See call-center options ->NOAA's Storm Prediction Center has logged 16 separate hail days here since 2010 -- 0.9 a year over 17 years of record. Those days carry 38 separate reports between them, two or three on a typical one. 6 of those 17 years produced none at all. The busiest single year was 2023, with 3 hail days. The last five years track the long-run rate, with 6 days since 2022.
Roof-killing hail is routine here: 4 of the 16 days reached 2 inches or more, 25% of them, the last on 2025-05-15. Those big days do not follow the county's usual calendar: most of them fall in May, not March. 5 of the 16 days reached golf-ball size, 1.75 inches or bigger.
