Its all subjective, but snow cover is less overrated than single digits and bare ground imho. If its going to be cold, and no snow is falling there might as well be some on the ground.
WAA is almost always under modeled, hence why during a storm we get the warm nose. It does suck, but there should be enough liquid in the snow / frozen ground underneath / lower sun angle through filtered overcast that we don't lose to much. Its going to compact but whatever refreezes should having some staying power.
