See call-center options ->NOAA's Storm Prediction Center has logged 35 separate hail days here since 2010 -- 2.1 a year over 17 years of record. They carry 52 reports in total: most hail days here are logged from a single spot. 6 of those 17 years produced none at all. One year dominates the record: 2016 alone produced 7 of the 35 days. The last five years have been quieter than the long run: 5 days since 2022, against 2.5 a year before that.
4 of the 35 days reached 2 inches or more -- 11%, or about one hail day in 9, the last on 2020-07-17. Those big days do not follow the county's usual calendar: most of them fall in June, not July. Golf-ball size is rarer still: 1.75 inches or more on 8 of the 35 days.
