The archived NWS Local Storm Reports for July 27, 2026 hold 134 hail reports across 12 states. The largest reported stone was 4.50 inches, in Shawano County, Wisconsin. Illinois logged the most reports (71). Report sizes are as people reported them; radar sizes are NOAA estimates.
A storm day runs 7 a.m. to 7 a.m. Central (12:00 to 12:00 UTC), as the Storm Prediction Center counts it, so an evening storm stays on the day it fell. The radar swath covers the UTC calendar day, 7 p.m. Central the evening before to 7 p.m. Central this day.

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 2026-10-20). 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. Radar figures are NOAA MRMS MESH, a radar estimate of maximum hail size, not a measurement.
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
