As previously stated, these types of spells do not work. I recommend looking into Starting out and The Basics in General Info to get an understanding of Magick and how it works. Any type of spell that promises to influence the elements, physically change you, give you powers, or anything of that sort will not work.
Kaayus, yes, very wrong! Not everything is possible by magic. You will never grow wings and fly. You will never grow extra legs or arms, two heads. No matter how many spells you cast you will never be anything other than human.
Of course, you may believe anything you wish; but a belief does not make it true!
Kaayus, while it is nice to believe that we can do anything with magic the fact is that magic does have its limits. There are many things that magic cannot accomplish and creating a storm out of nothing would be one of these things.
If you'd like to learn more about what magic can and cannot do I'd suggest these books:
"Real Magic" by Isaac Bonewits
"Spells And How They Work" by Janet and Stewart Farrar
You cannot create or control storms or the weather. You going against nature. You might be able to influence it or manipulate the weather. But you would need a lots of meditation and energy manipulation practice. But as others says you can't just create storms out of the blue.
