For that conditions the skylight wont suit your needs as the vents are not fully closable. That can be quite uncomfortable in snowstorms.
I still don`t know your height, so i wont suggest some of the smaller tents.
For your application (skiing and backpacking) i would try to stay below 3kg or about 7lbs. I think thats already quite a weight for a backpacking tent. Of course there are lots of tents for extreme conditions that are heavier but you wont have that much fun skiing with them in your pack.
For extreme toughness and a well thought-out design as well as a spacious vestibule i´d recommend the
MSR Fury.

Even though thats a really nice tent it would still be to heavy to me. For a little less sturdiness but a little bigger vestibule the Mountain Equipment Dragonfly 2 XT is about 500g lighter.
It´s really difficult to get in the US though.

If you like versatile Tents you should also have a look at the Black Diamond Lighthouse Tent.
It`s sturdy enough for winter storms, large enough for people over 180cm and has an optional vestibule wich adds a lot of space but can be left at home for a really lightweight experience.

I own the Black Diamond Hilight tent and an optional vestibule (and carbon poles by the way
![Grin :D](https://forum.multitool.org/Smileys/default/grin.gif)
) which i use in about the same conditions as you: Wintercamping on high alpine summits.
Its on the small side though and you will have a tough time fitting in there if you are taller than 180cm. Considering you will use a winter Sleeping bag that bag will most likely touch the wally on each side in that tent. You will need a sleeping bag with waterproof outershell in that tent.
If you own such a sleeping bag and are max 180cm tall, that tent might be an option for you.
By the way: Its typical use weight is 1,3kg (or 1,2 with carbon poles

).

The Bibler Tempest would also be a good choice - its just slightly heavy (as the Fury is).
