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-2023.json (pulled 2026-10-17). 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. Severe size means 1 inch or larger, the National Weather Service threshold. Crops can be hurt by smaller hail, especially with wind, and the loss depends on growth stage: the corn growing point stays below ground until about V6, and leaf loss near tasseling costs the most yield. 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 neighboring county.
Method: one day of hail reports, counted and ranked as filed; county placed by coordinates; severe means 1″ or larger (NWS) · Sources: NWS Local Storm Reports via the Iowa Environmental Mesonet, NOAA MRMS MESH, US Census county boundaries, Assessing Hail Damage to Corn (NCH-1) · Reviewed by Sigurd Lindquist, CCA
