Its the strength of the two systems that's creating the havoc, GFS is weaker and further south, Euro is stronger and further north, Right now, I would lean GFS, It seems to have more support on a weaker system.
If we had a colder air mass over us that would be a classic right to the coast, Its going to be slop more then likely here but back by you and NW of there looks to be a paste job verbatim.
I just looked at 12z, There was more spread but the left members were inland over Maine as well so they shifted a bit east at 18z tracking into the Bay of Fundy with more members.
Euro is pretty dynamic at the surface dropping 12mb in 12 hrs to 986mb in the GOM, GFS has had a weaker further S solution up until 18z, So we will see if that continues to change going forward.
Looks like there both finding some middle ground, A few tics south on the euro, A few tics north on the GFS, Kind of what i had thought when the Euro was over amped and the GFS was flat, 50/50 split yields a decent track but air mass needs work.
