Just comparing a few charts, but the NAE has the front at 48 hours slightly further North and West than the GFS or NAVGEM does, maybe the NAE wants to bring it into the SW? The NAVGEM has been showing the front coming right over us now for a while but problem being it would turn to rain as the milder air mixes in, hope the NAE is on to something and the GFS is beginning to adjust to it now.
