See call-center options ->NOAA's Storm Prediction Center has logged 35 separate hail days here since 2010 -- 2.1 a year over 17 years of record. Those days carry 64 separate reports between them, two or three on a typical one. Exactly one year since 2010 passed with no reported hail day at all. The busiest single year was 2010, with 5 hail days. The last five years track the long-run rate, with 9 days since 2022.
6 of the 35 days reached 2 inches or more -- 17%, or about one hail day in 6, the last on 2023-07-18. Those big days do not follow the county's usual calendar: most of them fall in July, not June. 9 of the 35 days reached golf-ball size, 1.75 inches or bigger.
