This is the second model "wavelength" I was talking about now showing up. GFDL leads with its tail so it is definitely taking the trough into consideration. This is now a tough nut because GFDL has already overblown a trough recurve west of Florida with Ike. The second wavelength is now a poleward rightward influence instead of an under-ridge influence that GFDL excelled at. I have a feeling they'll err on the safe side and you'll be hearing of an evacuation of Houston shortly.
I dont think they will base the decison on one run of GFDL, I thin they will make a call after 4PM advisory. If euro swings east, I think track moves north, if it moves south near current landfall track by NHC, they leave track as is and discount GFDL until more move over to confirm.
