See call-center options ->NOAA's Storm Prediction Center has logged 15 separate hail days here since 2010 -- 0.9 a year over 17 years of record. Those days carry 28 separate reports between them, two or three on a typical one. 8 of those 17 years produced none at all. One year dominates the record: 2016 alone produced 4 of the 15 days. The last five years have been quieter than the long run: 2 days since 2022, against 1.1 a year before that.
Roof-killing hail is routine here: 4 of the 15 days reached 2 inches or more, 27% of them, the last on 2026-04-30. Those big days do not follow the county's usual calendar: most of them fall in April, not March. 5 of the 15 days reached golf-ball size, 1.75 inches or bigger.
