GFS is basically not worth looking at past day 5,day 4 and in it does get better and carry some weight.
The difference is around hour 72-96,the GFS pulls the 594dm death ridge out sooner along the VA,MD coast giving it room to stay east.The Euro holds the 594dm death ridge in longer and lets it steer more west.I would look for a middle of the road compromise here in my opinion,a stall out is possible too because of no steering currents once it gets to the coast either.
Carry on.
