The AK vortex is going to flood Canada with Pac air. The advertised +PNA look towards the end of the GEFS would be completely impotent for our purposes if that look materializes.
The 6z run this morning hinted at that trough retrograding towards the Aleutians. Not happening on the 12z run, and not on the EPS either.
eta- As I said this morning, an optimist could evaluate the h5 look at the end of the GEFS run, and see the 'possibility' of the pattern becoming more favorable just beyond that period. Problem is, we have all been doing that for months, and it never happens. Maybe this time..
