Op een Engels forum vond ik wel een aardig inzicht, wat mijzelf nog niet was opgevallen.
One thing both models( GFS and ECM) agree on is the main part of the vortex transferring
over to the Hudson bay area with a -A0 developing in the high Arctic.
This would gel with the idea of heights increasing to out north and northeast. The main difference with this run is that it has moved the main part of the vortex over to the north of Hudson Bay and Baffin Island, allowing better heights to the north of us.
