No idea why the white crop is so large on these png's... Anyways. 06z GFS For around the 27th is typical for phase 7 at that time of year, as we are forecast to be in by the given time.
Rolled forward into mid December assuming we stall.... No wonder there's been a lot of eye candy. That's a cold pattern. Whatever arctic air does pool in Canada over the next three weeks may very well dump itself into the PNW come the holidays.
A progression into phase 8 would also support a colder pattern with more undercutting. December would be a great time to stall in regions 7/8.
Great minds think alike. Yeah, we can work with this just need a few adjustments to 500mb pattern. I do like the negative anomaly remains shunted well west near 170 W to dateline.
12z GFS in 3 hours 32 minutes
Night Shift 6z GEFS - Day 7-12. This run tried to get there.... Some improvement. The 500 contours did bend around some in response to slightly more favorable blocking upstream. 850s shows arctic air just over the border into British Columbia/Alberta. Don't lose hope just yet.
