Here's a thought. If we establish a good Columbia Basin cold pool we just need a suppressed jet into California with a system approaching from the southwest for us to score, specifically PDX metro/Gorge. Something to think about.

Trying to make an accurate, high resolution map of average annual snowfall of Western Washington would be a really interesting albeit very challenging project. There are definitely places that see 2-3 times as much as others within quite short distances.

It would but I would definitely welcome the efforts. The WRF-GFS isn't getting the job done, nor the other GFS or ECMWF snow maps.

ECMWF was showing some systems undercutting that massive ridge after the backdoor blast! That cold pool building is great to see. First this cold wave and then potentially another backdoor event.

Giggity.

Mark Nelsen posted a real detailed map of the PDX metro area before that showed the microclimates.  I would almost bet that one exists for Seattle.

That was for precip, I think snowfall would be more challenging.

How's this November stack up for you compared to years past now?

No comparison. We’ve had more snow this month than all 11 previous ones combined.

These events just go to show that our climate is changing frequently and it’s really bad, it went from like highs of 80 degrees to highs of like 43 degrees like dang only in like 4 or 5 weeks and it almost snowing for Portland

Kevin Calabro is the best ever. I sure do miss him up here in Seattle.

This would be a RAD project. Wouldn’t be that hard just really time consuming going through every station’s records, and trying to fill in crucial missing data.

Day 6 (Past 4 runs) Kind of ugly

Probably not a warm pattern though.

Accurate snowfall data is so sparse and inconsistent that you’d have to lean almost entirely on personal knowledge and expertise of our microclimates.

Easiest way would probably be to start with a topographic map and make adjustments for latitude, outflow, shadowing, convergence, cold air damming, orographic lift, and proximity to the water.

Snowing quite heavily at the moment in Victoria with strong outflow winds! Grass and roofs are covered and starting to stick to pavement. 

Looks pretty good back in Saanich. I wasn't expecting to miss something like this coming back Nov 11th. I wonder if there will still be any around at the end of the week
