See call-center options ->NOAA's Storm Prediction Center has logged 24 separate hail days here since 2010 -- 1.4 a year over 17 years of record. Those days carry 48 separate reports between them, two or three on a typical one. 9 of those 17 years produced none at all. One year dominates the record: 2011 alone produced 9 of the 24 days. The last five years track the long-run rate, with 6 days since 2022.
Roof-killing hail is routine here: 7 of the 24 days reached 2 inches or more, 29% of them, the last on 2024-05-26. They land in the same month as everything else, April. More than half of every hail day on record here -- 12 of 24 -- reached golf-ball size, 1.75 inches or bigger.
