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. Those days carry 55 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 2014, with 3 hail days. The last five years track the long-run rate, with 8 days since 2022.
Most hail here stays under 2 inches: only 2 of the 27 days on record passed it, 7%, the last on 2024-05-08. Those big days do not follow the county's usual calendar: most of them fall in May, not April.
