Friday-Saturday. Seattle south ~2". Seattle north to Vancouver 2-6"

http://maps1.pivotalweather.com/maps/models/gfs/2017013100/168/500h_anom.na.png Winter returns with a vengeance?

18z ensembles leave the door open for a trend to more Euro and Canadian like solutions in the future.

Only off by 0.1 F considering data through Jan 29th. 33.1 predicted 33.2 actual as of Jan 29th. 33.6 final value assuming NWS forecast is correct today/tomorrow. No change as far as it being coldest month since Dec 1985 and coldest Jan since 1979.

Frozen Snake River today Cap Cloud on Mt. Hood The rugged Mtns of Central Idaho

Don't forget the 3 fingers of scotch!

With another major snowstorm just starting to hit in the last frame. Jan 1950, in February!

Massive ensemble improvement... Operational was not an outlier...

I think he's trying to make umadbro.

We've seen bigger runs in 2014, but I'd take these in a heartbeat this year!

Oops, my bad. Rip City out there now! 2" per hour weenie band stuff, OMG Niko! It's wild!! Edit - massive dendrites too! Sick out there right now!

Looks like my first Montana snow storm since I moved is on my doorstep here in Bozeman. I'll definitely be in the sweet spot as the front stalls over me this week. Expecting 12-18" beginning tonight through Thursday. Should be a fun few days!

Friday looks like our chance around the Sound. The more cold air pushes in over the next couple days, the better chance of snow we have then. So yes, the 18z actually is an improvement. It shows an inch or two for Seattle and 2-4 for the SW Interior and Hood Canal in fact. http://www.tropicaltidbits.com/analysis/models/gfs/2017013018/gfs_asnow_nwus_21.png

I think it was in fact raining moderately near his eyes.

You weren't expected to but I get the hoping for a last minute bump south. January 1900 Chicago had The Triangle of Dearth:

Wow, this Euro run is just worlds better than the GFS days 5-10. Keeps the blocking ridge stronger and thus limits the undercutting. Would be really nice if this were the start of a trend.

100 miles east on the Euro on day 5 and it's a daddy blast. http://stream.ecmwf.int/data/atls02/data/data01/scratch/ps2png-atls02-95e2cf679cd58ee9b4db4dd119a05a8d-2bbPpJ.png

The sun and warmth is feeling a little rejected right now... It had its bags packed and was getting ready to migrate up at your request.

Big shift in the 12Z Euro. North sound looks snowy for the weekend.

My dad would say "shut the **** up about the daffodils! It's the middle of inversion season!"

Just Phil.

12z GFS...looking good for WI/MI posters...finally, the snow hole on the north side of MSP will get covered.... http://www.nohrsc.noaa.gov/snow_model/images/full/Upper_Midwest/nsm_depth/201701/nsm_depth_2017013005_Upper_Midwest.jpg

Cold winter!

The progression being shown is much more favorable. Let's hope it works out.

Totally insane to see all three models change so dramatically on just one run. You can easily the detail that makes the progression so much better also. MJO may save our butts!

I agree, the actual threat from nuclear power plants seems pretty low to me all in all, looking at a history of incidents...I'm pretty sure that coal mining has killed far more people than Fukushima and Chernobyl have.

Not this time.

George Michael is back from the dead!!

Well this is different, the 0z GDPS doesn't show any significant warmup, but rather a weekend long snow storm for the North Sound / Island. http://maps3.pivotalweather.com/maps/models/ggem/2017013100/108/prateptype_mm.ca_w.png

What is a WHEM wavetrain? I Googled "WHEM wavetrain" and the only result was one post you made on this forum.

This should bring snowwizard back. Heights crashing into weekend.

I agree. It is tough to let it go when Phil keeps flinging insults though. Especially when it is so obvious to everyone that he is being dishonest. The same thing used to happen back when he would compulsively lie about his location. The closer you got to the truth the more venemously he would lash out.

Bush just looked bored to me and Laura wouldn't let him bring his Gameboy.

Pls, don't "dry air" on our parade

I have to disagree! What the Euro tells me is that Portland is going to get even more snow this weekend. And it's going to be even more epic-er than the January event. Dare I say...it will be YUUUUGEE!!!! Biggest Snowstorm ever! 1.5 million inches!

Why have you posted it so many times then?

The Euro just had to step in and give us northern folks some hope... I had my mind made up winter was over damnit

Some noticeable steps toward keeping the northern stream stronger mid-long range on the 12z Euro ensemble mean.

Its gonna be a fun February in terms of tracking storms. My forecast is already showing signs of snows down the road. Hope they verify though.

WWA was just included for SEMI From TWC: WINTER WEATHER ADVISORY IN EFFECT FROM 10 PM THIS EVENING TO NOON EST TUESDAY... THE NATIONAL WEATHER SERVICE IN DETROIT/PONTIAC HAS ISSUED A WINTER WEATHER ADVISORY FOR SNOW, WHICH IS IN EFFECT FROM 10 PM THIS EVENING TO NOON EST TUESDAY. HAZARDOUS WEATHER... * SNOW DEVELOPING LATE THIS EVENING, BECOMING MODERATE TO BRIEFLY HEAVY AT TIMES OVERNIGHT, THEN DIMINISHING TOMORROW MORNING. * SNOWFALL ACCUMULATIONS OF 2 TO 3 INCHES EXPECTED BY SUNRISE TUESDAY, WITH ADDITIONAL ACCUMULATIONS AROUND 1 INCH DURING THE DAY. * TEMPERATURES IN THE 20S TONIGHT

Stupid ******* idiot hippies.

Not sure yet Tom. Accuweather is being it's typical glitchy self and is only showing 7 days of output instead of 10.

Well Trump's main skill in life is that he knows how to negotiate from position of power, which is what he is doing. Ultimately public opinion is malleable until it creates serious discomforts to people's lives, and likely won't have much of a consequence for him. Given that he has no idea about the issues that he is negotiating about it's a matter of time before he does something that will cause that and result in impeachment or electoral consequences(war, trade war with china and/or economic recession as direct result of his policy, and some other thing I can't forsee at this point). But I am not sure that Trump, the blind man in this game, will step into the landmine with irreversible consequences which he can't lie about later and say he was just kidding and it's back to business as usual. I am not going to be clamoring around that Republicans will impeach him right away or after midterms of 2018, but it's hard to see him making it past 1 term, especially since coalition is already brittle and his victory was razor thin.

As long as they accurately record the weather conditions at the time of deregulation I'm all for it.

Today could end up pretty chilly, PDX still holding at 38 with heavy overcast.

We really need a face palm emoji here.

I've never understood why crowd size matters. Obama won DC with 92% of the popular vote. Trump might have managed 20%. The majority of attendees are probably living within about 3 hours of DC, ergo crowd size will be smaller regardless of national popularity (not saying Trump is anywhere as popular as Obama).

The deformation band doesn't look very impressive anymore on the NAM. http://www.tropicaltidbits.com/analysis/models/namconus/2017013012/namconus_ref_frzn_nwus_47.png 12z WRF http://www.atmos.washington.edu/wrfrt/data/2017013012/images_d2/or_snow48.84.0000.gif Pretty sure this will all play out a bit different from what the models are showing anyway. They often seem to struggle with these bands.

Oh philbert

Sure could be wrong... AO will drop in the short term briefly what happens after that is anyones guess. Waiting for the split reminds me so much of last year.
