See call-center options ->NOAA's Storm Prediction Center has logged 22 separate hail days here since 2010 -- 1.3 a year over 17 years of record. They carry 32 reports in total: most hail days here are logged from a single spot. 2 of those 17 years produced none at all. The busiest single year was 2023, 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 22 days on record passed it, 5%, the last on 2011-05-25. Those big days do not follow the county's usual calendar: most of them fall in May, not April. Golf-ball size is rarer still: 1.75 inches or more on 5 of the 22 days.
