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 60 separate reports between them, two or three on a typical one. 5 of those 17 years produced none at all. The busiest single year was 2011, with 5 hail days. The last five years have been quieter than the long run: 2 days since 2022, against 2.0 a year before that.
Roof-killing hail is routine here: 7 of the 26 days reached 2 inches or more, 27% of them, the last on 2026-04-17. Those big days do not follow the county's usual calendar: most of them fall in April, not May. 11 of the 26 days reached golf-ball size, 1.75 inches or bigger.
