See call-center options ->NOAA's Storm Prediction Center has logged 33 separate hail days here since 2010 -- 1.9 a year over 17 years of record. Those days carry 71 separate reports between them, two or three on a typical one. 2 of those 17 years produced none at all. The busiest single year was 2024, with 4 hail days. The last five years track the long-run rate, with 11 days since 2022.
Most hail here stays under 2 inches: only 1 of the 33 days on record passed it, 3%, the last on 2023-05-08. Those big days do not follow the county's usual calendar: most of them fall in May, not April. Golf-ball size is rarer still: 1.75 inches or more on 6 of the 33 days.
