You can't control the elements; therefore, you can't control the weather. This is most likely a mere coincidence.
However, you can make prayers to the entities that do control the weather to make changes, but this comes with very serious consequences for such alterations to the natural order of nature. But that is IF your prayers, pleas, or what ever label you would like to call them are answered. Put it this way: if it's raining in Area A, but not in Area B there's a really good reason for that. If you ask for Area B to get rain, that rain would come from Area A - if said prayer is answered and granted - then A would be without rain that is truly needed there, whereas in B it's not needed as people say it is but is given the rain from Area A.
