Devil's advocate. What is your climate like in the off season? Ever thought about non-winter adventures?
Listen to these people with experience camping in all sorts of weather and save yourself a lot of misery. There are years of history here of people getting it right... and getting it wrong. The universal truth is seal it up tight against water damage, but ventilate for comfort and against moisture build up.
On the subject of cross ventilation, best plan is to bring fresh air in at floor or mattress level and vent out at roof high point or top of wall. Heat rises and creates natural chimney convection. CO2 sinks. If your cross flow/updraft is not adequate to lift the CO2 out, having a low intake will let it sink out (at least that's how I figure it).
One more thing (for now at least... and we have heard this so many times), don't be afraid of curves instead of hard miters. At least plan on large radii at joints. Igloos don't cave in from snow load because they are dome shaped, and eskimos have few tools to work with, so how hard can it be? Consider GPW's Foamstream build method. Plenty of arch structure, aero, good wind spillage, headroom, etc.
Okay, one more thought. Don't worry about snow load lifting or lowering a popup. You will be carrying one of those telescoping trucker rakes used to remove snow from your roof. (period)... and be clearing snow off accordingly. It's the law here, I assume there, too.
