See call-center options ->NOAA's Storm Prediction Center has logged 27 separate hail days here since 2010 -- 1.6 a year over 17 years of record. Those days carry 50 separate reports between them, two or three on a typical one. 4 of those 17 years produced none at all. The busiest single year was 2012, with 5 hail days. The last five years have been quieter than the long run: 2 days since 2022, against 2.1 a year before that.
Most hail here stays under 2 inches: only 2 of the 27 days on record passed it, 7%, the last on 2019-07-03. Those big days do not follow the county's usual calendar: most of them fall in July, not June. Golf-ball size is rarer still: 1.75 inches or more on 5 of the 27 days.
