See call-center options ->NOAA's Storm Prediction Center has logged 25 separate hail days here since 2010 -- 1.5 a year over 17 years of record. They carry 41 reports in total: most hail days here are logged from a single spot. 3 of those 17 years produced none at all. The busiest single year was 2013, with 4 hail days. The last five years track the long-run rate, with 8 days since 2022.
3 of the 25 days reached 2 inches or more -- 12%, or about one hail day in 8, the last on 2013-07-22. Those big days do not follow the county's usual calendar: most of them fall in September, not June. Golf-ball size is rarer still: 1.75 inches or more on 6 of the 25 days.
