Part I - January 2020 Weather Discussion for the PNW

[SilverFallsAndrew]

That arctic high in BC is really suppressing the mid week system. It is even further south. 

[Perturbed Member]

Wednesday system looks a tick south (or notch?)

[Deweydog]

Definitely a 2004 flavor to this, maybe just in the fact we never seem to completely dry out before the overrunning starts to move in.

[runninthruda206]

I feel like the sound might get decent snow sunday night that models aren't doing a good job showing yet

looks a bit north compared to the 12z

[Deweydog]

Conflicting reports!

[SnarkyGoblin]

Snow keeps getting better!! Lost another TOE NAIL!!

You should see a Dr.

[MossMan]

Conflicting reports!

Low solar.

[HighlandExperience]

looks a bit north compared to the 12z

Looks to be headed towards the mouth of the Columbia

[Weiner Warrior]

You should see a Dr.

I tried but I couldn't get my shoes on.

[Deweydog]

You should see a Dr.

There’s a reason they call you Einstein...

[Frontal Snowsquall]

OMG... here it comes

Here she comes!

 

[TT-SEA]

I see a strange dry slot west of the Cascades.

[runninthruda206]

It is a little bit south on this run! And looks too cold to snow or what?

[Deweydog]

Looks a bit north of the 18z two days ago.

[Weiner Warrior]

Its heading to Canada

[TT-SEA]

East wind is drying in this set up. In case you were not aware.

[HighlandExperience]

I see a strange dry slot west of the Cascades.

SW Washington will do very well.

[VancouverIslandSouth]

I see a strange dry slot west of the Cascades.

 

Dry east winds?

[wxmet]

GFS still trying to figure out how much the East wind gradient will affect the precipitation.

[Requiem]

Don't like that dry slot for Portland-- seems really intense too.

[Frontal Snowsquall]

The mid-week system is one sure slow mover.

 

[jakeinthevalley]

PDX radar is down until further notice.

 

I am not kidding

[runninthruda206]

That seattle donut hole has showed up on every single run... I'm worried and quite frankly disappointed - I'm being dramatic, but still 

[Deweydog]

PDX radar is down until further notice.

 

I am not kidding

Good sign!!!

[Cloud]

It's the offshore flow. It's eating up a lot of the moisture. 

You can see it's wetter where areas that has minimal east wind from locations like the coast and places like southern OR into CA. 

[umadbro]

PDX radar is down until further notice.

 

I am not kidding

It's a good thing money keeps being spent on fixing it instead of just replacing the D**n thing.

[MossMan]

I get the tingly feeling that next week will be like the majority of the Dec 2008 event where the moisture just kept streaming in almost every day that was under forecasted, at least for my area.

[Perturbed Member]

One of the few times being in the far western metro might help me I think. Should lose a bit less precip to the dry winds. Still surprised how little precip makes it to the ground on this run. Big juicy 98x mb low right to the mouth of the Columbia and not a ton of precip accumulates. 

[Weiner Warrior]

12 hr accumulation is showing zero as the low moves up the coast. Gotta be some dry a** air

[Requiem]

I'm a bit suspect of the GFS precip. Low placement is really what matters to me right now.

[Christensen87]

I believe the dry east winds will significantly decrease the snow amounts across Puget Sound unfortunately. The Hood Canal and eastern slopes of the Olympics will be buried though. Cold air still hanging around after the low passes though, so there’s that.

[Frontal Snowsquall]

I'm not too worried at this point. We should start having a better idea of moisture a few days from the event. EURO/EPS showed a lot of snow.

It’s a just a big ULL. As it’s modeled right now there isn’t much in the way of dynamics to focus lift.

[Chewbacca Defense]

My inch last night actually was not too sloppy!

You we’re doing it wrong!

[wxmet]

We need a weaker high to the north. Potentially mixing is better than very little precipitation.

[Omegaraptor]

Multnomah County Donut Hole???

[TT-SEA]

PDX radar is down until further notice.

 

I am not kidding

Unbelievable

[FroYoBro]

We need a really strong warm and wet storm to hit northern Vancouver Island.

Just goes to show that arctic highs can be RRR’s, too!
