1) Pockets of gas are because it's overcarbed relative to your pressure. This makes sense if you carbed at 11 psi and now you're at 8 psi
2) The fact that it's 12 degrees at night is probably the problem. If the temperature gets lower than you think, the beer will absorb a lot more CO2 so it'll continue to be overcarbed compared to your serving pressure.
Turn the pressure back up to 11 psi and try to keep the temperature consistent. I'll add that most fridges aren't designed to work in ambient temperatures that cold. Move the fridge inside, or buy a dual stage temp controller and throw in a light bulb or heating pad.
