See call-center options ->NOAA's Storm Prediction Center has logged 28 separate hail days here since 2010 -- 1.6 a year over 17 years of record. Those days carry 63 separate reports between them, two or three on a typical one. 3 of those 17 years produced none at all. The busiest single year was 2011, with 4 hail days. The last five years have been quieter than the long run: 4 days since 2022, against 2.0 a year before that.
3 of the 28 days reached 2 inches or more -- 11%, or about one hail day in 9, the last on 2013-06-26. Those big days do not follow the county's usual calendar: most of them fall in May, not June. Golf-ball size is rarer still: 1.75 inches or more on 6 of the 28 days.
