Amazing how the Central and South valley is going to score big time again. Euro looks almost exactly like the GEM.

All reason to believe it will last thru the weekend. - i84 thru the gorge will be down for days.

Is there consensus on when the snow would change to freezing rain in Portland?

This may all change at the last minute, but lets all take a moment to bow to the wisdom of the GEM for going with the southern solution days ago.

Severe flurries in sw portland

Not unreasonable to see how a low could kick off about 50/140 and move inland like last nights gfs showed.

GEM was the superior model in the December event.

Whoa, thats a recipe for a big snowstorm.

GFS has shown strong hints of this for several days now.

Could be jackpot for Portland.

Shhh, don't be negative.

The 850s are quickly warming before the moisture gets here, and models keep delaying the precip. Could be a losing race.

Is that low a bit further south too? Start of a trend?

This looks like 2004.

amount of moisture progged to head inland after the arctic blast is astounding.

Now I'm convinced.

California can start to back off the drought predictions.

Wow, -20 850s encroaching into eastern Oregon by Thursday afternoon.

-10 850s to Portland Friday morning will be plenty cold.

Average about -10 in long range?

Blocking stays nearby in the 12z - not a fan.

Serious precip with 850s under 0 - mountains could be in catch-up mode next weekend.

Ridge is just way too close to the coast again. Rinse, repeat.

We may not get arctic air in the mid or long range, but the near certainty of a good soaking next Tuesday and Wednesday for Oregon and northern California is pretty exciting.. 12z gfs confirms. The Euro and GFS have a similar ridge positioned in the pacific, but it's so dirty that it will be tough to get a true arctic blast.. Canadian on the other hand, is just getting ready to reset to the same weather pattern that we're used to.

So what's the difference between the kontroll and hauptlauf
