WOW... That's a lot of snow!!! Keep your neck warm. I like to wear a hoodie under those, I pull the strings so it's tight around my neck but not on my head.
OK... Here are my layers, 2 pair of socks, tights/ thermal underware, sweatpants, long sleeve t-shirt, t-shirt, Hoodie, jumpsuit. I don't like wearing jeans under the jumpsuit because it's harder to move in it.
Then you just need hat, gloves, boots!!! You're good to go!!!
