I had a frosty vehicle 10yrs and 1 day ago! 2013-2016 was quite a terrible stretch for my area. Sure we had little snowfalls here and there but nothing substantial. 

[ShawniganLake]

The official station for Shawnigan Lake hasn’t updated since November 3rd.  I’ll be disappointed if the station doesn’t come back online.  It has very consistent records going back to 1911

[TacomaWx]

Rain snow mix this morning here at about 900’ on the raging river. There was some wet snow when I was up here yesterday afternoon too.

7 years ago on this day we had snow in Wood Village. Wish we had some now

Drizzle and 37 here this morning.

I guess they also close schools in Alaska when it snows as well! Their situation with the prolonged wet snow reminded me of my favorite…November 2006. It’s odd to think that some smuck like myself living an hour north of Seattle is more prepared for cold/snow no power for days than these people living in Alaska. 

 

I ended up watching some of their other videos to see what life is like in Alaska.  The video you posted here was from a couple weeks ago.   Lots of tree damage from heavy wet snow followed immediately by cold.   A few days ago they had 70 mph wind with sunshine and that finally cleared off all the trees.   Interesting that summer was the time they were most down talking about endless rain and insane mosquitos.  They posted a video from July this year and they were pretty depressed... they said winter was 8 months long and now its cold and raining all summer.  They also mentioned that they like their videos to be fun and happy but the rain was wearing them down.   Sounds like they are leaving Alaska now... in their last video they talked about revealing where they are moving next and said it will be totally different.   Now I have to check back and find out where.

As someone who has spent the past 20+ years in the commercial aircraft interiors business I can speak to that.

Short answer, It's required by law.  Inevitably someone will try to smoke, and authorities want to minimize the chance that the fool throws a lit cigarette in the garbage can, which will in all likelihood be full of flammable materials.

Most "ashtrays" now are just big enough for 1 cigarette.  Last lav design I was a part of, we initially thought/hoped we didn't need one  this day and age, but a quick consultation with our certification experts and we found out that was not the case.

 

The waste can is designed to contain the fire for a period of time (not that I would recommend testing it) should some moron decide to toss a lit cigarette or match in there.  A CRAP TON of design effort goes into these waste compartments to achieve this, and they are rather expensive.  We put an extinguisher system in one of the waste compartments, but I can't remember if it was the lav or galley.  All of the materials used in the aircraft are designed to self-extinguish, and about 10 years ago it became a requirement to test the toxicity levels of the smoke.

All that said, I highly recommend not smoking in the lav or tampering with the detector.  You will have nice people with guns and badges waiting for you at the nearest airport who will put shiny bracelets on you and ruin your trip.

For the last design I was a part of, the engineers did a fire containment test burn, but did not conduct the test far enough from the building, and ended up filling the building with smoke.  OOPS!

 

I guess if never noticed it when white plastic like that, this one stuck out on the embraer.  cool insight

Disregard drizzle.   Now see clear skies and a thin crescent of a moon out there.

Must not be real Alaskans. One of my co workers is going to Alaska on Monday and has been complaining for a few weeks about it. She’s coming back Wednesday, I’m sure it will be fine…

The snow they had at the beginning of November was pretty unprecedented, and heavy wet snow as you mentioned which led to about a week of no school in the area of anchorage another one of my co workers lives in.

[High Desert Mat?]

Woke up to an amazing 1/4” on the ground. Temp is 28

[MossMan]

Looks like a cz right over Lake Goodwin, could be getting some mixed precip there I bet. 
37 here currently.

06Z Euro and 12Z GFS snowfall for Saturday’s event.

Either 2nd or 4th shade of grey for me…Time will tell!

Some hail last night.

A number of aircraft fires have been caused by this, which is why they both have smoke detectors in the lavatory and literally make a Federal case of it if you are caught smoking in one.

[MR.SNOWMIZER]

The gfs fv3 is showing snow out here as well. If the euro still shows it today it will probably happen. I have seen events like this that were borderline but with massive precip available dump huge amounts of snow here. If it were coming at night it would be game on. The daytime heating is almost nothing right now so that will help.  I'll say 3 inches here Saturday.

The Goofus has me in the blue. Unfortunately, it’s the Goofus.

The short-term models show both of us getting something as well:

[MR.SNOWMIZER]

Impressive to see the euro show 3 inches here and not one mention of it in a forecast.  If moderate precip rolls in with temps in mid 30's it will turn to snow here guarantee it.

NWS is setting itself up for some egg on its face, similar to (but not as dramatic as) that big dump Portland got last February.

12Z GFS and 12Z GEM show basically dry weather all of next week through next weekend.

Min of 32.7˚F overnight. Now 34.0˚F.

[Dave]

Picked up another dusting of snow. It was colder this time, so it at least stuck everywhere. Looks like I won't be shoveling the sidewalk on this trip to Bend.

[MossMan]

The northern edge of the CZ a bit ago when I was driving to work. 

[Dave]

The squirrels in Bend are huge. Way bigger than the ones in Eugene. A Cooper's Hawk hung out for a few minutes in a tree yesterday.

[Sunriver Snow Zone]

Waiting in the lift line at bachelor right now, today is the re-opening day. It opened last Saturday but it's been closed every day since then, now it's opening back up. Pretty nice day up here, looking forward to ski.

 

How are the chances looking for a widespread cold or snow event on Christmas? Impossible at this point or still possibly but very unlikely? I haven't been paying much attention to the long range these last few days.

Pretty unlikely. Maybe Christmas 2024. Would be nice to have a huge arctic blast to celebrate the 100 year anniversary of the big 1924 event.

Looks a little too distilled for much in the way of a decent inversion. Lots of blah 49/38 type days. Then we mix out with some fresh drizzle just as the high pressure begins to strengthen a bit.

[ShawniganLake]

The pattern leading up to Christmas is basically the inverse of a cold pattern here.  Just a beast of a trough over the NE Pacific.  Would likely be warm and wet with a possible stormy pattern if the trough shifts east slightly.

I would say that pattern looks extreme and unlikely to verify but the 00Z EPS was not that different.

Check out New Year's 1924, which I've always seen as a pretty overlooked blast in what was a moderate Nino season.

Portland ripped off 7 straight subfreezing highs and Eugene landed itself a 22/8 day. Even Newport managed a 32/10 day on the 1st.

Just a drop in the bucket for back then, but that would make some serious waves if it happened in this day and age.
