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 40 separate reports between them, better than three on a typical one. 8 of those 17 years produced none at all. One year dominates the record: 2012 alone produced 3 of the 13 days. The last five years have been quieter than the long run: 1 days since 2022, against 1.0 a year before that.
2 of the 13 days reached 2 inches or more -- 15%, or about one hail day in 6, the last on 2023-04-04. They land in the same month as everything else, April. 6 of the 13 days reached golf-ball size, 1.75 inches or bigger.
