Golf ball-sized hail hammered parts of central Texas on the afternoon of April 18, 2026, as a line of severe thunderstorms rolled across the region’s Hill Country and I-35 corridor, leaving residents scrambling to move vehicles under cover and brace for roof damage.
“It sounded like someone was throwing rocks at the house for 20 minutes straight,” one homeowner in Williamson County posted on a neighborhood message board shortly after the storms passed. Across the region, residents in Hays, Travis, Comal, and Bexar counties reported similar scenes: cars left pockmarked in driveways, gardens shredded, and chunks of ice piled in yards like dirty snow.
The Storm Prediction Center, NOAA’s national severe weather tracking arm, logged multiple hail reports from across central Texas that afternoon. Stones ranged from quarter-sized (about one inch across) to golf ball-sized (roughly 1.75 inches), large enough to crack windshields, dent sheet metal, and punch through aging roof shingles.
The National Weather Service office in Austin/San Antonio, which serves as the warning authority for communities stretching from the Hill Country through the San Antonio metro, flagged large hail and damaging winds as the primary threats. Severe thunderstorm warnings went out in real time, urging residents and emergency managers to take cover.
What the storm reports show
The SPC’s preliminary storm log for April 18 includes time stamps, geographic coordinates, and hail-size estimates compiled from trained storm spotters, law enforcement, and automated sensors. Each entry functions like a pin on a map, showing where the most intense hail was observed and when it fell. Reports clustered around communities in Williamson, Travis, Hays, Comal, and Bexar counties, with additional entries scattered across surrounding areas of south-central Texas. The data confirms that multiple towns took hits during a narrow afternoon window, consistent with the kind of explosive convection that develops when spring daytime heating destabilizes the atmosphere over the region.
The NWS office’s hazard messaging reinforces the picture. Its forecast discussions described atmospheric conditions ripe for large hail and strong wind gusts, and the severe thunderstorm warnings that followed were designed to trigger protective action: get indoors, pull vehicles into garages, stay away from windows.
Both data streams point to the same conclusion: significant hail struck central Texas, and damaging winds came with it. No conflicting information has surfaced from official channels about the event’s occurrence or general severity.
What is still unknown
The full toll of the storms has not been tallied. No finalized damage estimates, injury counts, or fatality reports have appeared in federal databases. The NCEI Storm Events Database, the federal government’s definitive archive for severe weather impacts, has not yet posted completed entries for April 2026. That database typically lags weeks or even months behind real-time reports because each entry must be verified for location accuracy, magnitude, and documented impacts before publication.
Local emergency management agencies have not released public statements detailing specific property damage, shelter activations, or response operations tied to the April 18 storms. That means the scope of harm to homes, vehicles, and agricultural operations along the storm’s path remains unclear. Communities along the I-35 corridor in Travis and Williamson counties have grown rapidly in recent years, adding subdivisions and vehicle-dense commercial areas that are particularly exposed to hail of this size, but no official count of affected properties has been compiled.
Whether the storms disrupted air travel at Austin-Bergstrom International Airport or San Antonio International, or caused significant road closures, also lacks confirmation in available records. And no post-event climate analysis from NOAA has yet placed the April 18 storms in the context of broader 2026 spring weather patterns, leaving open the question of whether the event was unusually intense or a routine part of the season.
Why the gap matters
The delay between preliminary storm logs and finalized federal records is a recurring challenge after severe weather. The SPC data can confirm that a storm happened and pinpoint where hail fell, but the dollar figures for insured losses, agricultural damage, and infrastructure repairs take time to assemble. Residents waiting on insurance adjusters or federal assistance may face a slower process if multiple severe weather episodes stack up during peak spring season and strain assessment resources.
What residents should do now
For anyone in the storm’s path, the most important step is to document damage immediately. Photograph dented vehicles, cracked windshields, and any visible roof or gutter damage from a safe vantage point. Contact insurance providers early; claims volume tends to spike after widespread hail events, and getting in the queue matters.
Keeping a copy or screenshot of the SPC storm report for your county can help support a claim by establishing that a verified severe weather event occurred at a specific time and place. Texas homeowners and auto policies generally cover hail damage, but adjusters will want evidence tying the damage to a confirmed storm.
Roof inspections deserve special attention. Hail impacts are often invisible from ground level, and small punctures in shingles or flashing can lead to leaks weeks later. Renters should notify property managers quickly so inspections and repairs can be scheduled before secondary water damage sets in.
Where central Texas sits in the nation’s hail corridor
None of this is unusual for the region. According to NOAA climatology data, central Texas sits squarely in one of the most hail-prone corridors in the country, and April is the heart of the season. Golf ball-sized stones carry enough energy to total a car hood or punch through standard three-tab shingles. Quarter-sized hail can strip crops and leave cosmetic scars on siding and outdoor equipment.
The April 18 storms fit the seasonal pattern, but their precise economic and human cost will not come into focus until the NCEI database and local damage assessments catch up with what the spotters saw on the ground.
