Sigh 18z EPS/Control are worse...

Really going to need to hope these temps are way too high 

What does the control look like for temps on Thursday and Friday?

[jcmcgaffey]

It does look like the sounds is now starting to fill in but I think it might just be for a brief period as this last batch of moisture is coming through then seems like it would lighten up. 

[Jbolin]

Folks, I know what the issue is. See, I haven't played RCT3 in like 10 years and that's why it hasn't snowed with any significance in the central sound.

I'm booting up my Colecovision as I type this and accumulation should commence sometime after 11 p.m.

[snow_wizard]

Snowing and sticking here.  Ground is already white!

Its already dropped down to -6F here at my house this evening. This before the real Arctic air moves in here on Wednesday which is crazy when you think about it!

Windchill Warning and Winter Storm Watch have been issued for windchill values as low as -60F/C and 4-8" of snowfall on Wednesday. Going to be a heck of a brutal 48 hour stretch!

You guys are going to get smashed.  Our best winters are usually ones that are very Montana centric.

Started out as sleet actually here, but it's all snow now and the temp keeps tanking.

I thought the GFS was crazy with CAA, but the Euro now wants us to get down to 12 degrees? Wow

What's the coldest temp you've seen there to date?

Coldest at my house has been -25F (set last Feb). We sit in the foothills a little bit so we don't decouple very well but we still seem to do pretty well.

We have a very hefty snowpack this year already (~30" on the ground currently) so I'm thinking we get below -30F with this and the airport pushes -40F. February 1996 was the last time that the airport was as low as -40.

[thisisacreativename]

Huge flakes now.

[WildrootParable]

It is hilarious and annoying to be right in the Central Sound Circle of Shame at the moment, but at the same time I'm glad for other people who are seeing the fluffy stuff, especially my north Kitsap brethren. Since we lucked out so well in the last one, it only seems fair. 

That said..........it would be nice to get just a little bit to make everything pretty in the morning. 

[MWG]

Grats for those getting snow! Low was 18F and a high of 43F. Currently 35F and not much going on for this week.

[MossMan]

Down to 25.9

You should easily come in -30 to -40 from what I'm seeing.

[lowlandsnow]

HRRR is a lot colder than the ECMWF

High temp tomorrow

Its the control run... not the ECMWF.

That is crazy, that is about my all time low at my cabin in north east Washington.  Been to 20 below probably 8 times but 25 26 below only a few times.

No one posted the temps for hour 90 of the euro?

Yeah, this looks like it should deliver the coldest temps in a long time for many places in ID/MT/WY/CO. Euro showed your area reaching at least -35.

Some place in western MT will probably hit -50 with this.

[SilverFallsAndrew]

8/-15 at Burns today. The -15 broke the record of -9 from 2012.

It still appears the ECMWF is a notch too weak with the CAA.  Hopefully that's the theme for the next couple of days.

I sure hope the Arctic air makes it to Eugene.

[lowlandsnow]

The HRRR is farther south than the ECMWF with Tuesday's system

Incredible when you consider that the real cold isn't even here yet.  We are on an insane roll right now.

[Meatyorologist]

Lytton down to 3F.

Is it south of its previous run?

This may be the coldest they get. Incredible how good the Harney Basin is at getting cold with deep snow cover and a stable airmass. What they are seeing now is an inversion. There are stations above the basin floor that have had highs around 30 the last few days.

Euro says it does. Big question is whether they can score a sub freezing high. May come down to timing.

Don't know can't see the 18z on weatherbell. Only the 00, 6, 12, 18 go out to 48 hours.

 

[jakerepp]

Looks like maybe we bottom at between 5-9 here where I am this week. My parents house is out the country roads away from the more urban areas so it will probably end up a bit cooler here.

You are just inside the colder portion of the airmass hovering north of us.  I'm at 32F and that is a bit warmer than I was a couple hours ago.  There seems to be almost no southerly movement now with the colder air.  It will be interesting to see how our low temps bottom out.  I'd like to have some bit of snow around for Christmas but that is starting to look challenging.
