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.

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 San Angelo, TX wrote its last area forecast discussion before this flash flood warning went out at Jul 7, 7:09 AM CDT, 2 hours 40 minutes earlier.
Area forecast discussion, Jul 7, 7:09 AM CDT, 2 hours 40 minutes before
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE SAN ANGELO TX 709 AM CDT TUE JUL 7 2015 .UPDATE... We have increased POPs for this afternoon through early evening based on current radar trends. && .PREV DISCUSSION... /ISSUED 453 AM CDT TUE JUL 7 2015/ SHORT TERM... (Today and Tonight) ..Heavy rainfall and localized flash flooding possible through Wednesday afternoon... Forecast challenges remain plentiful through tomorrow. The latest satellite and radar trends show a strong MCS signature developing across the Panhandle, with a general east to southeast propagation. This convective system developed behind a linear MCS that moved across this same region and through Oklahoma yesterday evening. The net effect of all this is the weak cold front that has been discussed the last few days, is moving farther south and east than earlier thought, aided by the previously mentioned convective cold pools. This can also be seen in the latest numerical runs, with virtually all of the latest guidance showing a continued southeastward trend in the frontal timing/position for today and tonight, with the general theme being the front stalling along a Sterling City to Robert Lee to Throckmorton line around midnight. The heaviest rainfall will develop along and immediately behind this front, where a widespread 2 to 4 inches of rainfall is expected through early Wednesday afternoon, with locally higher amounts possible. Additionally, the current SPC mesoanalysis shows the "moist axis" running from Crockett County northward through the western Concho Valley and Big County, where precipitable water values are in the 1.9 to 2.1 inch range! When comparing these values to climatology, the current value of 1.9 inches at Del Rio is amongst the 95th percentile, and 1.7 inches at Midland is near the daily maximum value for today. Given the likelyhood for additional convection developing along outflow boundaries, the trend in the model data, and after coordinating with surrounding offices, a Flash Flood Watch has been issued through 1 PM Wednesday for the northern Concho Valley and Big Country. LONG TERM... (Wednesday through next Monday) Drier and warmer conditions will return to the region for the middle to end of the week. An area of high pressure currently located across the southeastern U.S., will build to the west northwest for Thursday through the weekend. Drier air and rising mid and upper-level heights will end our chance for rainfall, with warming temperatures expected. && .PRELIMINARY POINT TEMPS/POPS...
