there are cycling specific winter jerseys/jackets for winter riding. rear pockets, reflective panels, vents where it counts, long back, etc.
ski/snowboard jackets are way overkill and not very appropriately cut... do a quick search for winter cycling jacket or jersey and check the normal outlets to get an idea of what's out there. i ride this gore jacket with a tee and thermal underneath in up to 30 degree F; loose the tee and add a sweatshirt when it's colder. that + my cannondale balaclava, windproof cycling gloves and a neckwarmer, and my upper body is toasty all winter long (underarm and chest vents keep you from getting too hot).
