See call-center options ->NOAA's Storm Prediction Center has logged 21 separate hail days here since 2010 -- 1.2 a year over 17 years of record. Those days carry 41 separate reports between them, two or three on a typical one. 4 of those 17 years produced none at all. The busiest single year was 2025, with 3 hail days. The last five years have run hotter than the long-run rate: 9 days since 2022, against 1.0 a year before that.
2 of the 21 days reached 2 inches or more -- 10%, or about one hail day in 10, the last on 2017-09-20. Those big days do not follow the county's usual calendar: most of them fall in July, not May. Golf-ball size is rarer still: 1.75 inches or more on 5 of the 21 days.
