PNW October 2021, Pumpkin Spice Edition


The Blob

Recommended Posts

The height anomalies being depicted by the GFS during week two are pretty insane and it has been consistent.  It's showing some big time below temps also with a number of highs in the 40s.  Good stuff!

It's pretty remarkable when you look at the list of years that had the coldest first half of October since 1945.  I posted them last night and all had significant cold and snow except for 1973, and even that winter was cool with some snow.

Would really love to se the 18z run go out to h450, that open wave cresting off the coast was about to make a beeline for the WA/OR coast.

It turns out the early January 1974 cold snap was sharper than I realized.  Landsburg had 9 consecutive lows of 20 or below with highs in the 30s on that one.  And that was probably the weakest winter of the group for seasons that had a cold first half of October, unless you count 2019 which didn't quite meet the 52.0 average threshold that I used.

Another interesting thing about the GFS is it continues the theme of a west based -NAO which is often a good thing for us.  In fact that feature gets really strong on the 18z.

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!

Need a pipeline to ship all the water to directly to Joshua in Lake Oswego! 

Haha. Good idea. Or, it could just freakin’ rain here.

I have visited the Columbia River Gorge after some heavy rainfall and it’s just awesome. Same with Silver Falls State Park. I would love to see Snoqualmie Falls in its full splendor.

I guess we will find out.  All I know is like where we're at, except I wish we were looking at positive QBO this winter.  At this point the minus QBO is still only possible.   It hasn't gotten to the 50mb level yet, and the higher levels are already flipping.  2007-08 was a profoundly minus QBO.

I recall Phil mentioned a while back, but correct me if I'm wrong, that the QBO at 50mb has more of an impact on the weather patterns than the 30mb level. Is that right?

Two lows track inland well south of Seattle on this GFS run.  Incredible jet suppression for this early.  The height anomalies are insane for much of the run as well.  Kind of makes you wonder where winter may go.

Yeah a very prolonged period of troughing and a definite wind storm pattern.

Pretty amazing stuff for this early.

I'm guessing it does.  30mb is very high and the air extremely thin up there.  I think 50mb and even 70mb are more important.

This is going to be a winter for the ages, the winter of all winters, one for the record books, the one we've waited for our entire lives! C'MON!!!!

It's pretty remarkable that no rain is shown for this area until Tuesday night now.  What was originally supposed to be a wet Sunday or Sunday night just vanished.  Still a sharp cold front though temperature wise.

Yeah the best dynamics and jet support has trended south, south, south focusing on southern OR and northern CA.

Teleconnection wise this pattern coming up is really an oddball.  We will be in an extremely suppressed jet / deep trough and yet the PNA and EPO will both be either neutral of positive.  As far as I can tell the main driver is going to be that crazy west based -NAO.
