Hail days by county since 1955
Sorted by hail days on record. “Since 2015” is the same window the by-county table on /press uses. A county with no qualifying report reads 0, not “no hail”: NOAA records a report only where an observer measured one.

- NOAA files Storm Events hail reports by county, so the county is NOAA's own attribution — not a radius around a point.
- NOAA publishes these ground reports months after a storm, so a recent storm may not be listed yet; the radar record on each city page is current within hours.
- A hail day says hail was reported somewhere in the county that day. It does not say a particular property was hit, and it is not a damage finding.
