See call-center options ->NOAA's Storm Prediction Center has logged 18 separate hail days here since 2010 -- 1.1 a year over 17 years of record. Those days carry 43 separate reports between them, two or three on a typical one. 6 of those 17 years produced none at all. One year dominates the record: 2024 alone produced 4 of the 18 days. The last five years track the long-run rate, with 6 days since 2022.
Roof-killing hail is routine here: 6 of the 18 days reached 2 inches or more, 33% of them, the last on 2024-06-13. They land in the same month as everything else, June. More than half of every hail day on record here -- 9 of 18 -- reached golf-ball size, 1.75 inches or bigger.
