I didn't read the 5pm NHC disc until now, but they mention the turn north, and the gfs being much much faster than the Euro (or GGEM for that matter)
Satellite and aircraft fixes show that Lee is moving west-
northwestward at about 9 kt. There has been no change to the track
forecast philosophy. A mid-level ridge to the north of Lee is
foreast to shift west-southwestward during the next few days,
causing Lee's forward speed to slow considerably through early next
week. By midweek, a mid-latitude trough moving across the Great
Lakes region and into the eastern United States is expected to
weaken the ridge and allow Lee to turn north-northwestward and
northward on days 4 and 5. There is still a significant amount of
spread in the deterministic guidance and global model ensembles as
to exactly when and where the northward turn takes place. In fact,
the GFS and ECMWF models are about 275 n mi apart at day 5,
primarily due to along-track spread related to how fast Lee begins
moving northward. The NHC track forecast continues to lie near the
latest consensus aids, and the new track is very similar to the
previous forecast.
