Best I can tell the ukmet favors the EURO more than the GFS at 144hrs. ICON looks like it's setup for a monster storm at 180hrs as well. JMA doesn't leave a cutoff low behind in the Southwest. It appears the GFS is on the far end of guidance with that feature at the moment. Hopefully it's wrong.
for the record, the CMC leans more towards the GFS in regards to the energy retrograding in to a closed low over the southwest before kicking east.
