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
Midland Regional, TX (KMAF), launched 12:00Z, 10.0 hours before the alert went out and 121 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, Aug 21, 2:17 PM CDT, 2 hours 45 minutes before
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE SAN ANGELO TX 217 PM CDT SAT AUG 21 2004 .SHORT TERM...ONE OF THE LAST WAVES IN THE SERIES IS CURRENTLY MOVING ACROSS THE AREA THIS AFTERNOON AND SHOWERS AND THUNDERSTORMS HAVE DEVELOPED WITH THIS FEATURE IN ASSOCIATION WITH OUT FLOW BOUNDARIES THAT ARE MARCHING ALL ACROSS THE AREA. DOES APPEAR THAT THIS SHOULD BE THE LAST MAJOR RAINFALL EVENT FOR THE NEXT SEVERAL DAYS. THE WATER VAPOR IMAGERY IS SHOWING THAT THE TROPICAL MOISTURE PLUM HAS SHIFTED TO THE SOUTH. THE GFS IS NOW MORE WET THAN THE ETA. THE ETA HAS HAD THE BETTER TRACK RECORD IN THE SHORT TERM AS OF LATE AND WILL CONTINUE TO TREND TOWARDS THE DRIER ETA WITH THE FORECAST PACKAGE. SHOWERS AND THUNDERSTORMS WILL CONTINUE TO BE LIKELY OVER THE SOUTHERN 2/3RDS OF THE FORECAST AREA THIS AFTERNOON AND EARLY EVENING...BUT BY MID-EVENING A DEFINITE DIMINISHING TREND SHOULD BE NOTED AS SHORT WAVE ENERGY LIFTS NORTHEAST AND SUBSIDENCE IN ITS WAKE MOVES IN AND SHUTS DOWN THE ACTIVITY OVER MUCH OF THE AREA. CAN NOT RULE OUT SOME SHOWER ACTIVITY TOMORROW AFTERNOON WITH DAYTIME HEATING...BUT AGAIN NOT EXPECTING THE WIDESPREAD HEAVY RAINS THAT WE HAVE SEEN THIS PAST WEEK. STILL EXPECTING TEMPERATURES TOO REBOUND ONCE WE GET RID OF THE CLOUD COVER...BUT WITH ALL OF THE MOISTURE AND GREEN UP...WILL BE TOUGH TO GET TOO WARM AGAIN THE REST OF THE SUMMER. && .LONG TERM...STILL EXPECTING SHORT WAVE RIDGING TO BUILD IN AHEAD OF DEVELOPING WEST COAST TROUGH THROUGH NEXT WEEK. THERE ARE SOME HINTS THAT WHAT IS LEFT OF THE CUT OFF LOW CURRENTLY OFF OF THE WEST COAST WILL MOVE ACROSS THE AREA TUESDAY NIGHT. THERE ARE SOME HINTS THAT IT COULD PRODUCE SOME THUNDERSTORM ACTIVITY TUESDAY NIGHT ACROSS THE SOUTHERN PORTIONS OF THE FORECAST AREA. AFTER THAT THERE IS NOTHING REALLY TOO KEY ON FOR PRECIPITATION IN THE REMAINDER OF THE EXTENDED WITH TEMPERATURES AT OR BELOW NORMAL. HOWEVER...WILL HAVE TO WATCH FOR WAVES AHEAD OF THE WEST COAST TROUGH THAT SHOULD BE ESTHABLISED BY THAT TIME. && .PRELIMINARY POINT TEMPS/POPS...
