Good point. Here is a good example of what a solid low level cold wave can look like in the WV.

The December 2005 cold wave was a good one.  Started with legit cold and then went into a major inversion.  My area had two straight days of 60mph winds coming out of that.  What a mess!

00z GEFS says I don't(east of I-205) reach freezing Day 7-12 (run hasn't finished) PDX 31-33 and I'm always 3-4 F colder out here. This is going to be sweet!

Certainly looks like another variation of cold coming up.  Our coldest winters are often made up of real and "fake" cold taking turns.

Looks like another north central dumpage

The Swamp scored 8" going into that.

I was in the national guard at the time, and I remember seeing several inches out on Fort Lewis in the woods a week or so after the snowfall.

Root for runs the next two days to dig it south closer to the BC Coast and not so far offshore..

Top left ridge should move in to position like on GEFS in next frame.

Day 7

[snow_wizard]

Looks like some crazy blocking coming up.  Can't wait to see how it actually plays out.  There are times the NE Pacific basically has no low pressure anywhere to be seen.

[Kolk1604]

Block is better at this hour than the 12z 

[Gradient Keeper]

Day 8 That is a GOLIATH high-latitude block!

[snow_wizard]

Surface temps start to get quite cold later in the run.  No warm anoms anywhere in sight!

Slight PV disruption this year.  This winter has incredible potential.

Low level cold pool intensifying quickly. 925s -8c to -10c Gorge, Columbia Basin.

[Gradient Keeper]

Strong east wind

[RentonHill]

Some freaky sh1t. Feel like I’m looking at the Mothman or something

Does that mean everyone is stuck in a inversion? 850s are crap, but surface temps are cold

Next! I prefer something like GEFS has.

[Gradient Keeper]

Day 8.5 PDX-DLS -10 to -12mb

[Gradient Keeper]

Day 9'er wow. East wind storm. Major low level blast.

That's exactly what it means.  Fog.

That's an awful lot of gradient lines squeezed into a very small area. -24? I had to zoom way in and take off my glasses. Lol. But I think that's what I counted.

You were dang close! BLI-YWL -26mb!

[Deweydog]

[snow_wizard]

That is one serious inversion situation at the end of the ECMWF.  Temps being shown for SEA at that time are way too warm for some reason.

[Winterdog]

37 here.  Hope we will see better runs in the future.
