This is why 4-season tents have flaps at the bottom, so you can close them with snow and stones. That way your tent doesn't fly away and snow can't be blown inside.
So, if you have wind and snow, get a 4-season. If it's calm, just cold, get a better sleeping bag. It's the sleeping bag that keeps you toasty, not the tent itself.
