See call-center options ->NOAA's Storm Prediction Center has logged 13 separate hail days here since 2010 -- 0.8 a year over 17 years of record. Those days carry 25 separate reports between them, two or three on a typical one. 7 of those 17 years produced none at all. The busiest single year was 2025, with 2 hail days. The last five years have run hotter than the long-run rate: 6 days since 2022, against 0.6 a year before that.
