See call-center options ->NOAA's Storm Prediction Center has logged 26 separate hail days here since 2010 -- 1.5 a year over 17 years of record. Those days carry 48 separate reports between them, two or three on a typical one. 3 of those 17 years produced none at all. One year dominates the record: 2022 alone produced 6 of the 26 days. The last five years have run hotter than the long-run rate: 13 days since 2022, against 1.1 a year before that.
Most hail here stays under 2 inches: only 2 of the 26 days on record passed it, 8%, 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 4 of the 26 days.
