See call-center options ->NOAA's Storm Prediction Center has logged 55 separate hail days here since 2010 -- 3.2 a year over 17 years of record. Those days carry 126 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 2016, with 8 hail days. The last five years have run hotter than the long-run rate: 23 days since 2022, against 2.7 a year before that.
Roof-killing hail is routine here: 14 of the 55 days reached 2 inches or more, 25% of them, the last on 2026-04-23. Those big days do not follow the county's usual calendar: most of them fall in April, not May. 21 of the 55 days reached golf-ball size, 1.75 inches or bigger.
