Lots of time for details to come together late in the week. I’m betting models slide cold air much further south than currently shown as we uproche erle negzt weake

I agree, and there doesn’t seem to be any end in sight for the cool to cold air!

Elevation 580’ Location a few miles east of I-5 on the Snohomish Co side of the Snohomish/Skagit border. I love snow/cold AND sun/warmth!

Totally amazing!  The GFS and ensemble have made a decidedly colder turn for late next week.  The trough digs closer to the coast than previous runs.

Tuesday morning is a go on the WRF.  Shows an inch or so for many areas.

The ICON shows some Fraser outflow commencing later in the week now also.  The surface high complex has a much more favorable look to it vs previous runs.  This cold episode doesn't want to die.

You’re right. It looks like both the GEFS and GEPS bring the low closer to the coast. That has to be good news, right?

 

It is.  More chances for the right combo to finally come up for Seattle.

It's going to be fun to run the numbers on this cold snap vs prior ones in this time frame.  The one week and two week average temps could be pretty eye popping.  Many places were right around -10 for this week.

You are not allowed to show maps on a weather forum...everyone is supposed to look at the models themselves and not share or discuss. Direct orders from Arctic Front.

Looks like SEA ended up at -10.5 for the week.  That is big league cold for this time of year.

It's there, but the details on how it will play out, how long it may last, etc aren't that clear.

WRF shows a pretty solid one bouncing between Northern King and Southern Snohomish County most of the day.

 

Borderline temperatures, though. It will take some fairly heavy precip to get sticking snow below 500 feet during the day tomorrow, because temperatures will be in the low 40's outside of any CZ action.

Everett Snowfall (510 feet elevation)

Snow since February 2019: 91"

2023-24: 6"

2022-23: 17.5"

2021-22: 17.75"

2020-21: 14.5”

2019-20: 10.5"

2018-19: 24.75"

Not much of a cz

 

Its there... it shows up better on the precip map.

I think the reason it does not show up as well on the snow map is the temperatures tomorrow afternoon...
