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

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SAN ANGELO TX
1257 PM CDT THU JUL 29 2004

.SHORT TERM...PARTLY TO MOSTLY CLOUDY SKIES ARE THE RULE ACROSS THE
AREA THIS AFTERNOON. GOOD RAINS OF THE PAST SEVERAL DAYS ARE ON THE
WAY OUT AS MAIN TROUGH AXIS...WHICH HAS BEEN TO THE WEST OF THE
AREA IS NOW MOVING EAST AND IS CURRENTLY LOCATED ALMOST DIRECTLY
OVER THE AREA THIS AFTERNOON. END RESULT IS RAPIDLY DIMINISHING
CHANCES FOR RAIN. SEEMS LIKE THE BEST AREA THIS AFTERNOON AND
TONIGHT WILL BE OVER THE FAR SOUTHERN COUNTIES. CLOSE TO THE
WEAKENING FRONT WHERE CONVERGENCE WILL BE MAXIMIZED ALONG WITH HELP
FROM STRONG HEATING AND WILL GO CHANCE POPS DOWN THERE WHILE GOING
SLIGHT CHANCE ELSEWHERE. WILL CONTINUE CHANCE POPS SOUTH TOMORROW...
BUT EVEN THESE GO AWAY BY 18Z. THEN UPPER RIDGE LOOKS TO BUILD WITH
SOME FURY INTO THE WEEKEND AND INTO NEXT WEEK. WE HAVE SEEN
THIS PATTERN TRY TO SET UP BEFORE...ONLY FOR THE RIDGE TO VERIFY
FURTHER TO THE WEST THAN ORIGINALLY FORECAST. THANKS TO THE
RECENT RAINS AND EVENTUAL GREEN UP THAT IS TOO OCCUR...IT SHOULD
TAKE SOME TIME FOR TEMPERATURES TO RESPOND AND SHOULD STAY IN THE
LOW TO MIDDLE 90S THROUGH THE SHORT TERM.

&&

.LONG TERM...AS MENTIONED ABOVE SIGNIFICANT STRENGTHEN OF THE RIDGE
EXPECTED TO CONTINUE INTO THE EXTENDED AND THIS SHOULD HELP THE
AREA TO BEGIN COOKING ONCE THE MOISTURE BEGINS TO EVAPORATE THAT WE
HAVE SEEN THE PAST WEEK. IF THE CURRENT RIDGE VERIFIES AND WE HAD
NOT HAD ALL THE RAIN THE PAST WEEK...WOULD BE EASILY FORECAST 100S
ACROSS MUCH OF THE AREA. FOR NOW WILL PLAN ON KEEPING UPPER 90S THE
TOP END WITH 100 DEGREE READING OR TWO POSSIBLE BY NEXT THURSDAY
RAIN CHANCES ALMOST ZERO THROUGH THE PERIOD.
