See call-center options ->NOAA's Storm Prediction Center has logged 17 separate hail days here since 2010 -- 1.0 a year over 17 years of record. Those days carry 32 separate reports between them, two or three on a typical one. 8 of those 17 years produced none at all. One year dominates the record: 2015 alone produced 5 of the 17 days. The last five years track the long-run rate, with 4 days since 2022.
Most hail here stays under 2 inches: only 1 of the 17 days on record passed it, 6%, the last on 2023-06-12. Those big days do not follow the county's usual calendar: most of them fall in June, not July. Golf-ball size is rarer still: 1.75 inches or more on 4 of the 17 days.
