Southerly flow in the boundary layer brought a warm, moist airmass to South Central Texas. There was sufficient cold air advection above this layer to break the cap and generate thunderstorms late in the evening.

The episode as NWS EWX wrote it up.
Southerly flow in the boundary layer brought a warm, moist airmass to South Central Texas. There was sufficient cold air advection above this layer to break the cap and generate thunderstorms late in the evening. Some of these storms produced large hail, damaging wind gusts, and locally heavy rain.
The local office's own words before the first event, 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 the first event at Apr 10, 1:24 PM CST, 5 hours 51 minutes earlier.
Area Forecast Discussion National Weather Service Austin/San Antonio TX 224 PM CDT Sun Apr 10 2022 .SHORT TERM (Today through Monday Night)... Seeing some changes in the low-levels noted on satellite this afternoon, as low-clouds continue across the Coastal Plains and east of the I35. This is a sign of increasing low-level moisture for the eastern areas as continued deep southerly flow prevails over that region. Across the west, dry air remains in place and some breezy southwesterly flow will likely lead to near critical to critical fire weather conditions for Val Verde County this afternoon. Latest aircraft soundings at AUS and SAT both show a very large CAP above the moist boundary layer. This should limit any surface based convection today, but some recent runs of the HRRR show some elevated showers associated with some mid-level moisture in the western CWA. Will continue to hold onto the mention of PoPs with a 10 PoP through 3z to account for this and the small chance an isolated storm is able to break through the cap. For tonight, low clouds are likely for the eastern 2/3rds of the area with the increase in moisture continuing. Lows will therefore be warmer, in the lower to upper 60s across the region. Model soundings are continuing to show a stout cap in place across the area Monday afternoon. Not expecting to see much in the way of convective development once again tomorrow. However, if anything does initiate, steep mid-level lapse rates would support the threat of large hail and damaging winds. The fire weather threat tomorrow will be anchored by continued very dry humidity values in the west. However, winds in this same area tomorrow will be in the 7-12 mph range and not expecting any need for fire weather headlines. Highs tomorrow will be in the middle 80s in the east and into the upper 90s in the west. More low clouds are expected Monday night with lows in the middle 60s to near 70 degrees. && .LONG TERM (Tuesday through Saturday night)... On Tuesday, warm, moist air will be in place with dew points in the 60s to near 70. While cloud cover will likely remain over our far eastern counties much of the day, sunshine in the afternoon will allow temperatures to rise to near 100 over our southwestern areas. A trough axis over the western CONUS will be in the process of taking on a more negative tilt as it pushes towards the high Plains during the day. While it's primary mid-level lift will remain well to our north during the afternoon and evening, a subtropical jet to it's south looks to potentially set up with it's left exit region near south-central Texas. In addition a shortwave embedded within the WSW flow aloft should bring at least modest PVA to the area late in the day, and a dryline will mix east towards US-281. West of it, elevated to near-critical fire weather conditions are expected. East, thermodynamic profiles could support a potential for severe storms over the east half of our region, but the question becomes: Will there be enough low to mid-level mixing and lift to overcome the cap? There is a dichotomy in the available model guidance with the answer to this question, with the NAM holding onto and even strengthening the capping inversion in the afternoon while the GFS depicts it eroding. If storms are able to develop (~30% chance at this time) the potential would be there for large to very large hail (primary risk) , damaging winds, and a low chance for a tornado. However, the opposite solution would mean another day with no rain and a continued worsening of drought conditions across the Hill Country. For the time being, this morning's SPC outlook is still valid, with a Marginal Risk of severe storms remains in place east of Kerrville to Castroville to Charlotte, with a Slight Risk for areas northeast of Llano to San Marcos to La Grange. A secondary shower and storm chance may arrive overnight into Wednesday morning ahead of this systems cold front. Although this wouldn't be the primary severe threat, there would still be a chance for some stronger storms with this round. It'll move out quickly by midday, with brisk, dry NW flow behind it. Red flag warnings will be needed for much if not all of the area as RH will fall into the single digits across the west half of the region and teens to low 20s east. Winds will be weakest over the Coastal Plains but still in the 10-15 mph range in the afternoon. Zonal flow returns aloft on Thursday, and sfc winds will gradually return to the E and then SE through the day. Temperatures will be near to slightly above normal still behind the front Wednesday through Friday. Continued elevated to near critical fire weather conditions are expected, but moisture will begin to return overnight into Friday. Could be a low chance for some precip on Friday, but forecast confidence decreases significantly at that time. We do anticipate a return to well-above normal temperatures on Saturday. && .PRELIMINARY POINT TEMPS/POPS...

Critical fire weather conditions are expected today across Val Verde County and a Red Flag Warning is in effect for this area. Elsewhere across South Central Texas, elevated to near-critical fire weather conditions are expected today due to either breezy winds or low humidity. There is a slight chance for isolated thunderstorms late this afternoon and evening. If any storms develop, a strong storm or two is possible, with small hail and gusty winds the primary threats. .DAYS TWO THROUGH SEVEN...Monday through Saturday. Elevated to near critical fire weather conditions are forecast on Wednesday across much of South Central Texas. There is a chance for storms across portions of the eastern Hill Country and along and east of the I-35 and I-37 corridors Tuesday afternoon through Tuesday night. There is the potential for some storms to become severe storms during this time, with very large hail and damaging wind gusts the primary threats. There is currently a Marginal (1/5) to Slight (2/5) Risk for severe storms across this area on Tuesday. .SPOTTER INFORMATION STATEMENT... Spotter activation is not anticipated.
