See call-center options ->NOAA's Storm Prediction Center has logged 20 separate hail days here since 2010 -- 1.2 a year over 17 years of record. They carry 34 reports in total: most hail days here are logged from a single spot. 5 of those 17 years produced none at all. The busiest single year was 2016, with 3 hail days. The last five years track the long-run rate, with 4 days since 2022.
Most hail here stays under 2 inches: only 1 of the 20 days on record passed it, 5%, the last on 2015-06-27. Those big days do not follow the county's usual calendar: most of them fall in June, not July. Golf-ball size is rarer still: 1.75 inches or more on 3 of the 20 days.
