Umm... YES PLEASE!!!

This includes 6 inches that falls in just 3 hours.

Heavy. I've only been in 2"/hr rates maybe twice at my place.

[SilverFallsAndrew]

That was a very cold run for the upper Midwest. 

[Timmy Supercell]

Somebody got blasted... Imagine 30" in a day. We can barely do that over the course of a few weeks in these parts.

 

[SilverFallsAndrew]

GEM is NOT ON BOARD.

[SilverFallsAndrew]

ICON IS NOT ON BOARD. 

[TacomaWaWx]

Not to throw cold water on the possible snow event but just remember we’re talking about the gfs here. I’d be more inclined to believe it if it weren’t on its own. Definitely has a cold bias.

Someone on Reddit from Binghamton has claimed to have 40''.

This would perk my opinion of 2020 real quick.  At least finally something to drool over.

Like DJ says- Cmon

There were multiple reports of 40”+ in that area.

Officially 44” in Newark Valley, NY and Ludlow, VT.

And 30” of that fell in just 5hrs. Ridiculous.

Annnnnnnd just like that the models just flipped. Holy shites! I’m in the dark purple to dark pink. Please be true

Still colder than the "unofficial" 334F in Huntsville, AL last week during their cold snap.

Watch Port Angeles get another 2 feet of snow in the next event.

They have been on a roll lately.

Wouldn't surprise me one bit considering how the initial low tracks just south of KSEA and N/NW'ly flow on the backside giving some decent upslope flow to Sequim, Port Angeles westward. 

I have some family that lives near Blue mountain, if the GFS is correct, I'm going up there over the weekend in anticipation. 

(Would be my first time "outside" since testing positive for COVID)

How’s the ‘rona treating you these days?

Our county has been going through a "spike" but so far this family has been testing negative thankfully. Still there's been bugs passing around and it goes right to my stomach usually. 

Try as much as you can to get outdoors, it helps to make me stronger. I'm just hoping that next time something noteworthy happens snow wise, that I'm not stuck inside a bathroom for several hours nauseous. lol Off and on since before Thanksgiving I've been doing that every 7-10 days or so.

Good thing the 12z Euro agrees, to a certain extent! 

Perhaps not quite as much snow as the GFS but nice to see them both showing something for that timeframe.

Now I’m more inclined to believe it now that the gfs isn’t on its own. It’s still pretty borderline though. I won’t be here either way if it does send some pics!

[bainbridgekid]

Monday's storm system is certainly very interesting and bares watching, but experience tells us those situations are EXTREMELY difficult to thread the needle on. Especially during the day. We would rely on the exact right track for the storm and very heavy precip to get us down to about 34 degrees to see sticking snow. 9 times out of ten that situation doesn't quite workout.

[Deweydog]

Definitely starting to emerge as another little litmus test for the “improved” GFS as it starts to again separate itself from the pack at a familiar range...

[Requiem]

Very borderline situation shown but it’s really cool that we at last have something wintry to track! Fingers crossed— weekend looks active.

I’m back to the 1st shade of grey. GO GFS!

I am a bit shocked actually, over the least 30 hours I have improved dramatically. The most severe symptoms have waned considerably, I am still a bit weak but overall I feel great compared to 9 days ago. 

The main issue I'm "dealing" with is the lethargy and constant fatigue, I am so tired and want nothing more than to sleep but in lieu of the other major symptoms I had been dealing with, this pales in comparison. 

My Dr. has given me three different inhalers to help with the issues related to my asthma and the associated COVID related complications but according to him, I have the worst of it behind me but a long road to full recovery. My Dr. also indicated to me that my COVID exposure "may" push me into a more severe category of asthma but only time will tell. 

Other than that I find myself to be very lucky considering how bad it has been for others, I do not wish this type of illness, and pain on anyone. 

I am thankful to be on the "mend" and hope that I have no long lasting effects as a result. 

Stay safe guys, please.

I’m confused by some of the comments in here. The Euro was actually the first model to show any kind of potential next week. The GFS was never completely on its own.

 

But yes, as I said earlier this is as borderline as it gets and small changes could destroy low level snow very quickly. 

[MossMan]

Also remember like Brian in Leavenworth keeps saying...It doesn’t take a massive arctic event to get clobbered with snow...Especially this time of the year!

12z Euro details for Monday between 1-7PM for Puget Sound...

Surface temps: mid/upper 30s

925mb temps: -1c

850mb temps: -2/-5c

Euro does show fairly brisk N winds down the Sound instead of the onshore/southerly winds that the GFS shows, but those are still pretty much the definition of borderline parameters for snow. 

As Bainbridge said, this event would require fairly intense precip to bring about an fairly isothermal column.  Threading the needle...

My mistake I thought the gfs was the only one showing this situation didn’t realize the euro did at some point too.

True, but the GFS is starting to emerge as the alpha once again after a couple days of things pinballing around a bit.  Given its track record last winter it seems like a familiar path in the short/mid range.

This is fun, a few more runs like this and the forums is gonna be popping. Let’s go. 

[TT-SEA]

The standard NWS radar sites are gone as of this morning... I don't like the new interface at all. 

 

[SouthHillFrosty]

I have been posting in the Atlantic forum (aka Phil's forum page). Posted three snow maps before realizing it Anyways, JAYA is not on board with Monday

[SilverFallsAndrew]

Someone mind posting the snowfall map through Monday evening that shows Oregon?

Yeah, much more potent system and overall much further west than the Euro, considering we're less than 5 days out.

[SilverFallsAndrew]

Wow Tim is right, the NWS radar page is total garbage. Seems like whenever they an "update" it is far worse than the previous incarnation. 

[SilverFallsAndrew]

Just now, TT-SEA said:

 

Thanks. Looks like it pretty much takes away all snow below 2000' down here.

Here is a GIF of the possible snow storm for Puget Sound

What was their reason for doing that? Wasn't necessary at all.

[Timmy Supercell]

Sorry but I don't like using google maps to get doppler radar. Think I'll be sticking to University of Washington pages for that. Unless UW has the same plans of getting rid of everything we're used to.
