See call-center options ->NOAA's Storm Prediction Center has logged 17 separate hail days here since 2010 -- 1.0 a year over 17 years of record. Those days carry 44 separate reports between them, two or three on a typical one. 9 of those 17 years produced none at all. One year dominates the record: 2011 alone produced 5 of the 17 days. The last five years have been quieter than the long run: 3 days since 2022, against 1.2 a year before that.
3 of the 17 days reached 2 inches or more -- 18%, or about one hail day in 6, the last on 2013-05-29. They land in the same month as everything else, May. Golf-ball size is rarer still: 1.75 inches or more on 4 of the 17 days.
