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. Those days carry 43 separate reports between them, two or three on a typical one. 6 of those 17 years produced none at all. One year dominates the record: 2024 alone produced 6 of the 22 days. The last five years track the long-run rate, with 8 days since 2022.
3 of the 22 days reached 2 inches or more -- 14%, or about one hail day in 7, the last on 2019-06-05. Those big days do not follow the county's usual calendar: most of them fall in June, not May. 6 of the 22 days reached golf-ball size, 1.75 inches or bigger.
