The radar
The Austin/San Antonio radar (KEWX), 104 km from the middle of the area, began a volume at 20:13 UTC, the scan nearest the moment this went out.

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
Del Rio, TX (KDRT), launched 12:00Z, 8.2 hours before the alert went out and 259 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 National Weather Service Austin/San Antonio TX 303 PM CDT Sat Jul 5 2025 ...New SHORT TERM, LONG TERM, AVIATION... .KEY MESSAGES... - Threat of Flash Flooding from slow moving and repeat heavy rains this evening. A Flood Watch remains in effect for the Hill Country and I-35 corridor through 10 PM CDT. - Continued unseasonably wet and "cool" into Monday. - Turning seasonably drier and warmer next week. && .SHORT TERM /THROUGH SUNDAY NIGHT/... Issued at 250 PM CDT Sat Jul 5 2025 A mid level MCV and unusually moist airmass continue move across our CWA. Forcing by this feature will generate rounds of showers and isolated thunderstorms. Storm motion will be slow. The tropical nature of the airmass is leading to efficient warm rain processes. As a result, locally heavy rain will be possible this evening. New rainfall of 1 to 3 inches with isolated amounts up to 5 inches is possible. This rain will aggravate ongoing flooding and likely create new flooding as soils are saturated making runoff more rapid. The heaviest rains will be over the Hill Country to along and east of the I-35 Corridor this evening. A Flood Watch is now in effect until 10pm. Most models show the rain shifting to our western areas Sunday. Models are showing lower rainfall totals for Sunday. The clouds and rain areas will conspire to keep daytime temperatures below to well below normal. && .LONG TERM /MONDAY THROUGH SATURDAY/... Issued at 250 PM CDT Sat Jul 5 2025 The mid level feature may remain close enough to our CWA to generate isolated showers and isolated Monday. The airmass will remain moist and there will be a possibility of locally heavy downpours. Most models/ensembles show the subtropical ridge pushing the mid level feature away from our area while bringing increased subsidence and decreasing moisture. This will keep rainfall out of the forecast for the remainder of this coming week. However, the GFS shows an inverted trough moving in from the east which could bring chances of showers and isolated thunderstorms Tuesday and Wednesday. This solution is not in the NBM and thus not in our forecast. Later forecasts may introduce rain chances should this become a trend. Increased sunshine will lead to temperatures warming to near or slightly above averages. && .AVIATION /20Z SATURDAY THROUGH THURSDAY/... (18Z TAFS) Issued at 250 PM CDT Sat Jul 5 2025 Isolated TSRA with scattered to widespread RA continues across the I- 35 corridor, with decreasing trends in TS coverage observed over the last 6 hours. CIGs range from MVFR to IFR within this activity but are expected to gradually lift to VFR with isolated MVFR this afternoon. Due to uncertainties in TS activity later today, have maintained a PROB30 at AUS where thunder likelihood is slightly higher than at other terminals. Expect a return of MVFR to IFR CIGs overnight after 08Z near and over the I-35 terminals, expanding to DRT closer to 14Z. CIGs should recover after 16Z-18Z, but timing and rate of improvement is low confidence due to significant model uncertainties in handling the disturbance associated with the current shower activity over the area. && .PRELIMINARY POINT TEMPS/POPS...
