See call-center options ->NOAA's Storm Prediction Center has logged 36 separate hail days here since 2010 -- 2.1 a year over 17 years of record. Those days carry 70 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 2019, with 4 hail days. The last five years have been quieter than the long run: 7 days since 2022, against 2.4 a year before that.
Most hail here stays under 2 inches: only 3 of the 36 days on record passed it, 8%, the last on 2021-07-09. Those big days do not follow the county's usual calendar: most of them fall in March, not June. Golf-ball size is rarer still: 1.75 inches or more on 5 of the 36 days.
