The recipe for snow this year is a +PNA and -1-2 sigma NAO. Until both of those line up it’s gonna be hard. PNA may go positive around Jan 20th, let’s just hope -NAO can hold on.
Looks like 12z GFS is more suppressed then 6z. In fact, last two or three runs have a gradual suppression.
That’s goood for us. More suppression gets us in the higher totals. Will push the rain snow line south.
GFS continues to show long range storm threat of some sort September 24th. This is the 3rd or 4th run in a row. Unlikely to be correct but worth mentioning.
18z GFS is SW of 12z at 150
GFS continues to adjust to a further southwest solution with a slower recurve.
Last several runs clearly show the progression
