Weather Magic

Weather magic would probably have huge impacts on the environment. This is because to create a snowstorm in a dessert for example you would have to get that moisture from somewhere. There are two ways to get the water that I can think of 1 they gather the water from nearby which would drain the environment (especially in a dessert). The second way is to create the water which would brake the laws of conservation of matter. We already encounter all of these problems without even mentioning all the problems in terms of wind and temperature this would cause.
