Actually, jeans are about the worst clothing you can wear in wet and inclement weather. I'm allowed to wear (tidy) jeans for work, but snowy weather is about the one time I don't wear them. Once wet, denim becomes heavy and does not dry very quickly. That's why you never see experienced outdoor people wearing them. A cotton/polyester weave fabric, or maybe corderouy, is about the best fabric for such conditions. Not exactly high fashion, I know, but certainly more practical.
