See call-center options ->NOAA's Storm Prediction Center has logged 29 separate hail days here since 2010 -- 1.7 a year over 17 years of record. They carry 49 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 2018, with 3 hail days. The last five years track the long-run rate, with 6 days since 2022.
