Those days carry 32 separate reports between them, two or three on a typical one. 7 of those 17 years produced none at all. One year dominates the record: 2024 alone produced 4 of the 15 days. The last five years have run hotter than the long-run rate: 8 days since 2022, against 0.6 a year before that.

2 of the 15 days reached 2 inches or more -- 13%, or about one hail day in 8, the last on 2017-05-28. Those big days do not follow the county's usual calendar: most of them fall in May, not July.
