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 52 reports in total: most hail days here are logged from a single spot. 2 of those 17 years produced none at all. One year dominates the record: 2025 alone produced 7 of the 31 days. The last five years have run hotter than the long-run rate: 14 days since 2022, against 1.4 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 2023-06-20. Those big days do not follow the county's usual calendar: most of them fall in June, not May. Golf-ball size is rarer still: 1.75 inches or more on 5 of the 31 days.
