Cold weather chain lube?
This can be a regional thing, but here in Germany, many are happy with Ballistol applied as aerosol and not changed during the seasons. 

From a material science perspective, its viscosity is very low and has little temeprature dependence. It is also said that it is environmently friendly, to the extend that you can use it on pets, which I never tried as I found chains on my bike much more suitable.
