If this movement holds for a little while throw in these three options:
1)He won't come out at all
2)He'll get pulled back into the central GOM, stall,and then we have to wait for the next trough to try to get him
3)It still comes out as the NHC predicts, but you better start shifting landfall more to the east

But I think this will really have to hold for some hours for a wrench to be thrown in the forecast. Of course, I am very unsure it will come out to begin with. This better be a heck of a cold front that's coming down thru the Northwest, otherwise they could be really off the mark. But I don't think they made such a drastic change in the forecast on a whim.
