See call-center options ->NOAA's Storm Prediction Center has logged 22 separate hail days here since 2010 -- 1.3 a year over 17 years of record. Those days carry 68 separate reports between them, better than three on a typical one. 7 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 1.5 a year before that.
Most hail here stays under 2 inches: only 2 of the 22 days on record passed it, 9%, the last on 2023-06-25. Those big days do not follow the county's usual calendar: most of them fall in April, not March. 9 of the 22 days reached golf-ball size, 1.75 inches or bigger.
