See call-center options ->NOAA's Storm Prediction Center has logged 28 separate hail days here since 2010 -- 1.6 a year over 17 years of record. Those days carry 95 separate reports between them, better than three on a typical one. 4 of those 17 years produced none at all. One year dominates the record: 2011 alone produced 6 of the 28 days. The last five years track the long-run rate, with 8 days since 2022.
6 of the 28 days reached 2 inches or more -- 21%, or about one hail day in 5, the last on 2024-03-14. Those big days do not follow the county's usual calendar: most of them fall in March, not April. 13 of the 28 days reached golf-ball size, 1.75 inches or bigger.
