NAM3k does it right. Frontal precip merges with warm advection precip and keeps steady snow going all afternoon through Friday morning.

Yeah. The atmospheric PV is not translating down to the troposphere as evidenced by the low AO. Just another mystery this season.

Weekly is good. We have been baited quite a few times however. But this progression to getting cold makes more sense than complex one previously shown. Also Feb

That was the ensemble and it's only the second best. From what I understand the ECMWF based graphcast is the best. I found out the other day there is a GFS based graphcast out there too.

The NAO and WPO have both been negative overall this cold season. Also the AO at times. Just goes to show that if the EPO/PNA aren't negative, doesn't help much for the PNW.
