See call-center options ->NOAA's Storm Prediction Center has logged 31 separate hail days here since 2010 -- 1.8 a year over 17 years of record. They carry 50 reports in total: most hail days here are logged from a single spot. Exactly one year since 2010 passed with no reported hail day at all. The busiest single year was 2024, with 5 hail days. The last five years have run hotter than the long-run rate: 12 days since 2022, against 1.6 a year before that.
Most hail here stays under 2 inches: only 2 of the 31 days on record passed it, 6%, the last on 2020-04-08. Those big days do not follow the county's usual calendar: most of them fall in April, not May. Golf-ball size is rarer still: 1.75 inches or more on 4 of the 31 days.
