The radar

The Corpus Christi radar (KCRP), 18 km from the middle of the area, began a volume at 21:27 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 12:00Z, 9.5 hours before the alert went out and 6 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.

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE CORPUS CHRISTI TX
330 PM CDT SAT SEP 27 2014

.SHORT TERM (TODAY THROUGH SUNDAY NIGHT)...THREAT FOR LOCALLY
HEAVY RAIN WILL CONTINUE THIS AFTERNOON INTO THE EARLY EVENING
ACROSS EASTERN SECTIONS OF THE AREA. UPPER LOW TO THE NORTHWEST
CONTINUES TO SLOWLY MOVE TO THE EAST THIS AFTERNOON. AT THE
SURFACE...COASTAL TROUGH STILL EXISTS AND THESE TWO FEATURES ARE
COMBINING TO PRODUCE WIDESPREAD SHOWERS WITH EMBEDDED
THUNDERSTORMS MAINLY EAST OF HIGHWAY 16. REPORTS OF FLOODING HAVE
BEEN RECEIVED IN AND AROUND THE KINGSVILLE AREA THIS AFTERNOON
AND THIS HEAVY RAIN THREAT WILL CONTINUE AS DEEP TROPICAL MOISTURE
REMAINS IN PLACE. ACROSS THE WESTERN ZONES...WATER VAPORY
SATELLITE IMAGERY SHOWS DRYING IS ALL READY UNDERWAY AND HAVE CUT
POPS BACK SIGNIFICANTLY OVER THE RIO GRANDE PLAINS THIS AFTERNOON
AND EVENING. A HIGH RIP CURRENT RISK WILL PERSIST THROUGH THIS
EVENING AS SWELL HEIGHTS AND SWELL PERIOD REMAIN ELEVATED. TIDES

SH/TSRA WED-THU. TEMPERATURES WILL CONTINUE TO RUN A FEW DEGREES
ABOVE NORMAL. THE UPPER TROUGH MOVES EAST INTO THE MID SOUTH BY
FRIDAY WITH A COLD FRONT SETTLING INTO SOUTH TEXAS IN ITS WAKE.
MAINTAINED LOW END CHC POPS AHEAD OF THE FRONT THU NGT/FRI SUPPORTED
