We experienced this with Debby. King Euro (my fav. model) along with many others gave too much weight to the ridge. By 96 hours, the ridge, unlike with Debby, will be WAY out over the mountain west with a fairly deep trough digging into the eastern conus. The ridge amplifies even more going into 144 hours basically in the same position. I see a pretty big weakness in the atmosphere and would definitely give more weight to the models showing a northward bias than the ones that send it to Mexico. AT THIS POINT (which is always subject to change) I see no reason why the trough won't continue to dig being that there are several shortwave impulses imbedded in the trough. My point here is that it is way too early to rule any one spot out.

I am certainly not a met, but if Ernesto is still weak or at least a lot weaker than is thought in the W Caribbean, I would think we would be dealing with a more Westerly course, with much less chance of a N or NW turn. Are you taking this into your thoughts in this discussion or are you assuming Ernesto will be a cane at that point?
I suspect we'll have a 'cane. I'm basically right on target with the NHC. Of course a weaker storm (being shallower) would continue on a more westerly track but I agree with the NHC. I think conditions are favorable for deepening. It's been a while since that area of the Caribbean has been really churned up by something big.
