See call-center options ->NOAA's Storm Prediction Center has logged 47 separate hail days here since 2010 -- 2.8 a year over 17 years of record. Those days carry 107 separate reports between them, two or three on a typical one. 3 of those 17 years produced none at all. The busiest single year was 2023, with 7 hail days. The last five years track the long-run rate, with 17 days since 2022.
8 of the 47 days reached 2 inches or more -- 17%, or about one hail day in 6, the last on 2024-06-07. Those big days do not follow the county's usual calendar: most of them fall in June, not May. More than half of every hail day on record here -- 24 of 47 -- reached golf-ball size, 1.75 inches or bigger.
