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 61 separate reports between them, two or three on a typical one. 5 of those 17 years produced none at all. The busiest single year was 2013, 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.
3 of the 29 days reached 2 inches or more -- 10%, or about one hail day in 10, the last on 2026-05-15. Those big days do not follow the county's usual calendar: most of them fall in August, not April. Golf-ball size is rarer still: 1.75 inches or more on 7 of the 29 days.
