After a cold week, I think it's nice to get a slight warm-up ahead of the approaching storm. The storm will stay to the west of Utah as it drops south this weekend. Moisture wrapped around it will bring a round of mainly light snow.
A cold front will stall out somewhere between SLC and Nephi Friday night into Saturday. Most accumulation will be in the vicinity of the front, outside of that amounts will be pretty light.
Snow will likely taper off in the north by Sunday morning with precipitation moving into Southern Utah late Saturday / Sunday. Rain & snow could linger in the south into early next week.
