gfdl says 153kts?
The 0z indicated a cat 5, the 6z indicated only a cat 3. Not sure where this other GFDL cat 5 run is coming from. The 12z won't be out for a few more hours.

You can't make that reduction. The 153kt is at a surface pressure of 905mb. That wind is, essentially, below the surface so that conversion factor is tossed out the window.
Ah, I forgot about that. Makes sense. I don't know why the GFDL uses a 950 mb level then since most hurricanes are below 950.

It's a good "middle-ground" number. If you used 900mb, that would throw off weaker disturbances and would hurt the models performance during the development stage.

18z yesterday run, but it was "only" 144kts. New one (12z) is showing 151kts and 898mb.

Either nothing, a weak, moderate tropical storm (50mph) or a strong cat 3+.
That is, either this storm will shear out, become a TD or TS with max being in the 35-50mph range or, it manages to get past 65ish or so, it'll probably go all the way to a strong Cat 3 (winds 125mph+).
The way I see it follows Joe Bastardi's "rock up the hill analogy." Either it won't get the rock up the hill, and it'll fizzle, or if it doesn't fizzle, it might fizzle before consolidating and could manage into the mid TS range, or if it develops a CDO and a pre-eye, conditions will let it rapidly intensify and only stop when the first eye-wall replacement cycle begins, which could theoretically be as early as 115mph, but will likely hold off as we have seen recently until it gets near 945mb and winds are likely 130-135+.
