snow_wizard Posted December 26, 2020 Report Share Posted December 26, 2020 1 hour ago, Phil said: It can, and often does. However, the exact time of year and in-situ tropical low pass regime often matters just as much, sometimes more. Once the event gets closer, it’s easier to extrapolate some of the elements. But the SSW itself can also reshuffle the low pass tropical forcing, ignite the MJO, etc. IIRC, in 1987/88, a SSW torpedoed El Niño in its tracks by setting off one of the stronger MJO events of the decade into destructive interference at a vulnerable point in the OKW cycle. I’m not 100% sure if that’s the correct year but that is the sum of it. I do know that we had a really close call with something epic in early Feb 1988. As it is it got cold here with a little bit of snow in late Jan / early Feb. Rare for a Nino. Quote Death To Warm Anomalies!

snow_wizard Posted December 26, 2020 Report Share Posted December 26, 2020 1 hour ago, Phil said: ECMWF vs GFS D10. Notice how GFS wants to finish with a much stronger Eurasian daughter vortex vs the ECMWF...which is both more aggressive with the event and sooner to split it vs GFS. How exactly that unfolds could, in theory, make a difference. One of the many “dominoes” @Brian_in_Leavenworth mentioned. This is going to be a fun learning experience for all of us. It's pretty easy to see this is going to have an impact on the remainder of this winter. 4 Quote Death To Warm Anomalies!

Jesse Posted December 26, 2020 Report Share Posted December 26, 2020 Raw and chilly Christmas, 39/34 spread here with close to 1/2” of rain. Snow was close to mixing in at points during the onset of precip. Currently light rain and 38. ESE winds are still hanging on for now although I see many spots have switched to southerlies this evening.

Gradient Keeper Posted December 26, 2020 Report Share Posted December 26, 2020 6z GFS .... Through Day 13. It could be nothing, but after Day 6 Day this run does not have a Greenland block with the positive anomaly displaced further south over Maine, Newfoundland, the Labrador Sea, and North Atlantic. This is the first GFS Op run in many days that did not feature persistent ridging/blocking over NE Canada and Greenland. Am I just grasping at straws?

I remember it vividly in Happy Valley, started out as some sprinkles then got heavier and turned into a nice coating if ice mainly on cars and sidewalks, then a very quick hitting line of all snow rolled through after dark, snowed gangbusters for a good hour or two, then that was it. I believe it got into the mid 40s Christmas day. 1 Quote Link to comment Share on other sites More sharing options...

This illustrates a significant sudden stratospheric warming event will be at hand. Still waiting to see if the Stratospheric Polar Vortex splits or not, but there's a good chance here. Judah Cohen @judah47 Dec 25 Not sure I can ever recall a pattern like this across the Northern Hemisphere - all wave one (almost looks like +AO but with the polar low over Bering Sea). Should bang on the #polarvortex pretty good; cold, stormy with mountain #snow in western N America & mild in the East. Judah Cohen @judah47 21h Some impressive WAFz (poleward heat transport in the atmosphere that perturbs the #polarvortex) predicted by GFS over the next two weeks. As I have been writing in the blog, it is my observation that when the WAFz is that strong it is mild in the Eastern US. 3 1 Quote Link to comment Share on other sites More sharing options...

That’s depressing and makes it seem more likely that we will go longer than a century here before another one. No, Portland had white Christmases in 1937, 1924, 1921, and 1909. Just wasn't measured at PDX since it didn't exist yet 1 1 Quote Link to comment Share on other sites More sharing options...

Yup. We had 5 inchesl yesterday afternoon and evening. This snow will stick around, as the polar jet will eventually head our way and give a lot more snow to our area. Last year it seems we got the southern jet and the systems were warm. So it won't be bitter cold, but seasonal temps will give us lots of snow. 4 1 Quote Link to comment Share on other sites More sharing options...
