See call-center options ->NOAA's Storm Prediction Center has logged 29 separate hail days here since 2010 -- 1.7 a year over 17 years of record. Those days carry 63 separate reports between them, two or three on a typical one. 2 of those 17 years produced none at all. The busiest single year was 2022, with 3 hail days. The last five years track the long-run rate, with 7 days since 2022.
Most hail here stays under 2 inches: only 1 of the 29 days on record passed it, 3%, the last on 2012-07-20. 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 5 of the 29 days.
