October 2018 Weather in the Pacific Northwest

[wx_statman]

Readings as low as 5 degrees above zero this morning in Maine, including a monthly record low of 10 in Houlton. Winter is coming!

[MossMan]

Breezy!

[BLI snowman]

Looks like I'll finish with about 1.70" today. Not too bad.

[TigerWoodsLibido]

First band came through now it's stopped. Sorry to the folks up north with what looks to be some issues.

Really weird year here on the east coast. It was an insanely long summer, but it ended with a single cold front on October 11th. Switch flip. Doesn’t usually happen that way.

 

Same thing happened with the transition from winter to summer...flipped in the blink of an eye as the calendar turned over to May. Yet another skipped spring.

A significant (subseasonal?) NW-Pacific anticyclonic regime is looking increasingly likely during weeks 2/3.

 

Poleward heat/mass flux is going to be drastically reduced during this time. The result will be a strengthening of the polar vortex and a buildup of dry, frigid air across the Arctic (and high latitudes in general). Sort of like the summer pattern, which produced the record breaking cold across Arctic Canada (where exactly it ends up this time is debatable).

 

Assuming the next round of wave amplification occurs near/just after Thanksgiving, in there could (in theory) be a prolific Arctic air dump somewhere in the lower-48 to open the winter. Because the cold is really gonna start loading up north next week.

Yesterday’s 1.88” of rain is my 2nd heaviest one day rainfall in October. The only wetter day was 2.08” on the 22nd in 2014.

What’s your thoughts on potential mjo to develop west if the dateline end of November/early December? Do you see amplified pattern returning ?

[Blizzard777]

3.43 for the month so far! Pump under the house should activate soon and continue until next spring

[TigerWoodsLibido]

As usual, EUG in the screw hole with a measly 0.41" storm total.

Had no idea how bad it was until I moved back down here.

[Esquimalt]

Around an inch for a storm total here. It’s been a while since we had that much rain so I’m happy, but nonetheless wish we got more.

Thunder away !

A few claps out there

Hawks kicking off in the Motor City in a half hour!!

[ShawniganLake]

Driving back from Kamloops this morning. Major dump of snow on the Coquihalla currently.

So much for no cold until after New Year's!

Trucks and cars spun out everywhere up here. Looks like they are about to shut it down northbound on hwy 5.

[Perturbed Member]

Got about 1.62 in through Firday night to now. Not bad.

 

 

Snow level making its way down gradually, looks like it is still about 6500ft in the central OR cascades

 

[TT-SEA]

SEA has had 2.22 inches since Thursday... and the Snoqualmie Valley station out here is now over 4 inches since Thursday.     

 

And there is very heavy rain moving in again.   

 

Definitely a wet October now... and there is much more coming through the end of the month.

Looks like you may catch up with Phoenix soon.

You must be in Eugene again. With happ gone, the California thread will be at least 75% my posts.

[TigerWoodsLibido]

Losing to the Lions would pretty much end the Hawks season.

Nice to have, you, Dolt, and yours truly representing the south valley.

[MossMan]

Just over a half inch last night...had a break this morning to do some outside cleanup, now dumping buckets again!

[Geos]

It gushed down rain last night here, complete with wind. Was on the coast also at Copalis (razor clamming) and was a real soaker until about 8:30. 2.03" and increasing. Now pouring again.

[MossMan]

The Seahawks are kind of fun to watch again.

[Deweydog]

Mixing it up nicely.

[TT-SEA]

I was about to post the same thing and then remembered that i every time I say something good about them... a catastrophic injury follows almost immediately.    

 

I will just say something in general about the NFL... when you have a running game then everything else seems to work.

[Jesse]

Starting to be a pretty impressive stretch of warm lows down here.

[Jesse]

12z Euro looks active. Definitely a wet Halloween though.

Wet Halloween has become a given now.

Still not too late to book a neighborhood on the east side!

[Jesse]

Lots of convection popping up around the metro currently. Surface temps are still pretty warm compared to the upper level airmass as well, so some decent instability out there.

[Deweydog]

Nice day!

 

Wet month!

[TigerWoodsLibido]

Hawks are gonna blow this aren't they?

 

Edit: no, the Lions are a bad team.

[Phil]

*If* the coming pattern doesn’t over-strengthen the PV and increase static stability the tropics. It’s a 50/50 proposition, I think.

 

Such a tough call. I have no idea which way it will go.

[Perturbed Member]

Some impressive downpours from these convective cells. Dropped close to a half inch of rain in a hurry here. Should cross 4 in of precip for the month.

[TT-SEA]

Wow. Ballsy call. Love everything about it.

 

 

It looked like he had the option to still kick it away... and looked like he was debating doing that and saw the opening to run.  

[TT-SEA]

Good Lord... what a schedule for November.  

[Guest Dome Buster]

Should get out of next month 2-2 which I will be happy with. 6-5 going into december with a softer schedule. 10-6 and a wild card spot is my prediction.
