Only 4.5 hours in and already at 157? I hope this don't do what my last one did and get done way to early!
That doesn't sound odd to me at all. Don't panic. It's probably going to sit in the stall zone for many hours, and the last 10 degrees will take forever. You should be able to double wrap in foil and a towel, and rest for up to 5-6 hours in a cooler, and after that, keep warm at 140 if you have to, but I bet you won't have to. I go a minimum of 195 in the flat, and 200-205 in the point. Some people even go higher. When people go lower, I often hear that the meat was "dry", but I think it was just not "tender". What are you planning?
