grill temp vs dome temp

I'm in the middle of doing my first brisket today for Easter.  Got the parents and inlaws coming to eat.  Using a new themometer that has a grill clip for it to monitor the temp down at the meat.  Im noticing quite a difference in dome temp and grill temp....right now showing dome at 250 and the grill temp is only 206.  I know there will be a difference in temps but I was not expecting it to be that dramatic.  Anyone else experience something like this?

    The longer the cook the more heat soaked the ceramics become making the heat much more even between grate and dome 

    what youre experiencing is normal

    A man with one watch always knows what time it is. A man with two is never sure. =)

    Personally, I never check grid temp. BGE puts their thermo in the dome, so does my oven manufacturer. Also, most recipes specify dome temp. Good enough for me! 

    I hate it when I go to the kitchen for food and all I find are ingredients!

    Quite normal.  Not that dramatic.  The exact placement for the grill probe makes a significant difference.  How close is the probe to the cold meat? Is the probe over an open area with direct exposure to burning lump or protected by the indirect ceramics? Is the probe over a liquid filled drip pan?  All make a difference.  It can be hard to get consistent info from one cook to another because of all these variables.  Clip the probe to the BGE dome probe.  Or replace the BGE gauge with your new one, if it fits.

    In cooking, often we implement steps for which we have no explanations other than ‘that’s what everybody else does’ or ‘that’s what I have been told.’  Dare to think for yourself.

    Choose if you want to monitor grate or dome and stay with it. Monitoring two will drive you crazy. I monitor grate temperature. I make sure the probe is about an inch from the meat and protected by the plate setter. Don’t drive yourself crazy monitoring two temperatures. Learn one and stick with it.
