November 2017 PNW Discussion Thread

[TT-SEA]

My temp here has been rock steady for the past two hours.

 

That band of moisture from the coast is sliding south of King County.   It will not be moving northward much.

[ShawniganLake]

1970-71 was a huge one up there too. Really huge in fact.

74” at YVR. Snowiest ever I think?

 

83” here.

[snow_wizard]

Nice mild day down here. Hoping we break 50 again.

 

Just like a different world between SEA and PDX with this cold snap.  So far this cold snap has really been odd in that the min temps have been ho hum, but the max temps have bee historically cold for this early.  Very different than our typical cold snaps during this century.

[Guest happ]

He only meas climo for observed weather here.  The setup over the NE Pacific will be pretty abnormal.

 

Am happy w/ zonal flow including periods of rainfall.

[SilverFallsAndrew]

Sometimes the temp goes up during the daytime.

Yesterday was only in the mid-upper 40s.

I've been surprised but recall snowfall in Portland when Seattle stayed bone dry.

[SilverFallsAndrew]

I see December possibly being a lot like 2007 or 11

Helps being north of the lows.

 

It takes a lot to get a low to come in south of Portland this early in a major offshore flow pattern.  Even with the beast airmasses in 1985 and 2010, the lows went just to the north of Portland. This one has been pretty typical for November climo, IMO.

Happened too often last winter.

A strong north/south gradient is very typical in November events. Especially this early in November.

 

Even then, it’s been chilly down here compared to climo. Most locations are 2-3 degrees below average for the month to date.

Yeah...SEA has a tendency to pwn Portland in November events.

[BLI snowman]

Yesterday was only in the mid-upper 40s.

 

Definitely helped to clear some anxiety and add some minutes to my life!!!!!1

[Jesse]

PDX’s average max for yesterday is 57, and they only saw a high of 47.

That band of precip to the SW is looking really impressive at this point.  Might be fun!

We'll always have 1977

We were hiking on the Salmon River trail near Welches yesterday, so I didn’t even realize until getting back into reception that evening.

During those past Portland-only snowstorms was the temp in Seattle noticeably warmer?

Picture Venice Beach during a Santa Ana.

[SilverFallsAndrew]

Yeah November 2006 is another example of Seattle - North doing very well. 

[wxmet]

There's a nice band moving towards the Pugent Sound from the west. Should produce some nice rates.

35 with a dp of 35 hope it's snow that falls

[TigerWoodsLibido]

I remember snow falling near Grand Ronde during that 2006 event. Falling here at the same time as it was at the Packers-Seahawks game that evening.

[SilverFallsAndrew]

2.20" of rain so far this month. A good start.

[Deweydog]

#kold

That's 10 degrees below average!

[TT-SEA]

Won't reach up to Bothell.

 

I have been watching a band approach here and its over me now but its not that impressive.   Snow is not accumulating now and its falling off the trees.   

 

Radar is also in hyper-sensitive mode so things look more impressive than they are in reality.  

[TigerWoodsLibido]

That's 10 degrees below average!

Yup. Avg hi here yesterday was 56 & we were 49. 7 below. Certainly colder than avg. Hope it's a good omen.

[Jesse]

The sun is shining here but there are some very dark klouds to the north. 48 currently.

[SilverFallsAndrew]

Yeah I know some places around Salem and Eugene had minor accumulations. Nothing like up north though. 

[SilverFallsAndrew]

41 here

[Deweydog]

49.7 below sounds a lot more impressive than just colder than avg.

[Timmy Supercell]

For now, more wet snow. Woke up around 8am with some on grass. Maybe tonight some real stuff.

[wxmet]

NAM 3km 12z picked up on the band from the west:

Couple degrees below average.

Wednesday should be colder. Pretty decent setup for a very early

[wxmet]

[ShawniganLake]

35 and sunny here with a light north wind. Nice day.

 

Most of the moisture last night went south of here. Hope that’s not a trend for every storm the rest of the winter!

[Jesse]

I was thinking the same thing. Right now looking like some chilly offshore flow with a system moving in over it.

 

We drove up to Govt Camp yesterday after the hike and it was VERY wintery!

NAM 3km 12z picked up on the band from the west:

 

Seems like the 3km NAM has handled things pretty well the past couple days.

[Jesse]

12z Euro plays with a colder pattern for us again days 7-10. Maybe the Thanksgiving believers will end up being on to something after all. Timing wise it seems unlikely, though.
