See call-center options ->NOAA's Storm Prediction Center has logged 38 separate hail days here since 2010 -- 2.2 a year over 17 years of record. Those days carry 107 separate reports between them, two or three on a typical one. 3 of those 17 years produced none at all. One year dominates the record: 2011 alone produced 8 of the 38 days. The last five years have been quieter than the long run: 7 days since 2022, against 2.6 a year before that.
5 of the 38 days reached 2 inches or more -- 13%, or about one hail day in 8, the last on 2023-04-04. They land in the same month as everything else, April. 10 of the 38 days reached golf-ball size, 1.75 inches or bigger.
