6/17/2013 11:30 AM lost internet with lightning, so couldn't report event at the time. This is the largest hail I've ever (25 yrs) seen up here! Hail came straight down. Rain gauge was measured after the rain stopped. All the rain/hail occurred within 10 minutess 1/2" Grape 1/2" Grape 3/8" Soft|White Ice 3min no damage Continuous False After rain Before smaller hail 4
6/28/2013 6:30 PM Distance between hailstones (large & small) was about 2 inches. No hail pad. Noted large hail stones were clear ice in the center surrounded by white ice. Also appeared that the stone had broken before it hit the ground. None of the large stones were round; it was as though these collided on the way down and split. I was looking at a hail stone cross-section! 5/8" 3/8" 1/4" Pea Size Hard|Clear Ice|White Ice 3 1min no damage Continuous True After rain Same time as smaller hail vertical
