I'm afraid I dont have a recommendation for rain gear that goes over your gear but I have Klim jacket and pants and they are DEFIANTLY storm proof. All you have to do is zip closed the vents and I rode through storms in Tasmania so heavy all I could see were blury tail lights. My cousin had rain gear that went over the top of his gear and came out soaked. Nothing got through my Klim gear. Most guys I know go the cheap over the top gear and I'm not saying Oxford gear falls in that category (I'm sure decent over the top wet weather gear will keep you dry) and once they end up in wet weather they find out the cheap stuff is a waste of time and money. I can definitely say klim jacket and pants and knox wet weather gloves work.
