Good news. Looks like PDX got to 27 last night. No longer breaking the record for warmest annual minimum in the airport era.

Unfortunately clouds and fog at HIO prevented what could have been some epic radiational cooling.

Outstanding.

Beautiful morning in the Blue Mountains of eastern Oregon. It was 12F when I took these pics around 8:30am.

Gotta get our winter fix somehow.

Gold was first struck here on July 4, 1862, after which the area underwent a mining boom/the town was formed. So most early residents just missed it.

Although it’s likely there were a few grizzled prospectors up here the preceding winter.  I’m sure it was brutal. 🥶

Stayed at the freemont powerhouse just up from there toward olive lake.  That was a year and a half ago.  Good trout and Kokanee fishing and a few mushrooms too.

Nice. We are planning to snowshoe in the Fremont Powerhouse area today.

You can rent those houses for like 80$ a night. Although I think there is no water in the winter time. There is a wood pipe that goes from there to olive Lake (7miles) it’s probably mostly buried in snow right now. But pretty cool They used it to create power at the powerhouse and then it ran all the way down to Sumpter.

Don’t want to jinx it, but man, I’m growing increasingly bullish on the possibility of some legit winter weather for 2nd half of January once MJO propagates out of the IO. That’s the final piece of the puzzle after SSW.

Thinking about Ventrice's tweets about SSW events in Siberia, and usually 2 weeks after maturity the cold air is in Western North America.  Thinking it explains in part Feb. 2019 even though it was a nino.

So I wonder how often in the past there has been a Nina, Westerly QBO, and a SSW event over Siberia, and how often the PNW got cold after that, vs. how often it did not get cold after that.

Also looks more likely this is the first legit -NAO DJF in almost a decade.

Depending how this ultimately plays out, we could also be looking at a more sustained shift to -PMM/-PDO and canonical -PNA (as a low pass feature below seasonal scale).

Recall the flip to +PMM/+PDO in the 2012-14 period was concurrent with flip to +NAO era.

There may be like 3 people here that understand any of that.

So are you saying we may be entering a period where the PNW may once again be more prone to arctic outbreaks in the winter?

Brutal. Sucks to have such a long stretch of monotony when it comes to bush league max temps in the winter.
