I live in a Texas and usually only smoke meat during good weather, however we have an office Christmas party coming up and have volunteered to smoke the meat. I will be cooking a small brisket (10 lbs) and a pork shoulder about the same size, the day of the party looks cold (for this area). I know it takes longer in cold weather than warm, just curious if any of you can quantify it? Like on cold days add 2 hrs to planned cooking time. Thanks!
