A claim file needs the per-address record: every recorded event within 1, 3 and 10 miles of the property, distances, official narratives, and citations an adjuster can check line by line. That's the report — generated in seconds, hosted on HailEvidence (the neutral evidence surface), formatted as an insurance-appeal attachment.

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 St. Louis 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.
