See call-center options ->NOAA's Storm Prediction Center has logged 57 separate hail days here since 2010 -- 3.4 a year over 17 years of record. Those days carry 198 separate reports between them, better than 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 8 hail days. The last five years track the long-run rate, with 16 days since 2022.
9 of the 57 days reached 2 inches or more -- 16%, or about one hail day in 6, the last on 2026-03-10. Those big days do not follow the county's usual calendar: most of them fall in September, not April. 15 of the 57 days reached golf-ball size, 1.75 inches or bigger.
