Just wondering, does Weatherbell have the 500mb anomaly map for the EPS?  Only seeing the 850's doesn't tell the whole story.  Need both.

So the general theme for the later part of the EPS is a signal for troughing.  Nothing spectacular, but looks like it could be good for mountain snow.  And of course it is hard to get a real strong signal for anything that far out.

IR Imagery
It may not look like much, but our wave/ low pressure system for Friday is developing now. This is well offshore near 48 N, 148 W. When viewing the loop it is evident there is a circulation center. All eyes on this feature the next 12-18 hours to see how much it does or doesn't develop. It is riding a powerful 170kt jet stream with plenty of cold air feeding into it as well. C'MON!!!!

Had a hard freeze this morning, crunchy white grass and decent fog too.
Low was 10, now about 38.

So far I've only recorded 1/10" of actual snow one day, two days of a trace and wet. Maybe this next storm gives me my first 1-3 inch event.

3-day snowfall here shows 5.0" for my place. We'll see.

@snow_wizardwhat do you have for the winter of 1893-94?

Hey.... I know some historic stuff, too 😉

That was a 2nd year, moderate Nina. Pretty classic progression with a very mild December that flipped to frequently troughy and snowy after early January. Like with many Ninas the peak was at the end of winter with a great arctic airmass and arctic front snow dump February 18-20 (similar event to February 2011). Another good snowstorm earlier in the month. And a lot of border-hugging Fraser river stuff in January.

Also some activity in November. Portland had its earliest snowfall since 1835 (?) on 11/2/1893, and the early season cold even led to this disaster

https://en.wikipedia.org/wiki/Madison_Street_Bridge_disaster

Seattle also had snow in a separate event later in that month, with measurable snow in Seattle in November, December, January, February, and March.

The snowmelt from the big Nina ski season in 1894 also led to the worst spring flooding in the region's history.

I remember the AR event last December that was shown to be going into the Portland area for several days then ended up going north into the Seattle area. That was the biggest AR event I can remember with 4” of rain in a little less than 24 hours.

Lol I wasn’t aware of the lack of interesting weather down there! I’ll make sure to not wish/pray for any snow here this winter and to only send my prayers down south.

I remember the AR event last December that was shown to be going into the Portland area for several days then ended up going north into the Seattle area. That was the biggest AR event I can remember with 4” of rain in a little less than 24 hours. 

Yeah, they often end up a little north of forecasted this far out.

Tomorrow's storm? Forget it. Models have long since abandoned it as it's begun to merge with the jet.

The real deal looks to come Tuesday. Look at that f****** storm!!

Huge curveball on the GFS in a time period of relatively huge uncertainty. Even some CAA as that back-end occlusion taps into the weak arctic intrusion in inland BC. Wild stuff; very synoptically interesting. Bears A LOT of watching.

Tomorrow’s storm still looks quite gusty for OR!

Hopefully that one doesn’t Peter out like tomorrow’s storm did. We should know by Monday night.

Elevation 580’ Location a few miles east of I-5 on the Snohomish Co side of the Snohomish/Skagit border. I love snow/cold AND sun/warmth!

At the very least it'll keep us occupied for a few days. Better than the endless bore many of our falls and winters provide.
