Hello BD! Whadya know? I've been looking for magnolia notes myself. I don't have them yet but I'm after Chelsea Flower #9 by Bond New York and Love in White by Creed. Neither of them have a rain/ozone note but I can recommend Demeter Fragrance Library's "Rain" which I've been known to layer with the occasional floral. Rain is a bit sweet and I find it interesting with a non-powdery clear floral, and sometimes on it's own. This is where I'm starting. Welcome to the search!
