SOUTH TEXAS / SAN ANTONIO — Southern Texas is the only real severe weather area in the country today, April 30, 2026, with a Level 1 — 5% hail risk flagged for a broad zone covering San Antonio, Austin, New Braunfels, Del Rio, Eagle Pass, Corpus Christi, and surrounding South Texas communities — with hail up to golf ball size or smaller possible during a 3 to 8 p.m. window this afternoon and evening.
Southern Texas Only Real Severe Weather Zone Nationally Today
As the country moves into a quieter stretch of severe weather potential following the active outbreak days earlier this week, southern Texas stands out as the sole area with any meaningful severe weather risk on April 30. Forecasters noted that while the broader pattern is calming down, low-end hail chances remain a daily possibility somewhere in the country during the warmer months — and today that focus falls squarely on the South Texas corridor.
The hail potential is being classified at Level 1 with a 5% probability — a low-end but real threat that warrants awareness for residents and vehicle owners across the affected zone during the afternoon and evening hours.
Hail Up to Golf Ball Size or Smaller — 3 to 8 PM Window
The primary threat from any storms that develop across southern Texas today is hail generally up to golf ball size — approximately 1.75 inches in diameter — or smaller. Golf ball-size hail sits above the severe hail threshold and is capable of causing meaningful damage to vehicles, rooftops, and exposed property if storms fire and produce at the upper end of the forecast range.
The active window for hail-producing storm development is identified as 3 to 8 p.m. — a five-hour window covering the late afternoon through evening hours when daytime heating peaks and storm initiation becomes most likely across the South Texas landscape.
Hail Risk Zone Covers San Antonio Austin Del Rio to Corpus Christi
The hail potential zone on the April 30 outlook map covers a wide swath of South and Central Texas — with the risk area encompassing San Antonio, Austin, New Braunfels, Del Rio, Eagle Pass, Fort Stockton, and Corpus Christi within its boundaries. Communities along major highway corridors connecting these population centers also fall within the broader risk footprint.
Dallas, Fort Worth, Waco, Killeen, Midland, and San Angelo sit outside the primary hail risk zone and are not expected to see significant severe weather activity today.
Quieter Stretch Ahead for Severe Weather Nationally
Today’s low-end South Texas hail threat marks the tail end of what has been an exceptionally active severe weather period across multiple states. Forecasters confirmed the country is moving into a quieter stretch in terms of organized severe weather potential — though low-end localized storm chances will remain in the forecast somewhere across the nation each day as temperatures continue rising through the spring and early summer season.
Residents across the South Texas hail zone should keep an eye on afternoon storm development and consider moving vehicles under cover before the 3 p.m. window opens if golf ball-size hail is a concern for their area. Stay with GordonRamsayClub.com for the latest updates.
