I'm gonna go out on a limb here and say that a product that is designed to ski on frozen water can handle a good bit of time in the cold.
I would bet that the skis, like ski boots get exercised more from the exrtemes they go through than being in one environment than the other.
They get some version of:
Take them from the basement (45~55 deg), then possibly a car rack or trunk (varies, ski rack would be the coldest with the induced wind chill = single digits or negative), then ski on a frozen surface, leave them in the lodges ski rack while you take a break (could be same as cars ski rack), and eventually reverse the process until the skis are back in the basement.
The skis are seeing a variation of at least 50 degrees and could be as much as 70 if stored in a warmer area and again more if skied on a colder day.
All the pieces on a ski has their own co-efficient of thermal expansion (CTE) causing each to expand and contract at a different rate. This is what usually fatigues things the most.
The skis are probably better off always being out side and not coming inside.
As for the bases themselves, I think the only thing that would harm them outside is using them.
