I've only ever heard "Il pleut comme vache qui pisse" without the "une" (which isn't grammatically correct, but I guess it comes from a time when it was). I've heard both expressions no matter the region, it's mostly a matter of wether or not you're talking about time with people ready to discuss bovine pee.
