I put a brisket flat on this morning at 6:30 along with some spareribs. Ribs on top brisket on bottom. I just took the ribs off, they were at 190 average between the ribs. I moved the brisket up to the top grate and put my polder probe in and it's already registering 187!! I just checked the thermo last night and it was spot on perfect. My WSM has been running steady between 230 and 260 (at the dome). There was a short period where it spiked up to 280 but I was able to get it back down within about 15 minutes. I find it hard to believe that it's at that temp already. I moved the probe to a couple of different places and it's 187. I'm going to leave the brisket on until it hits at least 195. Any ideas?
