See call-center options ->NOAA's Storm Prediction Center has logged 24 separate hail days here since 2010 -- 1.4 a year over 17 years of record. Those days carry 44 separate reports between them, two or three on a typical one. 5 of those 17 years produced none at all. One year dominates the record: 2012 alone produced 5 of the 24 days. The last five years have run hotter than the long-run rate: 10 days since 2022, against 1.2 a year before that.
3 of the 24 days reached 2 inches or more -- 12%, or about one hail day in 8, the last on 2025-05-16. Those big days do not follow the county's usual calendar: most of them fall in March, not April. 8 of the 24 days reached golf-ball size, 1.75 inches or bigger.
