See call-center options ->NOAA's Storm Prediction Center has logged 23 separate hail days here since 2010 -- 1.4 a year over 17 years of record. Those days carry 56 separate reports between them, two or three on a typical one. 4 of those 17 years produced none at all. One year dominates the record: 2011 alone produced 6 of the 23 days. The last five years track the long-run rate, with 5 days since 2022.
Most hail here stays under 2 inches: only 2 of the 23 days on record passed it, 9%, the last on 2015-06-21. Those big days do not follow the county's usual calendar: most of them fall in June, not April. 7 of the 23 days reached golf-ball size, 1.75 inches or bigger.
