Actually electronics work better when they are colder. Thats why think its something mechanical. Since your images are overexposed I would suspect the aperture mechanism is actually freezing up, it may very well be happening in your lens since this is the most exposed to the cold and it has lubricant on the aperture which would get very dense in cold temperatures.

a good way to test if that is the problem is go into aperture priority mode on your camera and open the apeture all the way up, so that the camera does not have to stop it down anymore. If your exposure is then correct then you can be pretty sure its the lens mechanics.  Next try another lens and see if the problem is the same.
