See call-center options ->NOAA's Storm Prediction Center has logged 14 separate hail days here since 2010 -- 0.8 a year over 17 years of record. Those days carry 33 separate reports between them, two or three on a typical one. 11 of those 17 years produced none at all. One year dominates the record: 2011 alone produced 4 of the 14 days. The last five years track the long-run rate, with 3 days since 2022.
