Seems the models are more in love with the idea that she’ll take a licking but keep on ticking.

The GFS/GEFS is less bullish, but the EPS (performs much better in strat) is going all in.

There’s a boatload of cold on Putin’s side of the pole. Evident via the jet extension triggered by the Siberian high descent.

Our side is lackluster thus far, but that’ll change eventually.

Been another very mild month in western Russia. Been colder to the east, but much of Eurasia has been mild. Seems like Siberia and East Asia are the sole focus of any cold air so far.

Right now... the Twin Cities is going through the same rapid warm to cold transition that came through here on Monday.

The western suburbs are getting buried while its raining in the eastern suburbs... and it will be below zero there by tomorrow morning.

Next 5 days. That’s actually a decent amount of cold.

Minimum anomaly is -17.2, maximum is +12, so the cold anomalies are more extreme than the warm anomalies.

I think we are losing Matt...And Jim is awol again...Not good. 

I’ve gone through a meteoric weenie shift to the belief the last 1/3 of January and into the first month of winter have potential.  Frequent naps and journaling are recommended until then.

My preferences can beat up your preferences’ dad.

Big question is whether the SSW event remains wave-1 dominant (displacement & decay of PV) or transitions to feature more wave-2 (quick split).

Both 2018 and 2019 had significant wave-2 components. Late Jan 1989 was the 2nd strongest SSW ever recorded in terms of amplitude, even though it was mostly wave-1. But it was so massive it didn’t really matter..wind reversal still took place and cold just poured out of the arctic. Also aided by the deposition of easterly momentum.

So when the polar vortex splits, its called a wave-2 event? And this is the best outcome for a PNW arctic outbreak right?

Yeah I have a feeling February and March are going to continue to separate themselves from all other months in terms of snowfall up here.

It would be cool to experience a winter in Burns, OR. One living at the end of the earth would be an interesting experience. Plus they get real winters out there. 9 for a low this morning. 

https://en.wikipedia.org/wiki/Burns,_Oregon

We went through there for the first time last summer, to and from Steens Mountain. Even spent a night in town on the way home. Walked the neighborhoods on a cool mid-July night (temps in the 50s) and the views of the milky way were stunning. Some nice older homes too, tree lined streets.

I've been told by older relatives you used to be able to see the milky way on clear nights in Portland, pre-1960ish.

Gusty east winds here. Cold winds. I guess I'll enjoy this the next few days.

Yeah at the very least there looks to be a lot of that the next week.

It still tries to show some overrunning at the end of the month. Pretty splitty with everything though. 

If Tim was inspired to post a frame from a run for the first time in a month you know it's a massive step back.

Would be nice to score a high in the 30s. I've managed a whopping 3 so far in 2020 (2 in January, 1 in November). PDX, VUO, and SPB still await their first.

Don't think we're gonna do it here locally, there is a lot of sunshine.

I think I scored a high of 39 at some point back in January but I'd have to double check.

All potential for a Eastern Pacific block is lost when Greenland goes into a rex block.

I am rusty with this stuff but I thought a Greenland block wasn't necessarily a bad thing for us. Or at least represents some kind of shake up. Seems our rather warm background state of the last several years has often featured a stubborn Greenland vortex.

23 years ago today we had a nice little surprise snowstorm.  

I’m getting tired of doing math all of the time. 

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!
