See call-center options ->NOAA's Storm Prediction Center has logged 27 separate hail days here since 2010 -- 1.6 a year over 17 years of record. They carry 48 reports in total: most hail days here are logged from a single spot. Exactly one year since 2010 passed with no reported hail day at all. The busiest single year was 2012, with 5 hail days. The last five years track the long-run rate, with 6 days since 2022.
Most hail here stays under 2 inches: only 1 of the 27 days on record passed it, 4%, the last on 2011-06-19. Those big days do not follow the county's usual calendar: most of them fall in June, not May. 7 of the 27 days reached golf-ball size, 1.75 inches or bigger.
