When I was in the middle of a hail storm, the sky was bright yellow. The temperature outside was hot but with a really cold breeze. It was around July. It was really sudden, and we lived in a trailer at the time so it sounded extremely frightening on the tin roof. The ice ball size was around the size of a softball, and my mum's boyfriend went out in it and got bruised by them pretty bad, so I assume it hurts pretty bad.
