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
Fort Worth, TX (KFWD), launched 12:00Z, 8.1 hours before the alert went out and 238 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.

NWS Austin/San Antonio, TX wrote its last area forecast discussion before this flash flood warning went out at Jul 6, 2:33 PM CDT, 30 minutes earlier.
Area forecast discussion, Jul 6, 2:33 PM CDT, 30 minutes before
Area Forecast Discussion National Weather Service Austin/San Antonio TX 233 PM CDT Sun Jul 6 2025 .SHORT TERM /THROUGH MONDAY NIGHT/... Issued at 230 PM CDT Sun Jul 6 2025 A mid level MCV and unusually moist airmass, with PWs of 1.7 to 2.4 inches, remain in place over our area. We're seeing showers and thunderstorms develop across the CWA and expect this to continue until this evening. With the high PW and slow cell motion, locally heavy rain will be possible. A Flood Watch remains in effect for the Hill Country and I-35 Corridor. Rainfall amounts of 2 to 4 inches are expected with isolated amounts up to 10 inches possible. This rain will aggravate ongoing flooding and likely create new flooding as soils are saturated making runoff more rapid. The heaviest rain is expected over the Hill Country to along the I-35 corridor. The MCV will weaken some by Monday with only a slight decrease in moisture/PWs. Showers and thunderstorms may be less focused and have only slight chances on Monday. The clouds and rain areas will keep daytime temperatures below to well below average. && .LONG TERM /TUESDAY THROUGH SUNDAY/... Issued at 230 PM CDT Sun Jul 6 2025 The mid level feature will be replaced by an inverted trough moving onto the Texas coast Tuesday keeping moisture levels elevated. The blended guidance has caught on to the trends of the last several model runs and indicates low chances of showers and thunderstorms Tuesday afternoon and again Wednesday afternoon. This will spread from the Coastal Plains to the Hill Country. The blended model solution shows the subtropical ridge building over the region over the latter part of the week bringing dry and warmer weather. && .AVIATION /19Z SUNDAY THROUGH FRIDAY/... (18Z TAFS) Issued at 230 PM CDT Sun Jul 6 2025 Opted to go with PROB30s to account for uncertainty with -TSRA timing and coverage. Ultimately, any storm that forms would bring extreme rainfall rates and a reduction in visibilities. Winds should remain southeasterly at about 10 kts through the evening before falling to less than 5 kts overnight. Have kept vicinity showers in play as well through today and into the overnight hours. MVFR ceilings return after 9-10Z Monday morning and stick around through late morning Monday. && .PRELIMINARY POINT TEMPS/POPS...
