My new favorite sat is the western Atlantic water vapor loop, which will soon be even better as Ivan enters the picture.

The ridge over the US seems a lot smaller than it did yesterday, and the one over the Atlantic has weakened. The effect has been that the trough over Florida continues to be stationary. Unless movement occurs again, I see this as the path Ivan will take... that of least resistance.

So, for the first time.... the models and I are on the same page.!
