The episode as NWS EWX wrote it up.
An upper-level shortwave trough moved across a stationary front that was stretched across Central Texas. Some of these storms moved into South-Central Texas producing damaging wind gusts and large hail. There were also a few reports of heavy rain leading to flash flooding.

NWS Austin/San Antonio, TX wrote its last area forecast discussion before the first event at May 28, 12:22 AM CST, 3 hours 33 minutes earlier.
Area Forecast Discussion National Weather Service Austin/San Antonio TX 122 AM CDT Wed May 28 2025 ...New SHORT TERM, LONG TERM, AVIATION... .SHORT TERM... (Today through Thursday) Issued at 122 AM CDT Wed May 28 2025 Key Messages: - Severe Thunderstorm Watch through 8 AM along the Rio Grande, with large hail and damaging wind gusts primary threats along with pockets of heavy rainfall leading to isolated instances of flooding. - Level 2 out of 5 risk for severe storms late this afternoon and evening across Llano, Burnet, and Williamson County with large hail the primary threat and isolated instances of flooding. Convective chances through the overnight and during the day on Wednesday will be highly driven by mesoscale features. Thunderstorms currently moving through the southern Edwards PLateau and far northern Hill Country are riding along a stalled frontal boundary. CAMs generally indicate this weakening as it moves into the northeast Hill Country and Central Texas early this morning. Farther south, a complex of storms coming out of Mexico into southern Maverick and Webb counties has generated a MCV. The MCV is in the process of pivoting into far southern Maverick and Dimmit counties and could result in damaging wind gusts and large hail, along with heavy rainfall. This complex is indicated by most cams to track east into South Texas through the overnight hours. In between, we have finally seen some upscale growth of storms across northern Coahuila that are tracking into Val Verde County. CAMs don't have a good handle on this, and there is uncertainty with how much this fills in between the MCV to the south, which could cut off richer inflow, and storms in the far northern Hill Country. The forecast currently calls for at least scattered activity pivoting into the I-35 corridor and Coastal Plains pre-dawn through the morning hours. The afternoon forecast is much lower confidence, highly conditional on what plays out the next 6-12 hours. Also, we will be watching another cluster of storms late afternoon to the northwest, indicated by several CAMs to come out of west- central Texas southeast into at least Llano, Burnet, and Williamson counties late afternoon into the evening. A Level 2 out of 5 risk for severe storms is forecast across or near these counties, with large hail the primary threat and pockets of heavy rainfall. This activity is forecast to weaken after sunset as it moves southeast. Northwest flow aloft continues into Thursday, but lack of surface features, and the next front still north of the region, indicates convective coverage would be isolated at best. && .LONG TERM... (Thursday night through Tuesday) Issued at 122 AM CDT Wed May 28 2025 Key Messages: - Active weather pattern continues through the week with rain/storm chances and slightly cooler temperatures. On Thursday night, a deep-layer trough over the Midwestern US is expected to amplify and rotate east, producing a flow that favors the southward push of a frontal boundary from North Texas into our area. Northwesterly to west-northwesterly flow at 500mb with a proclivity for shortwave progression along the broader trough encountering moderate to high instability (especially earlier Thursday evening) will support chances for at least isolated showers and thunder, with adequate deep-layer wind shear along the front to support some severe potential. However, there are significant uncertainties concerning convective coverage, with the possibility of pre-frontal activity along the Coastal Plains and I-35 corridor potentially throwing a wrench into the setup. In turn these uncertainties will affect timing and progression of the front through our area Thursday night into Friday morning. For now, rain chances during the overnight period are held at about 20 to 30 percent, favoring the northwestern half of our CWA along the slow- moving front. Mid-level ridging quickly wedges in behind the outgoing trough, so the post-frontal airmass looks to give only a glancing pass of South- Central Texas. The upper-air arrangement is more conducive to the front stalling and washing out or reversing course over our area. Lingering cloud cover is expected Friday, along with low chances for isolated showers mainly closer to the Rio Grande where veering flow behind the front is most favorably positioned for isentropic upglide both during the day and overnight. High temperatures during the day look to settle generally in the 80s for the most... a slight downtick from Thursday, accompanied by slightly lower moisture courtesy of the post-frontal air. Surface high pressure briefly swings over East Texas Friday night into Saturday, bringing low temperatures in the mid-60s north of I- 10. While the upper-air pattern over CONUS would typically support a quieter Saturday with large-scale subsidence for our area, mid-level moisture from a possible recurving and yet-to-develop tropical cyclone over the Eastern Pacific may stream into or near our area as a cut-off low over the Baja California provides a corridor of southwesterly mid-level winds. The general synoptic setup better favors the bulk of this moisture passing to our south over deep South Texas, but a more amplified and closer cut-off low could foreseeable drive more of this moisture into our region and increase rain chances. The evolution of the synoptic pattern and where the tropical disturbances consolidates and tracks will ultimately guide where the moisture is distributed, and could influence our weather through Sunday. Heading into next week, amplifying large-scale troughing is anticipated over the Western CONUS, which should lead to a strengthening of southerly flow over South Central Texas and provide opportunities for shortwave disturbances to spark occasional rounds of thunderstorms Monday and perhaps again Tuesday. This return flow looks to also promote an increase in daytime highs back into the 90s. && .AVIATION... (06Z TAFS) Issued at 122 AM CDT Wed May 28 2025 Two complexes of storms late this evening, one moving through the far northern Hill Country and the other crossing the Rio Grande between 5T9 and LRD, will continue east with each producing a threat of hail and damaging wind gusts. In between, isolated to scattered TSRAs have developed near DRT and we will be watching how these organize overnight. Currently SAT indicates PROB30 TSRA 08Z-14Z and AUS 09Z-15Z. Additional amendments are likely to these TAFs as we assess how upstream convection evolves. && .PRELIMINARY POINT TEMPS/POPS...

A National Weather Service survey team concluded a long track microburst, associated with a supercell, caused sporadic, non-continuous wind damage in northwest Austin along the supercell's track. This consisted mainly of small to medium sized tree branches. Part of a gas station canopy collapsed onto two vehicles. Winds through this area were estimated at 55-75 mph.

A National Weather Service survey team concluded a long track microburst, associated with a supercell, occurred from central Austin, near the Hyde Park area, southeast to just east of the Austin Bergstrom International Airport. The length of the damage was approximately 10 miles long, with a path width ranging from one mile to a maximum of around 2.5 miles on the east side of Austin. Numerous trees and powerlines were damaged along the path. Large tree branches were snapped and a few trees uprooted that had shallow root systems. Minor shingle damage was observed on some homes. Maximum sustained winds were estimated to be between 65 and 85 mph. The Austin Bergstrom International Airport recorded a peak wind gust of 77 mph.
