See call-center options ->NOAA's Storm Prediction Center has logged 29 separate hail days here since 2010 -- 1.7 a year over 17 years of record. Those days carry 94 separate reports between them, better than three on a typical one. 3 of those 17 years produced none at all. The busiest single year was 2022, with 5 hail days. The last five years have run hotter than the long-run rate: 12 days since 2022, against 1.4 a year before that.
7 of the 29 days reached 2 inches or more -- 24%, or about one hail day in 4, the last on 2025-09-21. Those big days do not follow the county's usual calendar: most of them fall in May, not June. 12 of the 29 days reached golf-ball size, 1.75 inches or bigger.
