Free Naperville storm data download
The Naperville dataset on this page — every wind and hail event within about 25 miles of Naperville or recorded for DuPage County from the last 12 months, consolidated so the same source record is never counted twice (a storm that triggered several NWS warning products shows each product), with dates, counties, event types, measured gusts, and hail sizes — downloads free, reusable with attribution under the data license: download CSV · download JSON. Because the radius can cross county and state lines while county records can extend beyond it, these counts can legitimately differ from the DuPage County-only totals above. Statewide files are on the Illinois storm data page.
