    GFS model bias is to break ridge down too much, Very warm SST plus model bias has always been mainstay of ideas here since a week ago today.

What I always thought too, but no deny the Bermuda ridge has been trending weaker the past few runs on the GFS and I think it's because of the upper low in the east atlantic has been getting stronger. The SE Canada ridge has been trending stronger on the GFS so it's not climbing north. We better hope the GFS is correct about the Bermuda ridge breaking down.
 
CMC never really strengthens Florence, lowest pressure I see is 979.

I think it’s too expansive with Florence at 500mb which gives it a northern bias. It was too far north with Jebi for the same reason.

GFS gets flo all the way down to 908mb as it rotates just east of the OBX for days on end. I know waters near the OBX are extremely warm right now but damn

GFS is not ocean coupled and what it shows would not happen. Dry air from land and upwelling wouldn’t allow it to keep strengthening like the GFS shows. I think the GFS is also a bit too far east. Euro tonight is important. As a summary here’s what models have shown tonight so far.
GFS - Slightly east and stalls.
CMC - Basically the same landfall location
ICON - Slightly east
NAM - West and faster
UK - Huge east shift, can it really be trusted at this point? Stalls it offshore by hour 120.

Euro, FV3 and NAVGEM are the 3 other main runs left.
 
HWRF is slightly east of the 18z, maybe a little east of Wilmington

Edit, into Wilmington again, a little weaker than previous run
