That windstorm shows up nicely on the 18z GFS next Tuesday/Wednesday. 

Was just about to say no rest for the wicked… we’re gonna be right back to tracking that thing. We’re due for a “big one”. 

[SilverFallsAndrew]

Wow the road cams from central Oregon look gnarly! 

[SouthHillFrosty]

Maybe we can squeeze 1in out of this in the Seattle metro area? Kinda optimistic

Switch to CASAG on RadarScope. That picks up super light stuff in the central sound way better for some reason, and must be what NWS integrates into their combo radar map. 

Changing the tilt on KATX worked too. It's moisture higher up in the atmosphere that isn't making it down to lower elevations where the lower tilt would see it.

I definitely hate the fact there’s an ice storm coming but it’s a very interesting phenomenon still. It’s pretty rare here to get ice storms haven’t had freezing rain in 11 years now…one of our more rare weather events and it’ll be very interesting to track and see how long the cold air holds on.

EUG is a very good station, just a notch below OLM. I have faith.

I was worried SLE was going to somehow hit 30 this afternoon, but it doesn’t look like it. Even if they are warmer than any other mesonet station in town.

Yep, NOWcasts incoming!!!  They already changed us from 80% chance of snow to 100% and they extended our timeframe, now expecting it to snow until 7 AM, 7 AM-1PM freezing rain, rain after.  This bodes well for you guys further north.  Could be stalling and be more of a prolonged event.  This intial push does appear to be elongating west to east as opposed to more of a SW/NE push.

How much snow could we get before changing over to freezing rain/rain. Also will elevation play a major factor or not really?

Cold air layer is much deeper east of the mountains, though.

I'm just talking about the delay of the front.  The longer we can get this pre-frontal moisture without the wind shift, the more frozen precip we will all get.  We want this sucker slow slow slow.

Winds have absolutely ramped up even further-- we usually don't lose these many branches from easterlies

Yep! I just reached my minimum for the day, down to 25.3

[Terreboner]

Flakes just got a lot bigger.  Dynamic!!!

I’m with you. I truly hate all weather besides snow and tree killing heat waves  

I love all weather except for inversions. I love you too.

Looks like our roads up here right now, traction is really good! 

Can confirm (after spending 4 hours in a ditch this morning) that traction is not "really good". To be fair my tires are nearing the end of their life and I think if they weren't almost bald the roads wouldn't be terrible, but definitely still some slipping and sliding even with good tires.

The precip over North Seattle that looked like it was just virga seems to have darkened into green a bit. Anyone seeing anything there, or is it phantom snow?

 

Nothing, ironically the dewpoint has dropped back down to 9 with this supposed band! It's 25.5 and the wind is continued light out of the east. 

[lowlandsnow]

Looks like Bozeman only made it to -24 today, Spokane made it to 3, Mazama -1, Wenatchee 2, and Pullman 3.

[joelgombiner]

It does appear to be stalling, spinning, and stretching as it pushes into the Arctic high

[GHweatherChris]

Light snow reported at Astoria, that's a good sign.

[SilverFallsAndrew]

Light sleet/drizzle mix in south Salem now and 26 on the car thermometer. Waiting in line at the gas station hoping I can get the fuckkk outta here before shittt hits the fan!

It almost looks like a secondary low is forming off the coast of N. California.  Maybe I'm just wishcasting.

For sure... it appears the 850mb temp is above freezing there.

Let the graupel vs. ice pellets debate commence.

[HuskyMaestro]

Went to pick up my dog’s meds and the Safeway next to the vet is completely packed with panic buyers lol. Glad I got my shopping done yesterday. 

[lowlandsnow]

Anyone know the last time it got to -30 in Mazama?

Waves at the crowd of Weather aficionados. My first post. Learned and ghosted you all during the major freezing rain storm two years ago. On Genny power for 11 days.  Back to your question SilverfallsAndrew, I'm in Oregon City, maybe 10-12 miles south of PDX proper depending on how the bird flies. Been complete cloudy skies all day. 23.7 degrees at my house. 

I saw some sunlight peeking through the clouds at one point today. I'm a sleep deprived zombie today so I can't tell you what time that was.

You can actually see this looking at Google Maps traffic. Highway 202 is orange in all the roads of North Bend and suddenly flips to green at the Snoqualmie border. I had thought it was just that NB got more snow but it must be due to what you’re saying.

[FroYoBro]

Basically had a temperature range of 20-22 degrees all during the daylight hours today. Pretty impressive without anything falling from the sky. 
 

Currently at 21 and waiting for the ice god to strike.

Likely sleet. Airports will generally default to reporting it as snow.

Which means today will officially go down as the coldest day on record for the airport with a staggering average temp of -34.5. The high today was also their all-time lowest on record. Unreal.

Have to wait a little longer to see what Bozeman MSU numbers come in at.

Day of the big Christmas Eve easterly windstorm, I believe 

[Perturbed Member]

This looks pretty awesome

Yep, pretty similar events with that one just shifted a little further SW.

So todays -27 was the coldest temp in Mazama in 39 years
