October 2023 Weather in the PNW

[Rubus Leucodermis]

31.5˚F for a low this morning, freeze No. 6.

[umadbro]

T’was a good one this morning

[Tyler Mode]

Wow what an epic sunrise!  One of the best I remember seeing, especially in October.

[Phishy Wx]

I saved this Druncle map last HALLOWEEN (10/31/22) if only (btw: this didn't happen)

Map doesn't jive with longterm stations I'm seeing here.

I do have questions about the accuracy of ERA5 reanalysis. Though this trend is 1973-2022 as opposed to standard 1991-2020 climatology.

[MossMan]

Another red Phil by morning…Front Rangers take warning. 

Had a low of 34. Frost on the roof.

Had a low of 27 for my 6th freeze.  It’s 27 now with whispy high clouds over Jordan ridge.

[Phishy Wx]

got down to 20, almost 4 sub 20 lows in a row

A few pictures from this morning.

I got a question for y'all. If you could set up a weather station anywhere in the PNW, assuming the last century or so of records being accurately filled in, where would you put it?

I'd love to set one up near Cathedral Peak up by the border in the north Cascades. Good Arctic access, high alpine Cascade climate. Probably one of the more wild locations for snowfall in the world.

Estimated annual snowfall is only 20-30' up near Cathedral Peak which is a decent amount, but not overwhelming. Too far east to get the good snowfall. Now, where I would really love to see a weather station would be up in the Fairweather Range (even if that's not technically the PNW), maybe around 8-10,000'. Based on annual precipitation amounts that area probably picks up 10-13 meters of precipitation a year almost all of which must fall as snow. So probably 100 plus meters of snowfall or more than 400' of snowfall (4-5,000"+) annually. Makes a good candidate for the snowiest location in the world although 15 meters of water equivalent snow accumulation has been measured on the Southern Patagonia Icefield (Tyndall Glacier) so that may surpass southeastern AK.

Closer nearby, the mountains of Vancouver Island (specifically near Triple Peak northeast of Ucluelet based on PRISM analysis are estimated to pick up 12-13 meters of precipitation a year which would also be cool to see on a weather station.

so there one on the summit of Rainier?

[Phishy Wx]

Put one at Tim's House

I'd think that'd be above a lot of snowfall.  But great for winds and arctic air for sure!

On the summit of Mt. Olympus.

Recent streak of freezes as recorded on the east side of Everett at about 10ft asl. Interesting to see that a sensor about 20ft off the ground bottomed out at 24º but a sensor that was more exposed but on the ground had bottomed out at 28º.

[Meatyorologist]

Got down to 31.1F last night here. 6th in a row!

[SnowySeeker50]

Tried but just couldn't get below 33 degrees this morning. Some stations nearby did while others read higher.

That Patagonian ice field is something else. Such a stupid amount of snow accumulates there that it spills over helplessly on all sides. That looks like an area that will always recieve ridiculous amounts of snow, no matter the climate situation or the winter weather pattern setup.

Triple Peak is an excellent choice for our area. I chose Cathedral Peak due to the better access to Arctic air and fluffy powder. Some of the stations to the west even around 7k ft have a problem switching over to rain from time to time during the winter. That'll almost never be an issue as far east and high up as Cathedral Peak.

Got down to 31F for our 5th freeze. Doing well so far.

Happy Halloween!

I don't think so, but there may be one at base camp around 10k feet up. Putting one on the summit was staring me right in the face. Very easy choice! Given its overwhelming prominence, Mt Rainier essentially acts as a 14k foot radio tower w/ little to no airmass modification as Pacific winds slam into the mountain headfirst. Sampling 14,000 feet into the atmosphere of a midlatitude Pacific climate at all times of year is any weather nerd's dream. Add some upslope enhancement to boot? Some insane numbers up there for sure.

I'm really curious what the Summer nighttime lows are like in the east summit crater? A local basin in an ice field above 14k. I bet it would put Peter Sinks to shame. Subzero in July? You can really let your imagination run wild with a location like that.

Low of 31 here this morning. Freeze number six.

[TigerWoodsLibido]

Going to close out October with a respectable 8 straight days of below normal average temp departures. I have a feeling we will see at least 1 more respectable stretch of cold this regular season. Doesn't feel like a traditional nino locally the more I think about it.

I expect it will be quite Niño-like once the new year arrives. Until then, there are decent chances for some fun in November or December.

And it’s fine. Most of us are coming off a string of snowier-than-average winters.

I just want my pond to fill this year. Snow would be a bonus.

Wrong direction. I'll get shadowed hard by most of this precip.

Oh man, it’s going to be one of those seasons where I’ve just got to add your ip to the table for a solid six months.

Yeah the niño is very healthy and well coupled, contrary to what some forecasters have said. But it isn’t until Jan/Feb that the middle latitude response stabilizes, so there’s room for intraseasonal variability in Nov/Dec.

Downtown Seattle or Seatac. Honestly. Probably downtown Seattle. I'd like 100 years of continuous, accurate data for Seattle instead of all the gymnastics we do for Seatac which itself only has a short history.

This checks out. It’s our 2nd wettest month after December, though January is a close 3rd. 

[HuskyMaestro]

48F and cool. Hope you’re all having a good one. Not too much trick or treaters, so more candy for me! 

Threw on random things, now I feel like Jack Skellington looking at snow and Xmas lights for the first time
