Thanks for the suggestions guys!
Luckily I don't think it is supposed to be too windy tonight and the deck that my smoker is on faces south and is up against the wall. It is just going to be darn cold and even colder tomorrow night.
If we are talking about the same smoker, I know of the cover that you are talking about Dave. I have one of those smokers, but made my own cover out of the same Reflectix material that their cover was made out of and was able to buy an entire roll of Reflectix for the price of what they wanted just for their cover.
My first smoke was done with temps in the 0-10F range and I had no troubles at all getting to temp. So, I am going to gamble and just run it like I did before and hope for similar results. I was amazed at how long it took after the element turned off to sink back down to the point where the element kicked on again. So, kudos to the insulation on the SI units.
If I have any problems, I think I will buy another roll of Reflectix and make a cover for the next cold weather smoke.
I have guys coming over for poker night to tomorrow and we usually play for quite a while. So if it isn't done by supper time, I won't be too worried.
The one thing I think I am going to change though is to start smoking at 8:00 instead of 10:00 as I originally had planned.
