Need to watch the 'trends' on the means with the Pacific ridge in the LR. Really want that more poleward (-EPO) rather than a broad, flat ridge further south/west, otherwise it might be tough to get cold air bleeding southeastward without a hella west based -NAO. The GEFS has moved in that direction, although it seems to shift the ridge northward right at the end of the run. That's the primary reason for it delaying the eastward progression of cold, but the -NAO is also less impressive the last couple runs. Really need that to be stout if the Pac isn't going to be at least somewhat favorable.
