Also interesting to note that the low in eastern US is also further west and pushing more hot air to Greenland area than in the previous run

The result: GH 10mb stronger
So far none has mentioned the biggest difference in the medium range between GFS and ECM .
In the gfs the atlantic low is very well blocked and the energy is moved around the GH
Therefore, there is no low moving towards Iberia at t144
On the other hand, the ECM shows that low moving towars Iberia
We will see, for example as this low is deeper and the track is different than in the previous run, you can see that hot air is transported to Greenland, and the GH is stronger and further west
Here you can see it

BTW, intersting chart at t384h
PV moved from Canada to our east
Highs moved from Escandinavia to Greenland, so a GH very likely to happen in this chart
The result of this two changes could be awesome
Lets say that he takes you something from you and he shows you something possible in the future, and you have to wait again to become it real, if it does.
