Last May was a busy month in Oklahoma. They were tracking a tornado across sw Oklahoma. It was traveling across pastures, quarter mile wide, on the ground for 15 minutes. And the cattle just kept grazing as the tornado passed by.
Many of those storms come with baseball size hail and many of the t.v. news stormchasers were turned back by the hail.
In the old Zane Grey books he talks about storms so charged with electricity that a horse's mane would crackle and the hail would KO and kill cattle. I think that, in the Texas panhandle, these were the storms that spawned (or were) tornadoes.
