The best part of a good snowstorm around here IS the disturbance of every day life. It brings out the kids in adults and most people enjoy it. It really is magic around here when it happens and you do

I've been lurking here for years and rarely post, but let me just say this about the ridiculous Tim criticism. 1) You've all added about 100x more attention and energy to these "negative" posts than t

Just for you, snow wizard!!  1969 near SeaTac Airport.   Found these while moving my uncle out of his house.  My grandfather sent them to him when he was over seas fighting in the Vietnam War.   Grand

6z GFS Ensembles. 500mb pattern largely unchanged and very similar to the Op.

 

Portland - No changes. Enough -5c to -10c members to keep things interesting.

Seattle - Some improvements.

This 6z GFS run makes it 10 out of the past 12 Op runs that develop an ideal or nearly ideal 500mb pattern delivering arctic air. Focusing on the short-mid range "believable" time frame. Timing has moved ahead a bit. The pattern develops at Day 4-5 and Block pivots at Day 6. Long range Day 10.5 Aflac duck block appears again. Looking promising. Cautiously optimistic.

 

12z GFS in 3 hours 19 minutes

12z GEM in 3 hours 39 minutes

12z ECMWF in 5 hours 34 minutes

 

Think Cold and SNOW!!!! ❄ ❄ ☃ ❄ ⛄ ❄

Power is out here. Woke up to my 5yr old screaming upstairs in her room...Note to self, get another plug in flashlight that automatically comes on when the power goes out like we have in our room.

 

Guess I will head out and get the generator going if it doesn’t come back on soon.

Still very gusty out.

 

January 2020...The month where weather finally happens again!

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!

Great looking 06z. I’m liking the fact that it trended a little cooler with the troughs in the short to mid range as well.

 

Super excited to see the mountains get CRUSHED with snow starting tonight into tomorrow.

North County you have the best of both world's Environment Canada's forecast for Abbotsford or the NWS for Whatcom which do you pick a blend of the two and hope for the best? ever kept score on who nails it most for Sumas.

Environment Canada is best for winter weather alerts. NWS tends to be Bellingham-centric for lowland Whatcom County forecasts, and the conditions can be worlds apart between here and there, particularly in the winter. My house sits 50 yards south of 49°, so for all intents and purposes I live in Abbotsford, which is big enough to merit it's own independent forecast from EC.

The only downside I'm seeing with the most recent GFS runs is the tendency to make the block less amplified and connected to the Arctic, at least initially. This isn't a huge deal, but it's a big part of the reason the insane cold hasn't moved into semi-believable range.

 

Compare today's 6z for next weekend with the 0z from two nights ago.

But aside from that, timing is slowly moving up and things are looking good.

Power is back on, the generator got a good hour of exercise...All is a go for when we get 7 feet of snow and the power is out for weeks.
