It doesn't take much snow to make a huge difference in how things look.

 

I'm disappointed we haven't done better, but Sunday night / Monday morning has a shot at something good.

That time period could be interesting. Plus it is very close, don't have to wait 10 days. It has been awhile since we have seen a genuine arctic front with snow come through these parts.

In spite of the GFS operational not being quite as pretty as some earlier runs the ensemble is very cold. Probably the coldest yet with this possible event.

Normally the Central Puget Sound does well with Arctic fronts. IMO that's when getting snow counts the most.

Snowing!!!!!!!

00Z ECMWF does not show any lowland snow for Sunday night and Monday morning (for our area)

 

The 12Z run showed at least a little lowland snow in that timeframe.

Booooo.

AT hour 96 the EURO is a little colder than last nights 00z.

[Cold front]

Nothing better than an Arctic front coming through during the daylight hours. Love when the temps plummet and the winds start cranking. Haven't seen this is many years.

That is to bad.

It does show a little over SW WA on Monday afternoon.... but nothing for the Seattle area.

WRF is showing snow for Central King County on Monday. Probably smoking dope again.

Great writeup by Albrecht (Jaya) at NWS Seattle! Really looking forward to next week!

[MossMan]

Really coming down now, everything turning white!

00z = Epic fail!!!!!!

Boooooo!! How did the Canuck look tonight? I didn't see much posted about the GEM

[SilverFallsAndrew]

Ouch

[MossMan]

KING EURO!!

[SilverFallsAndrew]

Hr 192 trending in the right direction...

Looks like it's working on a big snowstorm for northern Washington and SW BC end of next week.

[MR.SNOWMIZER]

3 inches here. 27 degrees

[MR.SNOWMIZER]

Anything over 48 hrs in the models right now is pig manure

[Winterdog]

Snowing pretty good here now. The Euro just needs a couple tweaks the first part of the week. Thursday looks like a good snowfall Seattle north. This snow actually is acting like real snow and not the ice blob snow I'm used to. Very nice.

[luvssnow_spokane]

Well I stand corrected    GO King Euro!

I have been staring out the window for about 20 min straight watching it fall...so nice! Easterly wind blowing it up against my slider and I am at 30F!

[SilverFallsAndrew]

Well that escalated quickly...

Yeah I would say so. Thanks for posting the map! So can we officially say that today/tonight is the warning shot so we can get that out of the way?

[epiceast]

Are they going to upgrade Olympia to a warning or not? Seems like it's waaay past due.

[seattleweatherguy]

30 with a dp of 26 the dps are rising fast

[Heavy Snow]

The 00z EURO gives Tacoma North a monster snowstorm Thu/Fri. Big time model disagreement as to where the L will go. GEM and GFS send it into Cailfornia, EURO sends it way up North. Big spread LOL. Somebody is going to get clobbered next week. Good thing is that Arctic air will not be going away anytime soon.

Still snowing there?

[VancouverIslandSouth]

Just started snowing here in Victoria. It's coming down pretty quickly, though I'm not sure how much longer this band will last. The GFS seems to keep the outflow going until tomorrow evening with 925mb temps below freezing until well into tomorrow night. Low level temperatures are shown to warm, but I'd be happy if it just stayed as snow until early tomorrow afternoon.

well post the map son

[Randyc321]

At about two here.  Sitting at 30.5.

That band of moisture sure seems to be headed straight up the peninsula.

Its snowing decently right now without any radar returns overhead

[Heavy Snow]

well post the map son

I would but we're not really suppose to post WeatherBell EURO maps. I logged off there but I think it showed around a foot of snow for Puget Sound.

Donald trump would.
