Preliminary National Weather Service reports via the NOAA Storm Prediction Center. Record last changed October 17, 2026; latest storm day listed September 11, 2026.
What Counts As A Storm Day
A storm day is one Storm Prediction Center report date with at least one hail report of 1 inch or larger in 8 San Antonio metro counties (Bexar, Comal, Kendall, Guadalupe, Bandera, Medina, Wilson, Atascosa). Storm Prediction Center days run from 12:00 UTC to 12:00 UTC, so a report timed 00:00 to 11:59 UTC belongs to the date before it: the previous evening in Texas. These reports are preliminary. The National Weather Service later reviews them for the NCEI Storm Events record, which is what the San Antonio hail history counts, so a day can be listed here before the NCEI record has it.
A day gets its own page when a stone of 1.75 inches or larger was reported, or at least three reports came in; thinner days are listed here without a page.
