See call-center options ->NOAA's Storm Prediction Center has logged 40 separate hail days here since 2010 -- 2.4 a year over 17 years of record. Those days carry 86 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 2011, with 6 hail days. The last five years track the long-run rate, with 9 days since 2022.
Most hail here stays under 2 inches: only 2 of the 40 days on record passed it, 5%, the last on 2023-05-12. Those big days do not follow the county's usual calendar: most of them fall in May, not June. 12 of the 40 days reached golf-ball size, 1.75 inches or bigger.
