See call-center options ->NOAA's Storm Prediction Center has logged 15 separate hail days here since 2010 -- 0.9 a year over 17 years of record. They carry 23 reports in total: most hail days here are logged from a single spot. 8 of those 17 years produced none at all. One year dominates the record: 2012 alone produced 3 of the 15 days. The last five years track the long-run rate, with 5 days since 2022.
Most hail here stays under 2 inches: only 1 of the 15 days on record passed it, 7%, the last on 2015-08-02. Those big days do not follow the county's usual calendar: most of them fall in August, not July. 6 of the 15 days reached golf-ball size, 1.75 inches or bigger.
