Brisket - negative stall

[michaelt1959]

Hi all.  5 hours into a 20lb brisket.  Stall at 155. I'm patient. It's been an hour now ....but she is moving backwards. I am now at 151 and dropping slowly.  My temp is VERY consistent @ 225.   This is probably my 50th brisket in 18 months and never experienced a negative move.  Is this to be expected? Anything special I should look for?

Thanks in advance for your thoughts, as always.

20lbs is a BIG brisket.  You could wrap it in foil and that will help it through the stall, otherwise keep putting heat to it and the temp should start climbing again.
