Hopefully the Euro & Canadian get on board more over the next day or two.
They seem to be keying on a 2 wave set up where the first wave brings some wintry weather to CTP, but then raises the heights a bit so the second wave is mostly an icy mix for most of us.
The GFS has consistently been focused the last several runs of keeping the first wave well to our south, while allowing the cold to press more. Then the second main wave approaches and rides good precip into the cold air in place allowing for a front end thump of snow. This 12z run was mostly snow from the PA turnpike on north.
