6/4/2015 6/05/2015 11:00 PM 2 1.29 M M It hailed pretty hard here about 6:45 pm for 7 minutes. Unfortunately my hail pas was not placed securely and it blew over. I did save 2 of the larger hail balls which represented about 10% of all the hail that fell. It came out of the south in strong gusts. The larger hailstones hit so hard they shattered. The two I retrieved were each about 2 cm diameter. Together they weighed 9 grams.
