But it is the CMC and it is doing this in an area where the GFS progs high shear. Food for thought. Usually the CMC overdoes things. But there is a 500 mb high to the north, which is often favorable. We'll see.

Now that was what was said about Andrew! Of course we all know how that turned out! Let's see now: 92L...hmm 1992...hmmm
Sorry for the Andrew comparison, I couldn't resist...ST

If you look at the high definition Goes 16 slider you can see 2 potential LLC one south and further NE not sure which one will become dominant if any.

There is no reason to compare this to Andrew's setup as there is not forecasted to be the strength and persistence of the superstrong upper high that was then just offshore NC to its north. There is an upper high to the north of 92L but not quite like the one above Andrew. Am I wrong?

You're completely right, still cant rule out a tropical storm or low end hurricane for Florida but no Andrew is going to come from this

I edited my post to say this, but I guess you caught it before the edit.

Looks like the UK/CMC/GFS are going with the northern vort?

The CMC has two things wrong:

1. Initial low-level vorticity is too strong
2. Shows the invest building enough convection to overpower the ULL rather than the ULL inducing shear to prevent development.

It is not just with this invest but seems these two things above are the main reasons the CMC is usually overbullish. You would think the software could be fixed to better handle 1. and 2.

It is entrained in the ULL so it will be difficult for development

The northwestern Vort is throwing outflow boundaries.
Southern vort is dry again but well defined.
Any of the models that develop the southern vort recurve east of Florida?
