Mean temp of 34.5°F last month at YVR. Last year’s mean was 33.6°F.

SEA ended up at 38.8 vs 38.0 last December... and a -3.2 departure which was significantly watered down by the last 8 days of the month that averaged +5.3

Still a bit of a mountain wave signature on models Wednesday into Thursday-- strong winds slopping into more populated parts of Multnomah and Clark counties.

Sort of a surprise. With as persistently cold as it was before the final week, I was expecting this month to be a colder than last. Really shows how torchy that final week was.

It's called clown range for a reason.

Looks like EUG and SLE ended 2022 with small positive temp departures, but both -1.2F off of 2021. PDX had a similar

small positive departure and was -1.4F cooler than 2021. 

Medford ended up 0.1 temp departure.

Scoring in the last half of January would be a huge prize for us.  Hasn't happened yet this century, in spite of that time frame yielding some of our most extreme cold events in the past.  It almost always snows when it gets cold in that period as well.

January 2012?

A forum for the end of the world.

Very impressive pair to say the least.

I guess, but that was barely second half, and certainly not a classic like 1996 was.

The annual average for SEA for 2022 was 52.7.  Normal is 52.1 so that cold Nov / Dec combo really saved the day.

Saved the day?   Did it undo the ridiculous heat and drought during the warm season?    Don't think so.   Annual averages don't mean much.

Nice afternoon for Xmas demobilization.

Our house went from Christmas central this morning to everything packed in boxes now... just 11 months away until it all happens again!

Can anyone tell me where to find a list of water year (not calendar year) precipitation totals for regional stations such as EUG? I know I've seen this a million times, but now for the life of me I can't find it. All I can find is calendar year.

Go to the WRCC site and then copy the monthly precip grid into Excel.

Still a work in progress here. And it’s 10 months here. Covid seemed to alter my wife’s no-Xmas-before-Thanksgiving brain chemistry.

People are so hung up on the SSW.  I guess I kind of understand due to some events in recent years, but I'm afraid people are looking at it as being a magic bullet that we can't do well without.

Don’t be afraid.

You can use this: https://www.weather.gov/pqr/cliplot

Select Eugene, then Water Year Chart and you can select a year

I think it unfortunately only goes back to 2001

You can also use this http://xmacis.rcc-acis.org/

It goes back farther in time than the other site

Select Seasonal Time Series and then Water Year and then you can choose the station

In some years it’s more important than others. February 2019 wouldn’t have happened without the SSW.

First Asia. Then the western-hemisphere middle latitudes.
