Higher heights over the chimney and a trough digging further south with that northern stream vort will allow more ridging out ahead is what we need to see going forward.
Heights are higher over the the west, Northern stream digging further south, Trough goes negative a bit sooner to and nice tug back NW a bit late but looks good CNE/NNE, Closed contour over NY at H5.
On that date, We had over 1' of snow here with Blizzard conditions.

The CMC has it as well so its getting support but the details are far from being determined, But if this storm is as slow as modeled right now, Someone is going to get walloped.
