See call-center options ->NOAA's Storm Prediction Center has logged 23 separate hail days here since 2010 -- 1.4 a year over 17 years of record. They carry 35 reports in total: most hail days here are logged from a single spot. 5 of those 17 years produced none at all. One year dominates the record: 2010 alone produced 5 of the 23 days. The last five years track the long-run rate, with 7 days since 2022.
