See call-center options ->NOAA's Storm Prediction Center has logged 59 separate hail days here since 2010 -- 3.5 a year over 17 years of record. Those days carry 191 separate reports between them, better than three on a typical one. Exactly one year since 2010 passed with no reported hail day at all. The busiest single year was 2022, with 10 hail days. The last five years track the long-run rate, with 22 days since 2022.
8 of the 59 days reached 2 inches or more -- 14%, or about one hail day in 7, the last on 2024-06-12. Those big days do not follow the county's usual calendar: most of them fall in July, not June. Golf-ball size is rarer still: 1.75 inches or more on 14 of the 59 days.
