See call-center options ->NOAA's Storm Prediction Center has logged 26 separate hail days here since 2010 -- 1.5 a year over 17 years of record. They carry 44 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 2012, with 5 hail days. The last five years have run hotter than the long-run rate: 12 days since 2022, against 1.2 a year before that.
Most hail here stays under 2 inches: only 1 of the 26 days on record passed it, 4%, the last on 2012-08-16. Those big days do not follow the county's usual calendar: most of them fall in August, not May. 9 of the 26 days reached golf-ball size, 1.75 inches or bigger.
