See call-center options ->NOAA's Storm Prediction Center has logged 15 separate hail days here since 2010 -- 0.9 a year over 17 years of record. They carry 24 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: 2019 alone produced 3 of the 15 days. The last five years have been quieter than the long run: 2 days since 2022, against 1.1 a year before that.
Most hail here stays under 2 inches: only 1 of the 15 days on record passed it, 7%, the last on 2020-07-06. Those big days do not follow the county's usual calendar: most of them fall in July, not May. Golf-ball size is rarer still: 1.75 inches or more on 3 of the 15 days.
