Source: NCEI Storm Events Database, vintage c20260918, hail events with magnitude ≥1.00″. NWS records are point and path observations. The absence of a nearby report does NOT prove that no hail fell at this address — it means no observation was logged nearby. A report of nearby hail documents the event; it does not by itself prove damage to a specific structure.
