See call-center options ->NOAA's Storm Prediction Center has logged 14 separate hail days here since 2010 -- 0.8 a year over 17 years of record. Those days carry 26 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: 2011 alone produced 3 of the 14 days. The last five years track the long-run rate, with 3 days since 2022.
3 of the 14 days reached 2 inches or more -- 21%, or about one hail day in 5, the last on 2024-05-07. Those big days do not follow the county's usual calendar: most of them fall in September, not April. 6 of the 14 days reached golf-ball size, 1.75 inches or bigger.
