Not saying that the GFS or GEFS is right, But the euro hasn't been steadfast either, The only flag that i still see is that the 06z EPS took a good bump north too, But we shall see here at 12z.
Exactly what you don't do, You look at all 31, You look at the mean, That will tell by where that's tracking and possibly heading and there are several that are tracking further NW.
Another tick or two on the Euro and you will have the track, Thinking 60/40 Euro/GFS blend right now, Starting to see where the convergence on track will be, Will start earlier then modeled too, Typical SWFE favored climo.
