December 2019 Weather Discussion for the PNW

[Timmy]

Major snow event for the washington cascade east slopes. Couple mesonet stations recorded 28 inches and 32 inches!! 18 inches for plain.

Fixed for you

[Shawn]

Storm total of 2.23" in Scappoose.

[Jesse]

Theres going to be some major flooding coming to some of the local rivers with the heavy rain and snow melt.

 

Not a lot of snow melt yet, fortunately. Snow levels look to come back down tonight as well.

[kokaneekidz]

It is fair to say/type that we are no longer in drought and the snowpack is coming around to normal in quick fashion. Meanwhile, 5-8 days out looks to be most fun for some foothill flurries and possibly snow in the North Bend alps and convergence zone environs. Bring it baby YEAH@!!! Happy Festivus for the rest of us

[Jesse]

My daughter(in Tigard)  has one of those small drains near her garage door and I’m so glad this didn’t hit you guys.  I think that drain would of been overwhelmed and flooded the garage!  Still a bit worried as this thing will sage south

 

Might be a good idea to get the drain situation fixed rather than banking on us never seeing a heavy rain event down here again.

[ShawniganLake]

Starting to think this event will overperform here... Over 3.5 inches of rain locally and another 24 hours of this is on the way.

I think the euro was showing storm totals near 6” for Tacoma. Could be inline with that.

[Jesse]

Yeah, it is going to get very wet down here still as the day goes on. Can already see the trends on radar. About to start raining here again. 

 

Hope so. Been a fun event so far in Washington. We were in Poulsbo the last few days and drove back down I-5 last night in HEAVY rain. Didn't lighten up until a little north of Kelso.

 

So far looks like we've picked up just shy of an inch down here since Wednesday.

Oregon says: Not so fast there.

 

I agree that the extended forecast looks favorable, though. Some more rain and mountain snows through the end of the month, lowish snow levels at times.

[Timmy]

This rain event Has been so much fun, making rainmen, sledding down wet hills, throwing rainballs. Scappoose is really performing well. Hope y’all down south get some tu.

SEA might be able to pull this out by going 4th driest to outside top 10. The difference between 4th and 10th is about 2.50”

[Jesse]

Radar trends looking favourable for the Portland metro this morning.

[TigerWoodsLibido]

0.72" Since Wednesday.  Looks like we are at 57F, on our way to the 60s today. Haven't had any steady rainfall since mid-day yesterday.  Had a +11.4F departure yesterday and still haven't had a high in the 30s this month.  Only 2.84" in downtown Eugene for the month so far and we should be at 5.06" by now.  This didn't bust the drought.

[Cloud]

Sitting under some moderate rain right now.

0.21”/hr rate.

 

1.53” for the day.

[TacomaWaWx]

I think the euro was showing storm totals near 6” for Tacoma. Could be inline with that.

That sounds about right...i haven't seen the latest euro precip map.

[Front Ranger]

If anyone’s curious, the wettest day for SeaTac is 5.02” from 10/20/2003. Nope. Not touching that today, but could easily be in top 10 per NWS-Seattle.

Easily top 5 for 24 hours.

[TacomaWaWx]

Not a lot of snow melt yet, fortunately. Snow levels look to come back down tonight as well.

Im hoping they can get as much snow as possible...looks good for more snow in the mountains on the forecast models coming up!

[TacomaWaWx]

We are at 2.13" here today...might have to go make some rain angels in the mud.

[FroYoBro]

Some decent gusts still to 30 mph as the rain has started again in Beaverton.

[TacomaWaWx]

Its officially the wettest day in seattle in 12 years...and its only 10am

[Blizzard777]

Might be a good idea to get the drain situation fixed rather than banking on us never seeing a heavy rain event down here again.

I’ve run a few test on it and it kept up but I know how quickly these things can get out of hand as it did last night here. 

I told her to just get anything she values off the floor of the garage in case. 

Also a good chunk of $$$ would be needed to redo that drain. Anyhow, we’ll find out perhaps later today it’s capabilities

A number of CFSv2 ensemble members from yesterday are jumping onto a potential sudden stratospheric warming event mid-January. I'm buying into this idea, and it's first going to start warming over Siberia in 1-2 weeks, and progress poleward.

  I think there's a chance. It would be around mid-or-latter half of Jan

A bar tender once pointed out to me once things get wet they can’t get wetter! 

[Chewbacca Defense]

Up to almost 1.5" up here in Bellingham according to my weather station.  Pales in comparison to what they are seeing down in Seattle but pretty impressive nonetheless.  Don't big AR's usually follow or precede big arctic events?  We didn't have one before soooooo.................................

 

 

Edit:  1.5" since yesterday when this started...

[El_Nina]

Looks like I'm gonna miss the rain by a few miles for several hours today. 0.02" since midnight, breezy

Hopefully it will verify.

[MossMan]

Currently at the rest stop on the east side of Stevens. Mixed precipitation falling here. I had to navigate around two different very large tree branches that were in the road just east of the summit. Roads are not great but not terrible.

Just moved past the 1” mark for the storm. If this was snow I would be upset being shadowed this much but I really don’t need a bigger dump of rain. The 12Z GFS looks like a mess through the end of the run. Hard to see anything to be optimistic about weatherwise at all.

Yea. It’s tough to even extrapolate anything good after day 16 on the GFS.

[Omegaraptor]

Portland misses record heavy rainfall which ends up going to Seattle, what do you know.

 

Of course the ensembles are making way for more dryshit around New Years. Back to split flow until April 15 then dry season.

Most areas down here at least got some decent rainfall out of this and more to come the rest of the day and tomorrow.

Ya looks like some ridging overhead around New Years....ugh.

Updated storm totals.

 

SEA: 3.53"

OLM: 4.32"

[FroYoBro]

Should be a pretty big difference in rain between HIO and PDX today. Rain coming down harder now in Beaverton.

[Brian_in_Leavenworth]

Some of you may know where Holden Village is or have been there (upper East slopes of the Cascades, west of lake Chelan, an old mining camp now a Lutheran retreat center open to all visitors).  They reported 33.5 inches of snow during the last 24 hours.

Cool spot, and that is great to hear!

How much have you seen so far?

Or is it turned to rain now?

[GHweatherChris]

4.8" now.
