This is a good example of people who haven't read the novels thinking they know what happen in the novels. The rain clouds were already there and Kakashi was in the process of falling through them. He uses Purple Lightning only to stimulate the rain clouds into producing rain.

I won't vouch for the novels being entirely consistent with the anime or manga, or even with other novels, but use a better example in the future. Sakura Hiden is pretty garbage, so try that if you want.
