Provenance
Final counts: NCEI Storm Events Database, file vintage c20260527, hail events with recorded magnitude ≥1.00″ and point coordinates within 35 miles of the Oklahoma City anchor. 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. Spotted an error? Email the address on our terms page and we correct against the source.
