This movie was set in italy or spain I think' It's about a girl in it that was suppose to join the order to become a nun, but she deviates and somewhat becomes a singer/harlot. The whole time she's gone it doesn't rain and the statue of the lady saint that everyone prays to cries.It not until the end of the movie that the girl returns and join the order that it rains.

Sounds like The Miracle (http://en.wikipedia.org/wiki/The_Miracle_%281959_film%29). Or one of it's remakes.
