February Snowfalls 2/10-2/12, Part III & IV

[jakerepp]

Just starting to see flurries at my office by Boeing Field (Tukwila/SEA boundary). What time should I head home? 

[jcmcgaffey]

It’s warmjng up quick. Did the same thing yesterday though and then stuck at 33-34 for the rest of the day.

[TT-SEA]

Wednesday morning...

 

[seattleweatherguy]

Tomorrow afternoon... around 40 in Seattle during the afternoon.

 

What's causing the rise in temps a low more north or just moderating temps? For tuesday

[Front Ranger]

Total snow through 4 a.m.    That is 9 inches at SEA.

 

 

If that verified, I believe it would push Feb 2019 up to SEA's third snowiest month on record, behind only Jan 1950 and Jan 1969.

Maybe the WAA will get stuck in the swamp if the ECMWF is to be believed. We’ll know soon.

[Rubus Leucodermis]

Snowing again on Bainbridge.

[jakerepp]

Related question for all of you with more knowledge that me: What is the biggest factor in snow falling when surface temps are above freezing? 

[TT-SEA]

4-10 a.m. on Wednesday... big shift south from 00Z run.    Which means colder air is also pushing in faster.

 

[snow_wizard]

OMG!  The ECMWF is colder this evening.  Major snow!

 

Here is a map showing how the east wind will wall off the south wind at the King / Pierce County line.

Dew point or precip intensity.

Would love this to verify. If this happens they will almost surely shut down the office for tomorrow. 

[TT-SEA]

Wednesday afternoon.    Actually a bit warmer in the Seattle area that day than the 00Z run as precip is much farther away.  Looks like upper 30s and its almost totally sunny as well.

I just feel that last nights weird procession of events threw a major wrench in their beliefs about today. Hopefully last night was just a DEAD CAT BOUNCE and today and thru tomorrow will be epic in terms of the whole Olympia north and environs just get plastered with 12-24 inches of new.

 

While I would love to see that too, I wouldn't hold my breath.

Yep the WAA gets stuck in the swamp and we get gradient CAA which would help immensely.

[Front Ranger]

Hoquiam down to 33 with moderate snow and NE wind continuing.

 

OLM also down a degree to 31.

[XLVIII43to8]

If I was in Chehalis I would be feeling scrwed.  Just one little hole of rain there.

 

 

Looks like it's snowing there now 

[jakerepp]

Snow quickly picking up now. Flakes getting larger. 

[TT-SEA]

Winds tomorrow morning... the southerly wind meets the Fraser outflow wind up around Bellingham.  

 

[GHweatherChris]

Approaching 2 inches, perfect dry snow falling!

[snowbustcity]

Snow quickly picking up now. Flakes getting larger. 

 

Really? And you're in Edmonds? Nothing in NE Seattle at the moment.

[Gummy]

Approaching 2 inches, perfect dry snow falling!

 

That's more than the nws called for isn't it?

[tjb723]

Snowing lightly here at the moment, started within the last 1/2 hour. Temperature has ticked up from 31 to 34 currently.

 

Last night's storm was good for another 4.5" here, total snow depth currently 10".

[BLI snowman]

Through 10 a.m. tomorrow.    It shows 36 or 37 degrees in Seattle tomorrow morning.

 

 

Probably our best chance for something down here. Which isn't saying a lot.

[jakerepp]

At work in Tukwila. Must've missed my comment from a few minutes earlier 

[MossMan]

That looks fantastic! Though it appears my area will be getting shadowed a bit today/this evening. Can’t have it all though I guess, haha

[Gummy]

Cliff Mass still saying only a few inches for most of the central and south puget sound, guess he isnt buying the Euro numbers.

[snowbustcity]

At work in Tukwila. Must've missed my comment from a few minutes earlier 

 

Ah right, I saw that

[snow_wizard]

Looks like it's snowing there now 

 

I guess the radar precip type is wrong.  This bodes well.

[XLVIII43to8]

Pretty snowy through 4AM...

 

Is there any chance this model actually pans out? 9" at Boeing Field and SeaTac??? What would we need for this to happen? South winds to die down? The low to stall or move south? Strong easterlies in King County?

He trusts the WRF over the ECMWF.  Since the Christmas snow last winter I'm a Euro man.  It nailed that storm dead on.  Only model to do so.

The wall of east winds that are being shown.  It kills the south wind.

[snow_wizard]

That radar looks formidable.  Going to be fun!

[Frontal Snowsquall]

Some strong cells making it's way into PDX Metro.

 

[MR.SNOWMIZER]

Cliff Mass is wrong. Again..

[GHweatherChris]

Approaching 2 inches, perfect dry snow falling!

WWA says up to 3 inches possible.

[TT-SEA]

No real cool down from the 00Z ECMWF on the new 12Z run for the Wed-Sat period. Might be a tad warmer actually. Lots of low 40s from Bellingham to Eugene.

[Poulsbo Snowman]

Light to moderate snow just stated in Poulsbo.  31 degrees.

[GHweatherChris]

Snowing hard and sticking as of now in Westport according to my parental units!

[runninthruda206]

Might be our last snow of the winter before it changes do rain! Enjoy it
