December 2019 Weather Discussion for the PNW

[Timmy]

We really need that sixth inch. Fuuuuuuuuck.

speak for yourself I can only handle 5

[Jesse]

Mark twisted the sun angle knife tonight. Sunset was a minute later today than yesterday according to that washed up windbag.

 

You are pretty consistently one sided in your mockery for someone who makes fun of people for being consistently one sided in their mockery.

That’s what he/she/x said.

[TT-SEA]

Matt... someone is whining about your posts again.

[Jesse]

Euro says we may get our six inches by Sunday morning! 

 

Rain event pretty squarely over NW Oregon and SW Washington on this run.

 

[Dave]

It's all about what you do with it. There's nothing wrong with 5 inches.

[Deweydog]

[Jesse]

Mountain snow not quite as good on this run, though.

 

[Dave]

I like Rob, frogs, and deep snow.

 

Fred, on the other hand, is probably Satan. I mean have you ever seen them both together at the same time? I think not.

[GHweatherChris]

No need for that kind of rain up here, pattern is shitty.

Koalas have two penises. Beat that.

Don't make me post the koala copypasta again.

 

Ducks have corkscrew penises.

F*cking Seattle. And Dunsmuir, CA.

[Deweydog]

Speaking of penises...

 

Has anyone seen the commercial for Peyronie’s Disease with the vegetables?

[Phil]

[MossMan]

Very wet then very frozen? Could be a 1990 redux! I remember flood waters in the area that didn’t fully recede before turning cold and freezing over.

If it rains in the mountains and melts snowpack, is that beneficial or detrimental?

 

Just trying to learn the rules here. Don’t want to get mutilated by the rain misers again.

It depends on the season. High elevation rain that melts the snowpack is pretty much useless this time of year or really any part of meteorological winter, since the reservoirs will simply be emptied for flood control. In mid/late spring, it is fine because they are trying to refill the reservoirs.

Not great. Though the snowpack can absorb water and store it when things re freeze. Up here there isn’t any snow in the mountains to melt so it wouldn’t make a difference

Yes, pretty much every year the snowpack absorbs plenty of rain. I've also seen large ponds form on top of the snow when it became fully saturated. Looks pretty cool actually, but it has ruined a couple of snowmobile outings.

[Phil]

Interesting paper. “Regional atmospheric circulation shifts induced by a grand solar minimum”.

Interesting. And good to know.

February 1996 and December 1964, two of the most prolific floods down here in modern times, were taken to such a level by the combination of the heavy rains and melt off of low level snow pack.

 

1996 in particular had a pretty insane amount of snow at foothill elevations after a good run since mid January. I think I remember seeing a number of 10-15 inches of liquid equivalent from the melting snow in the higher elevations of the coast range.

[Dave]

Here's a random pic of a snowmobiling trip gone wrong. This was on a road next to the snopark near Santiam Pass. When we saw this, we knew we had made an error.

 

Btw, the water was about 14-16" deep. We were in a big truck, thankfully.

South valley bros absolutely killing it with the marsupial and monotreme facts.

In Asia that's above average. lol

The way weather dot com puts it I have a 20% chance of snow in the next 10 days., I will take it!

12z Euro had 14.2" for me on 240hr total accumulated snowfall.. Seems to be an outlier but we'll see for sure in later runs.

 

Of course on a local Klamath Falls facebook group this was the first model image anyone shared in almost a month. Go figure. 

And hey, I finally found the site that outputs these. Bookmarked.

You can't do much with a half inch, but I'd take it and explore the possibilities.

Oof I think that's the 12z

[Phil]

Third consecutive EPS control run to develop a cataclysmic block somewhere in the NH.

 

This one is so massive it helps drive the cold all the way into BC/Alberta even though it’s more of a NATL feature.

 

[Christensen87]

06z GFS brings the cold in again NYE. So much back and forth as usual.

[Phil]

There it is. This is what I thought the 00z was gonna do until it went shroomin’.

 

Look at that fidget-spinner PV just idling over the Yukon/Western Arctic and getting bled dry. Love it.

 

[Blizzard777]

To go with Phil’s fun map

Brrrrrrrrr!, this is the way to bring in the New Year along with some white stuff
