Not sure where in NY the OP is, but here in Southern Ontario,Canada the temperature has dropped this morning to -8 deg C, feeling like -13 deg C with the windchill.
I always keep my guitars, both Electric and Acoustic, in their cases (as much as I would like to keep them out on display and quick reach)with the humipaks in the cases and a constant room temperature in the colder / winter months. I also have a in room humidifier as my finished basement is very dry.
