“Severe thunderstorm winds and hail as large as golf balls caused widespread damage in Norman, particularly in south-central and southwest parts of town. Hundreds of glass window panes at the University of Oklahoma were broken. Car windows were broken, large tree limbs were downed, and two trees were blown over onto a house. The severe winds also toppled a 140-ton crane (with damage estimated at $250,000).”

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.
