GEFS looks better. Slight SE ridge + Alaskan RIdge further west = colder over the PNW.

Starts building in a SE ridge here. But ya, would be nice if it shoved West a bit.

All the ensembles show a big ridge setting up
Shop in the North Pacific. It’s the Largest anomaly center in the northern hemisphere and that would typically teleconnect to a down stream trough in the PNW. I’d be pretty surprised if those wonky operational runs verified(GFS). But until we see the GFS get on-board I will remain cautiously optimistic.

Just like LA tonight Nito keeps getting lots of shots on net, good thing we have Catstorm in goal.

Doesn't mean anything at this point, but it'd also be nice if the PV would actually move west into the Yukon or NWT rather than just spin endlessly over Baffin Island. But of course we'd need a -NAO for that.

Yup, that’s way out there. Hopefully next weekend stays on track.

Yes and EC never comes on board till the last minute.

[Bonovox]

The EPS supports the OP for 10 day snowfall total.

GEM ensemble mean at day 10 in agreement with GFS, ECMWF. Arctic air potential down the road in the 10-15 day range

Monty used an AF phrase cautiously optimistic sounds like a Knuckle game.

When jaya is on-board the arctic express, we will be in business.
