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, 1.1 hours before the alert went out and 98 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 National Weather Service Austin/San Antonio TX 647 AM CDT Fri May 1 2026 ...New AVIATION... .KEY MESSAGES... - A Flood Watch remains in effect for locally heavy rain across the area along and north of I-10/Hwy 90 through this evening. - Isolated to scattered thunderstorms are likely into early evening. Some could be strong to severe from San Antonio to the Coastal Plains. - Dry and cooler weather for the weekend with a warming trend for next week. && .SHORT TERM... (Today through Saturday) Issued at 131 AM CDT Fri May 1 2026 An upper trough is moving across the Gulf of California and the flow over TX is becoming southwesterly. The front that moved through our CWA Wednesday has stalled across South Texas and northeastern Mexico. Winds across the area are from the northeast which has brought cooler air. Dewpoints showed an initial drop, but have rebounded and are in the 60s. The deeper atmosphere is very moist with PW at DRT this evening 1.80" which is above the 90th percentile of the observation database. The upper trough will move across TX today providing a lifting mechanism to interact with our very moist airmass. Scattered showers and thunderstorms are likely to be ongoing at the start of this period. Some storms will produce locally heavy rain. We will continue the Flood Watch for the area along and north of I-10/Hwy 90. For the daytime hours today, the heaviest rain should be from the Hill Country to the Coastal Plains. Widespread rainfall totals of 1-3 inches are possible today through this evening which will be 2-4 inches when added to rain from Thursday night. There may be a few spots that get up to 6 inches. In addition to the flood threat, there may be enough CAPE and shear to generate a few severe thunderstorms from San Antonio to the Coastal Plains. All severe modes are possible, the risk is Level 1. North- northeasterly winds will bring a more stable airmass to the region tonight. Some showers and thunderstorms will linger across the east until around midnight, but shouldn't produce much more rain. Cooler air will move in. Lows Saturday morning will range from the mid 40s over the Southern Edwards Plateau and Hill Country to the mid 50s along the Rio Grande. Saturday will be dry and mostly sunny. Highs will remain on the cool side mostly in the 70s. && .LONG TERM... (Saturday night through Thursday) Issued at 131 AM CDT Fri May 1 2026 Saturday night an upper ridge will start to build over TX from the west. Surface high pressure will move across the area. Sunday morning will be a couple of degrees cooler than Saturday, but then we will begin to warm back up. Dry weather will continue into the middle of the week. Highs will be back to well above normal by Tuesday. Wednesday a dryline will bring low rain chances to the east. Thursday another frontal boundary will bring more widespread, but still low, chances for showers and storms. Cooler air will move in behind this front bringing temperatures back down to near normal. && .AVIATION... (12Z TAFS) Issued at 640 AM CDT Fri May 1 2026 IFR to MVFR conditions are forecast for the area airports through Saturday morning. Several rounds of showers and storms are forecast to push across the terminals throughout the day as an upper level short wave moves through the region. Any storm that moves over the terminals could have lightning, reduced visibilities, and strong wind gusts. A northerly wind flow is forecast for today into Saturday with breezy and gusty conditions this afternoon through the evening. The storm activity comes to an end in the evening. && .PRELIMINARY POINT TEMPS/POPS...
