See call-center options ->NOAA's Storm Prediction Center has logged 24 separate hail days here since 2010 -- 1.4 a year over 17 years of record. Those days carry 46 separate reports between them, two or three on a typical one. 5 of those 17 years produced none at all. One year dominates the record: 2011 alone produced 7 of the 24 days. The last five years track the long-run rate, with 5 days since 2022.
5 of the 24 days reached 2 inches or more -- 21%, or about one hail day in 5, the last on 2025-05-20. Those big days do not follow the county's usual calendar: most of them fall in March, not May. 10 of the 24 days reached golf-ball size, 1.75 inches or bigger.
