Portland escaped the torch yesterday with a 43/33 day. Right now it's 42.

[TT-SEA]

Looks icy in Leavenworth now.    Its crazy how well the Columbia basin in WA holds onto cold.    Its still 29 even in the Tri-Cities despite the massive torch happening over here and at the upper levels across the PNW.

51/47 yesterday with 0.35” of rain. Spiked to 58 earlier this morning 56 now with another 0.28” since midnight. Amazing how wet and mild it’s been the last couple days after going into the freezer big time.

61, actually!

And note when the warmest temperatures were: when the downsloping was the strongest. This is vintage Bellingham. In the two winters I lived there, both featured 60+ readings that were not shared by most other stations unless you got hundreds of miles further south. It got to where I was able to predict when these spikes would happen, based on wind forecasts.

It’s quite localized. Did not get warmer than 52.2˚F last night here.

[MR.SNOWMIZER]

Winter still locked in here .

Cle elum.

[TacomaWx]

Looking at precip through the end of the month…this could be our first above average precipitation month since June. Mountain snows should return soon as well. The last couple days will take a bite out of our big negative departure this month but overall still a very solidly winter month here. 

[MR.SNOWMIZER]

Looks like we will torch at cabin for about 24 hrs then temps will crash back down. Torch up there is mid 30's. Wednesday through Monday will be 25 -30 during day and 20 at night. Perfect for outdoor activities. 

[Ellsworb]

A balmy 55 and rain on the east shore of lake tapps. Quite a run from only a week ago!

[MR.SNOWMIZER]

Freezing rain here on blewet pass

[ShawniganLake]

South winds broke through here. Temp up to 51 and the power is out. 

[Roman-Dallas Snow-Zone]

I wonder if NWS will issue High Wind watch for Willamette Valley soon? 

[antipex]

30 here with freezing rain.

[awright-31]

57/45 yesterday.  

Ended up losing power last night due to burglary/vandalism on a PSE power substation on Kapowsin Hwy. There were 4 substations attacked in total.

[Hour364Please]

58 and HEAVY RAIN in the Puyallup Valley

balmy outside

wow!

[MossMan]

Feels and sounds like we are approaching windstorm status right now up here! The sleds went flying off the deck! Power flickering here. 

[SnowySeeker50]

Woke up from the heavy rain. currently 52 degrees

[TT-SEA]

SEA had gusts to 55 mph in the last 20 minutes.

Still very little wind here... maybe it will come after the front.

[TT-SEA]

.67 at SEA today so far... approaching a wetter than normal month and getting close to normal for the water year.    

Quickly making up lost ground after the drier/colder than normal period for the last 7 weeks.

[umadbro]

Finally mixed out at some point overnight. 51 now. It was 37 12 hours ago.

[Phishy Wx]

up to 34, with rain. but the ground and driveway are so cold and frozen looks like rain is still freezing on contact

[Prairiedog]

Main energy looks well north of PDX.  Front just approaching the Portland area soon.  Looks like an average run of the mill.  Only .1" since midnight here.  Calm as can be out. 47f, 

More interested in the next front and how much wind we get.  For once we didn't lose any power as the ice was minimal over all.  Not sure what we'll get wind-wise here yet with the next front.  Iso's look pretty packed and they're aligned right.  Just have to see what the pressure ends up and how the low ends up tracking.  Right now it looks to stay just far enough west for damaging winds but wouldn't take much of a shift. 

[Phishy Wx]

everything at ground level and the snowpack are ice encased.  wonder how much snowpack we lose the next 2 days in the 40s, not think much unless it really torches with SW wind

That is where we were at 48 hours ago.    Still have not had much of a SW wind here but that ice on top of the snow cover does not last when its in the 40s.  It all turns soft which progressively speeds up the melting.    But as long as you avoid a strong SW wind then the snow cover will probably remain intact.    How much do you have on the ground right now?

15-16" ish and probably an 1" of of solid ice on top

Wow... that is twice as much as our peak in the last week.    Safe to say that snow cover will be around for quite some time.  

[....]

We hit 60.6° around 3am. 🫥 We also lost power for a bit last night, due to the sub-stations being vandalized. Hubby is in the thick of it, works for TPU and had his guys out all night trying to fix their subs that got vandalized. Both PSE and TPU have had stations hit since Christmas Eve. I hope the f*ucks that are out doing this get electrocuted. 

[Doinko]

Most of the Hood River Valley is still in the 29-32 range

[Phishy Wx]

getting puddles now on the ice in the drive.  melt has definitely started

[T-Town]

Some pretty wild wind and rain here earlier. Much calmer now and 51 degrees.

I have a 36" bullet proof snow pack currently but 3-4" of rain is forecast for tomorrow. will be interesting to see what happens here.

That may be true, but I'm 10-15+ miles away from the nearest foothills and in this case I was pretty darn close to BLI's 61F with a high last night of 59.3F (the same as two stations in the city itself). It looks like many stations throughout Skagit and Whatcom were within a degree of 60F so unless we're all exposed to downsloping similarly, I think last night we were just in a warm sector of the storm.

But BLI still got a few degrees warmer than other stations. I still think downsloping was involved.

[MossMan]

One year ago today. 

[SilverFallsAndrew]

Looks like a La Nino pattern to start January.

[MossMan]

PNA is blasting into space. Yuck. Hope it’s short lived. 

[MR.SNOWMIZER]

The ice on top of the snow is crazy here.

The Associated Press - en Español: Western NY death toll rises to 27 from cold, storm chaos.

Well I was hoping I would see more then 2 inches of snow this winter, this ain’t going to help.

February 

[SilverFallsAndrew]

CFS weeklies flip below normal as soon as February starts. 

[antipex]

32.2 now. First time above freezing since the 12th. Four highs in single digits; three lows below zero peaking at -22 on the 22nd. Average temp for December is 20.3 so far. Somewhere between 25-30” of snow on the ground and a layer of ice on top.

[snow_wizard]

It's beginning to look like the models are latching onto a fairly drawn out retrogression scenario going forward.  Big ridge sets up along the East Coast, retrogrades to the West for a while, and then ends up over the GOA late this next month.  With some coolish weather early in the month, maybe some fake cold mid month, and then real cold late month we could still pull out a chilly January.

Obviously this whole idea could change in a day though.

It kind of looks like it could start late Jan on a few runs.  Some of the best events on record are late Jan / early Feb events.

No doubt this will go down as one of the great Nov / Dec combos on record for cold.  Especially east of the Cascades and in the NW Interior of WA.

[snow_wizard]

I think the big wildcard that could speed up our road to cold would be an unexpectedly potent MJO wave.  Would love to see January deliver this winter or at least not be a total turd.

[Skagit Weather]

Cali is looking just a bit wet on the major models. Up to 30" of precipitation in the Sierra on the GEM and 15-20" on the GFS/Euro over the next 10 days.

No doubt the switch has flipped for them this winter.

[snow_wizard]

Looks like we had a pretty weird blast of wind here earlier today.  Dead calm when I went to bed last night, dead calm when I woke up, and yet my weather station says there was a gust to 32 at some point out of the SW.
