Re: gustav looking strange on loops

Regarding that Surface graphic image sent earlier, I see the 1012 isobar line which I am assuming shows the general shape of the boundary of high pressure area that is mentioned as "blocking" Gustav (stated like a true non-Met!)

The question I have has to do with where that "12" isobar was yesterday. It appears to be retreating east at a fair clip when you compare today's position with yesterdays position (see the attached JPG from yesterday at 21UTC).

If it continues that retreat east at the same rate, it seems like it wouldn't take long to be mostly out of the Gulf; and if so, would that not start to move the forcast direction more northerly and eventually northeasterly?
