The last five years have been quieter than the long run: 3 days since 2022, against 1.2 a year before that.
2 of the 18 days reached 2 inches or more -- 11%, or about one hail day in 9, the last on 2015-07-14. Those big days do not follow the county's usual calendar: most of them fall in June, not March. 7 of the 18 days reached golf-ball size, 1.75 inches or bigger.
