The radar
The Austin/San Antonio radar (KEWX), 57 km from the middle of the area, began a volume at 13:20 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.
The nearest sounding before it
Del Rio, TX (KDRT), launched 12:00Z, 1.4 hours before the alert went out and 237 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...UPDATED National Weather Service Austin/San Antonio TX 554 AM CDT Sat May 23 2026 ...New AVIATION... .KEY MESSAGES... - Flood Watch remains in effect for the holiday weekend. - Locally heavy rain in multiple rounds of storms through Monday. Localized flash flooding is likely. - Active and unsettled weather pattern to continue into at least late Wednesday with addition localized flooding issues possible. && .SHORT TERM... (Today through Sunday) Issued at 1242 AM CDT Sat May 23 2026 Broad upper troughing is keeping the pattern active in the short- term, and today's relatively more quiet day is not turning out quite as quiet as we'd hoped. A line of storms looked like it was on it's last legs but was able to rebound a bit while moving through Kerrville towards San Antonio. Motion is about 35 mph so the threat of run-off issues will be relatively low despite the Flood Watch in effect. Expected rainfall amounts should be mainly 1/4 to 1 inch with the higher amounts expected to go over along the Guadalupe basin where totals were relatively lighter over the past 2 days. Another, stronger, cluster of storms moving toward San Saba had recent severe storm warning issuances, and could provide a more significant localized flood threat as this cluster appears to be in line to impact recently flood stricken areas of NE Llano, northern Burnet and NW Williamson Counties. It also could produce similar type of rainfall amounts with is forward speed also around 35 mph. The southern line continuing to strengthen, could propagate northward enough to connect with the other cluster should both hold together long enough to reach the Austin area. With all that said will make some early short range changes and perhaps discount some the midday rainfall potential as this activity overall is trending toward a nocturnal-friendly environment. This means the high rain chances expected for Saturday into Saturday evening will be lowered to account for the late night preferences. Messaging for our Situation Reports for today and tonight will be extra complicated as we aren't really able to get into expected QPF specifics outside of daily amounts and storm totals. While today and tonight trends will probably have to be dumbed down to a 50-50 shot, a larger disturbance arrives for daytime Sunday, making Sunday, the most likely period were a larger scale flood event could take place. We think our Sunday PoPs might be running a bit low given what the latest deterministic runs are showing, but at the same time we don't want to stray too far from the blends, as seemingly all models have been struggling with this pattern at one time or another. Messaging therefore continues as a daily risk of 1 to 2 isolated 3 and storm totals ending Sunday that could reach 6 inches. This means some of our totals if you go back to Tuesday's start, will be underestimated. For instance, a near 6 inch report was received on the first night at Florence, so they may end up with closer to 10 inches by Monday. However, going to those higher amounts would be confusing, and the isolated 6 inch messaging continues to cover the current time up through Monday. && .LONG TERM... (Sunday night through Friday) Issued at 1242 AM CDT Sat May 23 2026 Sunday night will appear as if the storm activity will take a break as the mid to upper level low sits over East TX leaving far East TX and LA as the likely locations for widespread heavy rains. However, this time of year and the Pwat amounts likely to still be in the area could lead to unstable NW Flow aloft storms which might favor nocturnal traits similar to what we're getting right now. There is also some deterministic model tendencies of showing the upper low retrograding and wobbling back west at some point during this general Sunday night to Monday period, which would also send PoP trends back up. If benign weather settles by Sunday night, then Monday's pattern might suggest a continued respite through the afternoon while a weak shortwave mid to upper ridge works east across the area. We'll not know these trends until Sunday afternoon at the earliest, so there's no reason to pull back on the Watch and the messaging for Monday. By Tuesday morning, the unstable SW flow pattern comes right back for another round of stormy weather that could continue through Wednesday night. Our highest PoPs of the week center on this period with the deterministic runs all in good agreement of peak activity around 12Z Wednesday. By daytime Thursday, the deterministic model runs also look to show some good agreement on a slightly better shortwave mid to upper level ridge over TX that could potentially get us a few stable weather days Thursday through Saturday. && .AVIATION... (12Z TAFS) Issued at 550 AM CDT Sat May 23 2026 Early morning cloud cover and convection has disrupted low cloud development at area TAF sites. We have scaled back to TEMPO groups for this morning as some low clouds will likely still develop between breaks in convection. We will continue to mention some PROB30 groups for afternoon convection at all sites, but this may need to be altered pending current convective trends and incoming hi-res model guidance. && .PRELIMINARY POINT TEMPS/POPS...
