See call-center options ->NOAA's Storm Prediction Center has logged 26 separate hail days here since 2010 -- 1.5 a year over 17 years of record. Those days carry 52 separate reports between them, two or three on a typical one. 2 of those 17 years produced none at all. The busiest single year was 2011, with 5 hail days. The last five years track the long-run rate, with 8 days since 2022.
6 of the 26 days reached 2 inches or more -- 23%, or about one hail day in 4, the last on 2025-04-03. Those big days do not follow the county's usual calendar: most of them fall in March, not April. 9 of the 26 days reached golf-ball size, 1.75 inches or bigger.
