EC dumping coldest air further east now.

Dat analog...

Look at that beautiful L pulling the winds through the gorge. Let's have this setup all winter where it slides down the coast like this.

https://weather.us/model-charts/euro/oregon/acc-precipitation-snow-total/20171106-0000z.html Snow for everybody!

That onshore wind can barely keep the valley above freezing!

Wow this is going to be close for the WV

holy cow!

Just bring that Low a little further south about 150 miles and the WV is in business

Unless you're in the Willamette Valley...ugh

Just now getting out of the low clouds between Eugene and Corvallis. Should be pleasant for the Stanford blowout of the Beavers tonight.

Omg so dam close to the WV. Let's keep doing this once every 2 weeks!

Everyone in the PNW will get something this year. I just don't think it'll happen til mid-December

Hopefully not. I would enjoy the first ever blizzard warning for the Willamette Valley.

Clouds starting to creep in here. I doubt the precip makes it this far south.

Glad of this. Don't want to start having PV drops too early. I want it in December/January where it's coldest.

Really hope that moves further south

Man I hope that storm track won't be a consistent one through the fall/winter because that would put Oregon in the warm sector of most of these events. Bummer.

70 In Dallas, OR. Beautiful

Latest EC a bit less bullish on the cold air. Keeps it north of the border for the most part.

Yeah that's the one. Not quite as early as I remember then. As has been said, there is a relatively small sample size for early Nov cold air. I'd rather it hold off til later so Oregon has a better chance for snow though.

I do remember the early snow in November in Eugene in 2003 with a cold rain that eventually lowered the snow level to the valley floor with a heavy enough band. It lasted a couple hours or so. So that analog would be a good one.

I feel like an early blast could be a bad omen for later as well. Like we are blowing our load too early.

Same thing happens in the western Willamette Valley when we are in the icebox and a low pressure system overruns it. The eastern outflow from the Columbia River Gorge toward the low center creates a cold air dam that pushes the column of cold air in the west valley higher, so as to delay or outright prevent freezing rain or sleet developing (such as what happened in 2008). This is why places like Lebanon, Silverton and areas in the east valley have the warm nose affect them sooner with freezing rain/sleet or simply rising above freezing in the lower levels sooner than, say, McMinnville, Grand Ronde, Dallas, Monmouth/Independence, and sometimes even Philomath/Corvallis

Yup. That's why NE Texas experiences a lot of ice storms because that lower level air is indeed colder than aloft as you say.

Hopefully will be the first of many pass-bys of that lovely big Canadian H
