I'm excited to see if the record highs and record flooding equate to a big winter like they often do when they happen in a La Nina November.

Saturday's system is definitely a noticeable notch further South on the 12z through hour 66. Cooler air is a bit further South over Western WA ahead of it as well. Seems like this run will show snow again Saturday morning and probably more than the 00z and 6z.

The 12z is about 25mb stronger with the Monday morning low. Crazy difference despite being in basically the same location.

GFS back to showing lowland snow Saturday morning.

It seems like the faster timing helps... as it comes through mostly during the night on Friday into early Saturday morning on this run.     Precip is basically done by dawn on Saturday.

That's a hell of a thump of heavy wet snow Sunday night on the 12z for Western Washington. Shows about 6" for Seattle.

12Z GFS shows about a foot of snow in Seattle over just the next 5 days... going to be a really good test for the GFS snowfall maps and we will know the results very soon.

Yes, that pattern can really slam me out here. If something like the 12z plays out we'll get buried with wet snow and loose power for days.

For comparison and scoring later... here was the 00Z ECMWF through the same time frame.

We need to take your dad's Oldsmobile and drive over to Tim's house with a case of beer and see if we can go out and pull some wheelies in his neighborhood. 

Sounds like a perfect day! Though I can’t imagine it would do very well in the snow. 😀
