NOAA's radar hail archive holds no records at all for April 19, 2023 and April 20, 2023 (UTC), anywhere in the country, so radar figures for this date are missing. That is a gap in NOAA's processing, not a sign that radar saw no hail.

Spotter reports come from the Storm Prediction Center's preliminary daily logs, grouped here by local calendar date (Central Daylight Time) and by county: a report counts for Chicago when its coordinates fall inside one of the metro's 7 counties (Cook, DuPage, Kane, Lake, McHenry, Will and Kendall counties). Radar signatures are estimates from the Hail Detection Algorithm, not measured stones; they include every cell it rated, from a 10% to a 100% probability of hail. How these pages are built.
