I live in Minnesota. You need 3 jackets for winter. Waterproof Medium to heavy shell that has vents. Medium warm jacket (mine is a hooded Columbia omnitech) . A very warm long jacket that goes to at least mid thigh that is windproof.
The last jacket is for when it is below zero - mine is a Eddie bauer expedition parka.
Throw in some hats, gloves and fleece hoodies and you should be good. Dont forget insulated water proof boots, Columbia makes decent ones or sorel
