See call-center options ->NOAA's Storm Prediction Center has logged 18 separate hail days here since 2010 -- 1.1 a year over 17 years of record. They carry 31 reports in total: most hail days here are logged from a single spot. 7 of those 17 years produced none at all. One year dominates the record: 2011 alone produced 6 of the 18 days. The last five years have been quieter than the long run: 1 days since 2022, against 1.4 a year before that.
Most hail here stays under 2 inches: only 1 of the 18 days on record passed it, 6%, the last on 2021-03-27. Those big days do not follow the county's usual calendar: most of them fall in March, not May. Golf-ball size is rarer still: 1.75 inches or more on 3 of the 18 days.
