Pacific Northwest Weather

I have to disagree. The ridge starts out at 150W which is perfect. The surface pressure maps show strong Fraser River outflow. It doesn't get much better than that.

Hey everyone... Don't always take the models by face value... Ex... The cold air is going too far east and into the rocky mountains...

O.K... guys. This is going to keep you busy for a long time!!!

I linked to something on another thread and stumbled upon this FASCINATING site.

I found a link to all of the Monthly Weather Review journals from the late 1800's to 1973. After 1973 you have to pay for them.

Anyways... here is one link (as an example) to the overall review of January 1950. Its a huge file so I hope you have high speed internet access...

http://docs.lib.noaa.gov/rescue/mwr/078/mwr-078-01-0013.pdf

This next link is the index to all of the volumes. I have figured out that 1950 was volume 78 and 1973 was volume 101. Determine what year you want and then convert that to the volume. Click on that volume number and then you have a list of all articles for that year. Kind of complicated... but I have found there is a overview for each month from at least 1950-1973 and probably way before.

Let me know if you guys can access this stuff.

Its best to use the index (second link) and then save the PDF files directly to your computer when you find volumes and articles you want.

It's times like these I wish I had cable (or even DSL would do).

Just reading the January 1950 overview... the authors were amazed at the strength of the high pressure that month over the Bering Sea. Rivaling any they had seen in the Northern Hemisphere.

That is why there was such a cold trough over the Northwest all month.

This is like going back in time!!

Cool stuff TT! Oh how cool it would be to witness a 1950 event!!! 8-)

Well I am not planning on moving out of state, and being 28yrs old hopefully I will have at least 40-50 more winters to witness something :lol:

Has anyone else noticed that both W-13 Justin, and Cloud9 haven't been around for the last few days? They are typically here all the time, well at least Justin.

00z GFS looking cool to cold for us by day 8!!!! I think the pattern is starting to change to a colder one, maybe snowier! -9MB 850 Temps by day 9. Things are starting to look up 8-)

Although the 00z GFS looks promising, I won't believe anything till I see some consistency...maybe five or six runs showing the SAME thing. But until then, I'm skeptical. At least there's some diversity...not one, big ridge sitting over Western Washington. lol. Goodnite to all!!

Here is the January 1969 overview with comments on Seattle and Stampede Pass...

You can clearly see in 1950 and in 1969 the pattern that resulted in such a wild January in both years.

I have been trying to find evidence of what the pattern looked like back then and what to look for in the future.

Awsome find TT!

The 0z run continues the trend of showing offshore ridging and northerly flow developing next week. Maybe we will have a cold Feb after all!

Good evening folks.

looking at tonights GFS for next Monday - Thursday ....looks like well have a few showers for Monday..with a good cold front coming through here Late Monday that could drop about .50" of precip for the 24hr period ending 12z early Tuesday morning. After the cold front comes through, a weak High pressure system will build over us and keep us dry through about the late Thursday time frame. 500MB voricity heights are around 564DM...and going up near or at 576DM by end of work week. 850MB temps showing near +6C degrees, with heights of 1560 to near 1590M. As I said before, this is spelling WARM temps for mid-late next week with possible high temps near or at 70 degrees in a few locals. In the somewhat longer run....5th - 7th..850MB temps cool down around -6 to
-9C despite having VERY high heights. Unfourntunly during this longer time frame, there is very little to no precip. So best bet is just maybe a pinch of snow for the cascades. The Cascades REALLY need snow!

In the longer run through 384hrs...looks as if we have some cooler weather come our way, by say... around the 13th of next month.

TT...I take back eveything I've said about you. LOL... :lol:

Those monthy summaries you found are incredible! It actually shows the very storm that brought 40 inches of snow to Palmer on Jan 26 - 27 1950. 40 inches in one dump!!! With the highest temperature during the entire event 21 degrees. PLEASE let it happen again....PLEASE. It is intersting to note that there was a strong east wind pressure gradient on that storm. How remarkable that the downsloping did not hurt that storm one little bit. I am still trying to figure out why the east wind is so helpful sometimes and not others. That is one of the great weather mysteries of the foothills! I know part of the answer, but not all of it.
