4 of the 19 days reached 2 inches or more -- 21%, or about one hail day in 5, the last on 2023-07-19. Those big days do not follow the county's usual calendar: most of them fall in July, not May. More than half of every hail day on record here -- 10 of 19 -- reached golf-ball size, 1.75 inches or bigger.
