Orrrrrr, there are always tons of cosmic rays of the type that create lightning hitting earth, there just aren't the conditions necessary for those rays to trigger lightning except for when there's a big storm. I imagine the clouds are a different electrical environment than a regular sky and maybe in those conditions a cosmic rays will trigger lightning. Like a gigantic bubble chamber made of our atmosphere.
