I know this is long range nam when I am showing hour 84. But you can’t help too noticed that the dew points are 10-15 difference between the nam and gfs. This just backs up what I was saying just a few degrees can make a big difference.

GFS dew points 84 hours

Also, EPS holds it longer and is stronger. Just based on past history these do tend to want to lift out as we get inside 72 hours. Though, I like the GFS run, we get some front end snow with the overrunning while the cold is established.
