December Weather In the PNW

00z WRF ensemble mean doesn't look too shabby. Some members still look quite snowy.

 

At any rate, I can't imagine anyone would complain about getting 2 inches on Christmas morning instead of 3. :)

1” is all I’m asking for...let’s push that moisture just slightly north!!

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!

The map tim posted doesn't tell the entire story. There is more precip but as rain. However that could be wrong.

Hard to image any precip type besides snow...at least north of Seattle. It’s cold up here! Still sitting at 25. I don’t know what the 850’s are above my head though.

So you eying late January and February?

FWIW, David Gold (a Chief meteorologist @ IBM) seems to generally agree.

Haha, to the contrary. I’d been bearish on February, but I’m starting to think there might be a chance for some amplification if the MJO stays active and prevents the NPAC from locking into a -PNA/+EPO regime.

Ok maybe I didn’t understand it well enough. :lol:

Haha, yeah I think I should have clarified that the teleconnective mechanics through which the tropical/extratropical relationship operates are structurally different in their spatial exchanges later in the winter vs earlier in the winter.

Hmmm, that seems a bit hard to believe. They might be confused.

 

So it raining in Hillsboro and Tigard?

 

I see wet roads in some places... not seeing snow on the traffic cams yet.

How long this lasts is important, too.

 

There will undoubtedly be a period of PV/+AO strengthening next month. So, we’ll need to find a way to dislodge it.

There's a few pellets of sleep falling now. Current temp is 29 with a dew point of 23. I feel like it's gonna get nasty in the PDX metro today.

Sleep pellets? Ambien’s falling from the sky!!

Did you move?

Yes, and Dewey moved to the Coast, Phil moved to Florida, Tim moved to Bellingham, Umadbro moved to Sunriver and Flatiron moved to Salem.

 

Everyone knows that no one here visits a place for the holidays without moving there permanently. ;)

We come from the land of the ice and snow.

My brother just told me it was snowing in Gresham. I also noticed a couple flakes mixing in with the sleet here. I'd say this is a great sign for those up north to stay all snow today.
