See call-center options ->NOAA's Storm Prediction Center has logged 28 separate hail days here since 2010 -- 1.6 a year over 17 years of record. Those days carry 58 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: 2015 alone produced 6 of the 28 days. The last five years track the long-run rate, with 7 days since 2022.
Most hail here stays under 2 inches: only 2 of the 28 days on record passed it, 7%, the last on 2025-07-07. Those big days do not follow the county's usual calendar: most of them fall in July, not June. 9 of the 28 days reached golf-ball size, 1.75 inches or bigger.
