Well bad news..... I went out and checked the weber and it was at or about 250 which was just slightly less than when I checked it before. So I opened up the bottom vent some...came back outside about an hour later and it was completely burned out. The water was still fairly warm and the bottom of the butts that were in the foil pan were steaming so I think its safe. I promptly threw them all on the UDS and wrapped them in foil. I cranked the UDS up to 300 to 320 and let it roll. I got one butt done and the rest are at or about 180. How long do you think they will take to get to about 200 at 300 degrees?
I underestimated the outside temp I think. Its about 35 out right now...or less
