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. They carry 36 reports in total: most hail days here are logged from a single spot. 3 of those 17 years produced none at all. The busiest single year was 2026, with 3 hail days. The last five years track the long-run rate, with 8 days since 2022.
Most hail here stays under 2 inches: only 2 of the 22 days on record passed it, 9%, the last on 2026-04-13. 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 5 of the 22 days.
