See call-center options ->NOAA's Storm Prediction Center has logged 18 separate hail days here since 2010 -- 1.1 a year over 17 years of record. They carry 23 reports in total: most hail days here are logged from a single spot. 7 of those 17 years produced none at all. The busiest single year was 2014, with 3 hail days. The last five years track the long-run rate, with 4 days since 2022.
Most hail here stays under 2 inches: only 1 of the 18 days on record passed it, 6%, the last on 2024-02-27. Those big days do not follow the county's usual calendar: most of them fall in February, not July. 5 of the 18 days reached golf-ball size, 1.75 inches or bigger.
