Hey All, Is it possible to smoke succesfully when it is 20 outside? I am currently trying to smoke a 2.5 pound prok shoulder. Its been on at 225 for 4.5 hours now and is only at 145 degrees. This is my second attempt at this and it seems at this rate it could take 8-9 hours for a 2.5 pound butt. How is that when I have two thermometers that verify the temp at 225-250?
