I will be honest, I'm not sure I understand why the look going past President's Day is not a better than average look for snowfall.
The blocking remains, therefore pure cutters should be limited.
Is the problem that the block is too far north?
If anything it seems we are following the same pattern as the last passage through eight one and two, where we had a large snow storm at the start of The blocking period which favored the Mid-Atlantic, which the GFS is currently showing, followed by a wave providing a light to moderate snowfall with a GFS is showing, followed by a trough in the east which the ensembles are showing.
Therefore I would believe past President's Day, obviously not forever but for a week or two, should be at the very least colder than average with the main risk being suppression just like the last passage through eight one and two.
