use some of these:
1. god and goddess (wicca/paganism)
2. latobius (celtic god of the sky)
3. Theia (greek goddess of the clear sky)
thats all i could find.
even if you dont use a deity, it is fine. Being bland can do the trick.
you could say " gods and goddesses of the sky's and weather." instead of reffering to one diety.
the first one has always worked better in my opinion.
