See call-center options ->NOAA's Storm Prediction Center has logged 49 separate hail days here since 2010 -- 2.9 a year over 17 years of record. Those days carry 195 separate reports between them, better than three on a typical one. 2 of those 17 years produced none at all. The busiest single year was 2025, with 8 hail days. The last five years have run hotter than the long-run rate: 23 days since 2022, against 2.2 a year before that.
9 of the 49 days reached 2 inches or more -- 18%, or about one hail day in 5, the last on 2025-05-28. Those big days do not follow the county's usual calendar: most of them fall in May, not April. 18 of the 49 days reached golf-ball size, 1.75 inches or bigger.
