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 51 reports in total: most hail days here are logged from a single spot. 3 of those 17 years produced none at all. The busiest single year was 2019, with 4 hail days. The last five years have been quieter than the long run: 5 days since 2022, against 2.2 a year before that.
