What I teach here is to find a natural shelter in a "microclimate" as Ron Hood puts it. In my area this would be a rock face or an overhang out of the wind on a north facing slope out of the cold airflow that comes down off the mountains. This in itself will get you out of the wind and rain and can then be improved with natural materials or resources that you carry.
I carry, in addition to my bivy and poncho, a clear plastic 2x3 meter droploth and plenty of duct tape. Such an item is worth its weight in gold when constructing an emergency shelter. It will save loads of time and result in a waterproof roof over your head.
A larger enclosed shelter would be a viable option in a very cold climate as long as you had a heat source other than body heat. That means you have to be able to move your fire inside and have an outlet for the smoke. The lean-to relies on reflected heat from a fire. A total enclosure will do that as well as trap warm air and your smoke as well.
One of the keys in the situation you describe is that your clothing must be able to dry. A well made debris shelter will be little use to someone soaked to the skin. A lean-to is the better option in such a situation as it will allow you to get dry. Your first line of insulation is your clothes, a shelter just takes the pressure off of them allowing your clothes to insulate you in better conditions (ie above freezing as opposed to below). If you are wet that won't happen and you will go hypothermic. Could you lie out damp in 40 degree weather? I couldn't, and that is a pretty optomistic result of a well made debris shelter in cold weather. If you are dry and dressed for winter then lying still in 40 degree air is doable.
I would start with a lean-to and then close it off as much as possible to cut out drafts, insulate the floor very thick, site the fire well with a reflector behind it. If that doesn't get you through the week you are in serious trouble. Mac
