Replying to Snowbird weather for next weekend

I’m going to snowbird next weekend and don’t know if I should bring my skis (faction ct 2.0) or rent wider skis for more snow. Looking at the weather right now it says their supposed to get like 20 inches from now until I get their and like another foot or more when I get there. Do you think I would have good time without powder skis? Idk if it is even worth it to rent powder skis. Never really skied in that much powder and I don’t know how it works.
