See call-center options ->NOAA's Storm Prediction Center has logged 24 separate hail days here since 2010 -- 1.4 a year over 17 years of record. Those days carry 52 separate reports between them, two or three on a typical one. 6 of those 17 years produced none at all. One year dominates the record: 2019 alone produced 6 of the 24 days. The last five years track the long-run rate, with 8 days since 2022.
