WITH RAPID MOISTURE
ADVECTION LIKELY TO PROMOTE SCATTERED SHOWERS AND A FEW
THUNDERSTORMS OVER THE AREA WEDNESDAY. PRIOR MODEL CYCLES WERE
GENERATING HIGHER QPF AMOUNTS AND MORE HEAVY RAIN EVENTS...BUT
THIS MORNINGS COLLECTION SHOWS LESS POTENTIAL FOR SURFACE
CONVERGENCE AND MORE OF A STREAMER SHOWER ENVIRONMENT EARLY ON.
THE MOST RECENT RUNS ALSO KEEP A MORE SHALLOW TROUGH BASE AND A
MORE NORTHWARD EJECTION TRACK AS IT LIFTS NE INTO THE PLAINS BY
FRIDAY. THUS CHANCE CATEGORY POPS CONTINUE THROUGH MUCH OF THE
EXTENDED PERIOD...BUT WITH LOWER QPF POTENTIAL. THE BEST CHANCE
MAY WIND UP BEING LATE FRIDAY AS THE ECMWF IS TRENDING TOWARD THE
MORE CONSISTENT GFS WHICH BRINGS A WEAK FRONTAL FOCUS INTO THE
AREA.
