See call-center options ->NOAA's Storm Prediction Center has logged 24 separate hail days here since 2010 -- 1.4 a year over 17 years of record. They carry 37 reports in total: most hail days here are logged from a single spot. 2 of those 17 years produced none at all. One year dominates the record: 2011 alone produced 6 of the 24 days. The last five years track the long-run rate, with 7 days since 2022.
3 of the 24 days reached 2 inches or more -- 12%, or about one hail day in 8, the last on 2026-04-27. Those big days do not follow the county's usual calendar: most of them fall in April, not May. Golf-ball size is rarer still: 1.75 inches or more on 5 of the 24 days.
