The radar
The Laughlin AFB radar (KDFX), 133 km from the middle of the area, began a volume at 04:48 UTC, the scan nearest the moment this went out.

Did it verify
Not verified. The Iowa Environmental Mesonet's Cow found no qualifying storm report inside this severe thunderstorm 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.

TB3What forecasters said that day
The local office's own words before this severe thunderstorm warning went out, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.
NWS Austin/San Antonio, TX wrote its last area forecast discussion before this severe thunderstorm warning went out at Apr 10, 7:23 PM CDT, 4 hours 23 minutes earlier.
Area forecast discussion, Apr 10, 7:23 PM CDT, 4 hours 23 minutes before
Area Forecast Discussion National Weather Service Austin/San Antonio TX 723 PM CDT Mon Apr 10 2017 .MESOSCALE UPDATE... Spent a good amount of time attempting to add some timing precision to the WX/PoP/QPF grids for the next 18 hours. While some initial CI has begun in the vicinity of San Antonio, capping continues to hold on preventing cells from growing upscale without help from a surface boundary...unlike the convection farther north. In regards to activity farther north, SPC mesoanalysis and proximity RAP soundings show the cap eroded along the boundary with surface dewpoints at or near 70 degrees and 3000+ J/KG to tap into. Convergence along the front is maximized from north of Kerrville and northeast whereas farther west, weaker low level flow and less favorable moisture flux vector orientation to the front has kept the majority of the plateau from convecting. CAM guidance continues to ramp up QPF values however some guidance, especially the HRRR, appears to be overconvecting in the next 2-4 hours. While these values are not being disregarded, the TTU-WRF model has been generally handling this convection thus far rather well. It continues to convect more along the favorable convergent zone along the front, becoming outflow dominant, and thus convecting farther southeast along the line beginning around 10PM. These new storms will be able to capitalize on the high instability and PWAT values of over 1.5" advecting into the I-35 corridor allowing for hourly rainfall rates of over 2 inches per hour possible. This means that the QPF forecasts of 2-4 inches with isolated up to 7 inches is still very much valid for all areas east of the Edwards escarpment as well as along and east of the I-35 corridor. Also, with the high instability and appreciable shear, quarter size hail and damaging winds are also still possible through 11PM. However, these threats are secondary to the flash flood threat, which is still the more significant impact for the next 12 hours. && .PREV DISCUSSION... /ISSUED 622 PM CDT Mon Apr 10 2017/ AVIATION DISCUSSION...FOR 00Z TAF PERIOD... Expecting TSRA development northwest of the KAUS terminal in the first 6 hours of the TAF period. Some isolated development has already been observed in the vicinity but have been short lived with sporadic ltng. Included TEMPO for possible iso storms for first 3 hours and then prevailing afterwards. Latest models have a line of TSRA to begin impacting around 03Z and an hour or so later for KSAT/KSSF. Hvy rain will be the primary impact to the terminals in addition to lightning thus reduced VIS as a result. CIGs will be difficult but should fluctuate around low end MVFR and IFR during storm impact. Activity is expected to be clear of all terminals by 10-12Z. However cloud cover is expected to prevail through much of the morning hours. Only marginal improvement to CIGs is expected by the afternoon hours tomorrow. PREV DISCUSSION... /ISSUED 332 PM CDT Mon Apr 10 2017/ SHORT TERM (Tonight through Tuesday Night)... .Dangerous Flash Flooding Event Possible Late This Afternoon through Tonight across South Central Texas... Complex weather scenario taking shape late this afternoon through tonight. The cold front was located just south of a Stephenville to San Angelo line at 3 PM with showers and storms developing along and just behind it in West Central Texas. Additional isolated to scattered showers have developed through the afternoon beneath a mid level cap across Central Texas. Aircraft sounding data from AUS indicates the mid level cap still in place, but this is forecast to erode late this afternoon and evening as the front approaches the region. Initially discrete storms could pose a hail threat across the northern Hill Country and Central Texas through the early evening. Signals in hi resolution models then transition into an organized complex of storms, but there are some difference in timing on how fast this happens. Should this happen this could support a threat of damaging straight line winds through the CWA. However, the main concern we are messaging will be the heavy rainfall potential that could lead to flash flooding. Precipitable water values of 1.6-1.8 inches are pooling over the region south of the front. This is nearly 2 standard deviations above average. Initial slow motions of the storms and complex will yield pockets of intense rainfall rates this evening through portions of the overnight, as indicated by runs of the HRRR. Models the past three runs have trended farther south and with higher QPF amounts into much of the southern and eastern Hill Country as well as I-35 corridor. GEFS plumes for both Austin and San Antonio have trended up, with the lowest member at Austin around 2", highest at 4.3", and mean 2.87". Some of the high resolution guidance suggests the highest amounts farther south toward the San Antonio metro area. It is difficult at this time frame to determine where the heavier pockets may occur as there is uncertainty with the mesoscale evolution of the system. But generally 2-4" is expected across the Flash Flood Watch area with isolated amounts up to 7". It is important to stress the flash flooding potential with this system, especially since this will be occurring at night when it is harder to recognize the dangers of flash flooding. Tomorrow's chances for rainfall will depend entirely on how organized the system evolves tonight. With hi resolution guidance trended towards and MCS, the atmosphere may become worked over and stabilized for Tuesday. LONG TERM (Wednesday through Monday)... Chances for showers and thunderstorms will remain in the forecast through the rest of the week with slightly greater chances Thursday as a trough shifts through the region. No concentrated signals appear to warrant hazard mention at this time during the long-term period. Diurnal showers and thunderstorms look to be likely each afternoon through the week as a unsettled and active southern jetstream branch helps promote lift with the continued moist airmass in place. Thursday and Friday appears to be a slightly better concentrated day with the passage of stronger trough axis. Weak ridging over the weekend may help to keep the area dry. && .PRELIMINARY POINT TEMPS/POPS...
