Thank you everyone for the needed advice, staring with a larger minion was absolutely needed, I think moving forward with the rest of my Weber charcoal I will double the minion method started from 4 to 8 if it is below 35 degrees.
I started the 6 briquettes at 10 pm, meat went on at 11 pm, pit was reading at 230 before the meat went on. Pit dropped to 140.Took until 1 am to get to 245. Went to bed at 130 am after pit was stable at 245 for over half an hour. Was at 285 at 3 am, sprayed the meat and adjusted the vents. Every hour until 8 am stayed right between 245 and 250. At 8 am reading 210, realized charcoal was running low, did the hot squat pushed lit coals to the one side added new unlit briquettes, opened all vents. By 9 am back to temp reset vents, double foiled the shoulder and back on the pit. Just come off and resting now in the cooler until dinner.
The wind has been nasty, but I think putting up the door as a third side barrier really help keep the wind from having to much of an impact. I think it would have been a different experience without your insight and insistence Lew!
Now this was the first time I had to add more Weber Briquettes on a pork shoulder cook, I ran empty water pan, but I think the cold just caused it to use more fuel which I was ready and able to handle.
Here is at 1 am
Here is at 9 am getting ready to be wrapped
