“Large hail broke car windows, damaged roofs and stripped trees and at least 3,000 acres of crops. At Eaton's high school, middle school and two elementary schools, at least 60 skylights were shattered by hail. Water flooded the hallways and classrooms. Damage to the schools alone was estimated at $2 million.”

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 Denver 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.
