See call-center options ->NOAA's Storm Prediction Center has logged 18 separate hail days here since 2010 -- 1.1 a year over 17 years of record. Those days carry 42 separate reports between them, two or three on a typical one. 6 of those 17 years produced none at all. One year dominates the record: 2025 alone produced 4 of the 18 days. The last five years have run hotter than the long-run rate: 9 days since 2022, against 0.8 a year before that.
4 of the 18 days reached 2 inches or more -- 22%, or about one hail day in 4, the last on 2025-05-15. Those big days do not follow the county's usual calendar: most of them fall in March, not May. 6 of the 18 days reached golf-ball size, 1.75 inches or bigger.
