I've not really had a problem priming in cold temperatures albeit with 1 caveat; always bring your paints up to comfortable room temp first.
I tend to do all my priming in my garage, which is, for all intents and purposes, the same temperature as the outside world. My primers are also stored there. I identify when I will want to paint and try to bring the primer into the house about an hour before that. Every so often, I'll give the can a good shake during this warming process. Does it help? Who knows; but it can't hurt.
I've never had problems with the finish by prewarming in this way.
Hope that helps.
