Those days carry 109 separate reports between them, two or three on a typical one. 2 of those 17 years produced none at all. The busiest single year was 2023, with 7 hail days. The last five years have run hotter than the long-run rate: 19 days since 2022, against 2.5 a year before that.
8 of the 49 days reached 2 inches or more -- 16%, or about one hail day in 6, the last on 2024-06-07. Those big days do not follow the county's usual calendar: most of them fall in June, not May. More than half of every hail day on record here -- 25 of 49 -- reached golf-ball size, 1.75 inches or bigger.
