It gets extremely cold and very dry here in the winter with relative humidity levels sometimes down into the 60's. I have heard it expressed that because it is so dry, it is possible for the moisture content of wood to drop, or in other words, for the wood to dry out over the winter months. The only difficulty I have with this is that I would think that if the moisture content in the wood is frozen, it cannot be removed from the wood ? On the other hand, I have seen circumstances where I've had snow or ice in my unheated garage and with no access to wind etc. and over the course of a few days the ice or snow will "disappear", therefore I assume it has evaporated. Same thing as if you leave ice cubes in the freezer long enough, eventually they start to lose mass. Any of you more scientific types out there care to express an opinion? Willhound.
