Hailstorms can happen in the middle of July, usually accompanied by a twister. Anyhoo, I'm positive a hailstone the size of a softball would whack him. Even small hailstones hurt when they hit ya

. I would know, for I was outside on a warm day a couple of years ago when the sky suddenly darkened and hail the size of golfballs came down. I managed to get inside quickly but not without being pelted by some, and it stings and hurts :!. Maybe around golfball size would be ideal.
