See call-center options ->NOAA's Storm Prediction Center has logged 132 separate hail days here since 2010 -- 7.8 a year over 17 years of record. Those days carry 300 separate reports between them, two or three on a typical one. No year since 2010 has gone by without at least one. The busiest single year was 2019, with 17 hail days. The last five years have been quieter than the long run: 24 days since 2022, against 9.0 a year before that.
