How these figures are built
Reports are NWS Local Storm Reports of hail, pulled from the Iowa Environmental Mesonet archive. This page reads data/hail/events-2026.json (pulled 2026-10-01). Local Storm Reports are preliminary and unverified: sizes are what spotters, the public and emergency managers reported, and NOAA NCEI's Storm Data, published months later, is the verified record. A report with no size counts toward the total but not toward the size figures. Damaging size means 1.5 inches or larger. State is the state named on the report. County is not carried in the archived file; it is assigned here by placing each report's coordinates (rounded to about 1 km) inside US Census cartographic county boundaries, so a report near a county line can land in the neighbouring county. Radar figures are NOAA MRMS MESH, a radar estimate of maximum hail size, not a measurement.
