We live on Kaneohe Bay and experienced a thunderstorm with hail. The first wave of hail was sized between marble and golf ball in very odd shapes. The second wave was heavier but very uniform, marble-sized hail. There was so much hail during the second wave that it felt like I was standing in front of my freezer with the door open. I could briefly see my breath it was so cold! Very rare for sea-level Oahu to experience this.
