See call-center options ->NOAA's Storm Prediction Center has logged 31 separate hail days here since 2010 -- 1.8 a year over 17 years of record. Those days carry 112 separate reports between them, better than three on a typical one. 4 of those 17 years produced none at all. The busiest single year was 2024, with 5 hail days. The last five years have run hotter than the long-run rate: 13 days since 2022, against 1.5 a year before that.
Most hail here stays under 2 inches: only 2 of the 31 days on record passed it, 6%, the last on 2023-04-04. Those big days do not follow the county's usual calendar: most of them fall in April, not May. Golf-ball size is rarer still: 1.75 inches or more on 6 of the 31 days.
