Temp 37.4, dewpoint 18.7 with gusty east wind. If you ask me by mid-November standards this is pretty much a modified low level blast.

For sure.  That Canadian High brought in some decent low level cold for this time of year.  The lower Fraser Valley is getting freezing winds in some places right now.

-6 at Foster Flat in SE Oregon.

25 already at Corvallis. This reminds me so much of November 2000.

It is similar in a number of ways.  We just missed getting major cold in December that winter.  It got chilly here, but we were on the edge of it.  The mean block position has been further west this month than in 2000 however.

Currently 28F under beautiful late fall/winter stars. Crunchy ground. Honestly this has been a really nice stretch. Every night so pleasantly cold.

Anybody catch any Leonids??

I think I’ve decoupled. Do I call 911?

Day 6 another cold pool and east winds?

[Gradient Keeper]

Strong east wind!

Some similarities to 2014 so far. Record warm ASO, cold early/mid November. And the big Buffalo lake effect snowstorm started today in 2014 as well.
I don't think this winter will be like 2014/15 though, I feel like we'll have a better chance this year

That winter had two incredible cold shots out this way. Never before had we dropped below zero in mid-February on cold advection alone/no decoupling. Not to mention bare ground at the time, as well.

There was so much cold air around that despite being in the warm sector with southerly winds it was snowing and 18°F at midday. That simply isn’t supposed to happen here. Would have been rare even in the 19th century.

I'm hoping it's more like 2013/2014 where the majority of the country got the cold

Only if it lasts more than 6 hours.

[LowerGarfield]

I’d be thrilled with another 2013/14 as well. Probably my second favorite winter of all time, behind 2009/10.

Actually had a low key snowpack that winter. Ground was never completely bare from new years to the end of march. And it snowed in December, which seems almost impossible these days.

Day 8 What's this?

[Gradient Keeper]

00z GEFS. This isn't bad. At least it's not dry and mild.

[Gradient Keeper]

Day 9'er Now that's an improvement. At least it isn't dry and mild.

Day 10

[Deweydog]

COLD ONSHORE FLOW

[Gradient Keeper]

I like this.

[Gradient Keeper]

00z ECMWF 10 Day Rainfall totals, including the southwestern US.

[Gradient Keeper]

00z ECMWF 10 Day Snowfall totals, including the southwestern US.

[Cascadia_Wx]

ECMWF looking much better.

[Gradient Keeper]

Wow. I am now having gusts very close to rivaling the wind storm Wednesday night, early Thursday morning.

[SilverFallsAndrew]

Down to 5 at Burns.

Pressure Gradients - UPDATE

Offshore gradients have ticked back upward this evening as high pressure strengthens a bit over the Columbia Basin. In response the east winds have ramped up again and at my location near west Gresham I am now experiencing bursts of loud, roaring gusts that are close to rivaling the east wind storm Wednesday night through Thursday morning. It's going to be a very windy night, but gradients should weaken slowly yet steadily tomorrow. One last night of strong wind gusts mainly east of I-205.

11 PM

[Gorge/Gap Gradients]
PDX-DLS: -8.7mb
TTD-DLS: -8.2mb

[Cross Cascade Gradients]
PDX-YKM: -9.0mb
PDX-MWH: -9.0mb
PDX-GEG: -8.4mb
OTH-GEG: -13.7mb

*Legend: PDX = Portland, DLS = The Dalles, TTD = Troutdale, YKM = Yakima, MWH = Moses Lake, GEG = Spokane, OTH = North Bend

A -Negative value denotes easterly/northerly flow
A +Positive value denotes westerly/onshore flow

What's a Pressure Gradient?
A pressure gradient measures the difference in Barometric Pressure between two locations. For example, PDX pressure is currently 30.38 in and The Dalles is at 30.62 in. Higher pressure at The Dalles and lower pressure at Portland induces an east wind through the Gorge.
