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 59 separate reports between them, two or three on a typical one. 7 of those 17 years produced none at all. One year dominates the record: 2019 alone produced 7 of the 26 days. The last five years have been quieter than the long run: 1 days since 2022, against 2.1 a year before that.
Most hail here stays under 2 inches: only 1 of the 26 days on record passed it, 4%, the last on 2020-07-11. Those big days do not follow the county's usual calendar: most of them fall in July, not April. 7 of the 26 days reached golf-ball size, 1.75 inches or bigger.
