The episode as NWS EWX wrote it up.
An area of thunderstorms developed along an old outflow boundary over the Southern Edwards Plateau. These storms moved toward the south and produced locally heavy rainfall that led to flash flooding.

Area Forecast Discussion National Weather Service Austin/San Antonio TX 232 PM CDT Sun Jun 4 2023 ...New SHORT TERM, LONG TERM... .SHORT TERM... (Tonight through Monday night) Issued at 232 PM CDT Sun Jun 4 2023 There is a narrow band of elevated light rain showers moving into the I35 corridor at the present time. Another area of more surface based activity is developing along an old boundary west of San Antonio where temperatures have warmed into the lower 80s. For the remainder of the day expect the areas south of I-10 to initially have the best chances for deeper convection. Things behind the elevated showers near the I35 corridor to the west look stable on satellite. Temperatures in the Hill Country remain in the lower to middle 70s behind this with some high clouds continuing and this should keep things fairly stable for at least a few more hours. Will have to monitor things closely to see if there is any destabilization there for more robust surface based convection. Where temperatures are in the 80s, instability values will be high enough to warrant a strong storm or two with perhaps some marginal hail and wind gusts. A marginal risk for severe storms is in the latest Day 1 outlook for much of the area. The other main hazard with any stronger cell will be the threat for locally heavy rainfall that could lead to minor flash flooding especially for areas that received some prior heavy rainfall. Think most of the activity today and this evening should primarily be diurnally driven with most of the activity dying off by 9-10 pm. Latest runs of the HRRR do show some redevelopment over portions of the Hill Country after midnight with a weak impulse. Will show a 20 PoP there in the overnight period to account for that. Lows tonight will be in the 60s with some lower 60s in the Hill Country. Another round of scattered showers and thunderstorms can be expected on Monday. Latest Day 2 outlook keeps us in general thunder. Locally heavy rainfall will be the main threat tomorrow. Highs will be in the 80s. Most locations will stay dry tomorrow night with lows back in the 60s with some possible near 70 degree readings near the Rio Grande. && .LONG TERM... (Tuesday through Sunday) Issued at 232 PM CDT Sun Jun 4 2023 South-Central Texas will remain under a northwesterly flow aloft with upper level ridging centered just to our west from Northern Mexico into West Texas while broad troughing continues to focus across the northern Gulf coast to the Northeast US. With not too much change, the opportunity for scattered convection is again expected from Tuesday afternoon into Tuesday evening where some locally heavy rainfall may be possible. Activity likely is to decrease through Tuesday night as majority of the model guidance keeps the activity mainly diurnally driven. Afternoon highs on Tuesday top out in the mid to upper 80s for most but some areas along the Rio Grande may get into the low 90s. The overnight low temperatures will otherwise bottom out in the mid to upper 60s with again some low 70s possible near the Rio Grande. The center of the ridge to our west nudges slowly eastward from Wednesday through the upcoming weekend. This will lead into a warming trend where slightly above average temperatures are to develop from late week into the weekend. Peak heat index values during the afternoons will climb to around or in excess of 100 degrees. While the convective chances and areal coverage should reduce compared to the start of the week, near normal moisture levels along with the continued presence of a northwest to west- northwest flow aloft will still allow for at least some low end opportunities of rain and storms to remain in the forecast. The seabreeze along with outflow/activity coming from the Trans Pecos would likely become the best triggers for any of these low end probabilities. && .AVIATION... (18Z TAFS) Issued at 1205 PM CDT Sun Jun 4 2023 Shower and storm activity has quieted down a bit early this afternoon, but with scattered activity expected in a few hours, included the mention of VCTS for a few hours this afternoon. Will need to monitor and amend for TEMPO groups if confidence increases of prevailing TSRA. Otherwise, the night time period should settle down with another chance of scattered showers and storms tomorrow afternoon. && .PRELIMINARY POINT TEMPS/POPS...
