NOAA's Storm Prediction Center has logged 22 separate hail days here since 2010 -- 1.3 a year over 17 years of record. Those days carry 69 separate reports between them, better than three on a typical one. 6 of those 17 years produced none at all. One year dominates the record: 2011 alone produced 5 of the 22 days. The last five years have been quieter than the long run: 4 days since 2022, against 1.5 a year before that.
Most hail here stays under 2 inches: only 2 of the 22 days on record passed it, 9%, the last on 2012-07-26. Those big days do not follow the county's usual calendar: most of them fall in May, not April. Golf-ball size is rarer still: 1.75 inches or more on 4 of the 22 days.
