Spotter reports come from the Storm Prediction Center's preliminary daily logs, grouped here by local calendar date (Central Daylight Time) and by county: a report counts for San Antonio when its coordinates fall inside one of the metro's 8 counties (Bexar, Comal, Guadalupe, Kendall, Medina, Wilson, Atascosa and Bandera counties). Radar signatures are estimates from the Hail Detection Algorithm, not measured stones; they include every cell it rated, from a 10% to a 100% probability of hail. How these pages are built.
