I'm preparing to do my first brisket this weekend for a christmas party on Saturday at 6pm. Well it looks like the weather has turned south on me, and it going to be in the high 20s. I'm smoking a 6 pounder, and I figured if I fired the smoker up at 6am I wouldn't have any trouble completing the task by 6pm. I'm going to use the basic brisket smoke method. I'm smoking on a Horizon. Will I have trouble achieving a good smoking temperature if it's cold and snowing?
