For years now, we've seen a tendency for the TPV to not fully slide eastward under Greenland blocking when we've had opportunities for it to. If that TPV doesn't fully come under the block and into favorable position in northern New England / southeastern Canada, which the EPS out to 2/19 still isn't showing a definitive signal of, it will likely wreck the pattern and either the Midwest and/or New England will be getting snow while we continue just like we have been. It is hard to break these kind of year-over-year tendencies.

At least as of now, it seems like the weaker the TPV is, the more likely it will be to slide east. If it remains very strong, it appears more EPS members keep it further west. Something to consider.

Until we can move beyond this multi-year tendency, I think it is wise to continue to look for and assess the signs and indications that it may happen again, while obviously hoping and praying it doesn't.
