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, 3.2 hours before the alert went out and 126 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.

* UNTIL 215 PM CST

* AT 1205 PM CST...NATIONAL WEATHER SERVICE DOPPLER RADAR INDICATED 
  SCATTERED THUNDERSTORMS WITH VERY HEAVY RAINFALL TRAINING ACROSS 
  THE WARNED AREA. LATEST TRENDS SHOW THE STORMS HAVE BECOME MUCH 
  MORE SCATTERED IN THE PAST HOUR...HOWEVER EXTENSIVE FLOODING IN 
  ONGOING ACROSS PORTIONS OF VICTORIA COUNTY AND ANY ADDITIONAL

  THE 4 TO 6 INCHES THAT FELL LAST NIGHT. ADDITIONAL ISOLATED

  SHIFTING MAINLY SOUTH OF HIGHWAY 59.

* SLOW MOVING SCATTERED THUNDERSTORMS ARE PRODUCING HEAVY RAINFALL 
  IN THE WARNED AREA. RUNOFF FROM THIS EXCESSIVE RAINFALL WILL 
  CAUSE FLOODING TO OCCUR. SOME LOCATIONS THAT WILL EXPERIENCE 
  FLOODING INCLUDE...VICTORIA...MISSION VALLEY...AND NURSERY.

EXCESSIVE RUNOFF FROM HEAVY RAINFALL WILL CAUSE FLOODING OF SMALL 
CREEKS AND STREAMS...HIGHWAYS AND UNDERPASSES. ADDITIONALLY...COUNTRY

LYING AREAS ARE SUBJECT TO FLOODING AND LAW ENFORCEMENT HAS REPORTED
