See call-center options ->NOAA's Storm Prediction Center has logged 19 separate hail days here since 2010 -- 1.1 a year over 17 years of record. They carry 26 reports in total: most hail days here are logged from a single spot. 8 of those 17 years produced none at all. One year dominates the record: 2013 alone produced 4 of the 19 days. The last five years track the long-run rate, with 4 days since 2022.
2 of the 19 days reached 2 inches or more -- 11%, or about one hail day in 10, the last on 2022-06-16. Those big days do not follow the county's usual calendar: most of them fall in June, not May. 5 of the 19 days reached golf-ball size, 1.75 inches or bigger.
