Timmy Posted December 27, 2014 Report Share Posted December 27, 2014 Well there goes our snow covered basin and gorge I haven't seen any meaningful snow in any models for the basin. At least the majority of the lower areas. People need to realize that Spokane is not in the basin. Not talking about you. Quote Link to comment Share on other sites More sharing options...

Phil Posted December 27, 2014 Report Share Posted December 27, 2014 I'm not doing that. Rereading you post, nearly every event hinged on the availability of a warning event to break down the PV. You went into great detail on that. This entire season I have been of the mind that this was the basis for your forecast, and TheNewBigMack was able to support that with his incredible depth of knowledge of MJO phasing. The strat response is already underway..I don't understand your point. The PV split is going to happen..The catalysts of which will determine the level of upstream wave synchronization. This is irrelevant to the discussion: http://catchmypicture.com/f/erZuN8/640.jpg http://catchmypicture.com/f/esvXdr/640.jpg http://catchmypicture.com/f/ajYpTk/640.jpg Jared is lying about how I laid out the cause-effect relationship between the tropical forcing, strat feedback, and the mid-latitude circulations. I did not forecast a drop in the NAM to precede the NPAC/NATL breakers..that's impossible. I did not say the wave-2 strat response would force the PNA retrograde..I said the caralysts behind the strat-response would force a duel breaker regimen, followed by a strong NAM drop, while the tropical forcings favored a PNA retrograde.

Highly plausible since this only goes out to hour 192. Thursday overnight looks snowy into Friday. No great westerly or southerly flow as moisture arrives. Lots of low level cold still left. Then reload arrives, we could be cold throughout this duration. Quote Link to comment Share on other sites More sharing options...

luvssnow_spokane Posted December 27, 2014 Report Share Posted December 27, 2014 Day 7 GEM ensemble mean is excellent. With this upcoming pattern, the main thing we don't want to see is the -EPO block float too far north into the Arctic...then the block gets undercut. Of course, if everything came together right that could mean a nice overrunning event, but it would also mean the cold spell gets shortened. GEMens.pngPrefer cold longer than an overrunning slopfest.

bainbridgekid Posted December 27, 2014 Report Share Posted December 27, 2014 There is snow on the trees so my guess is that its accumulating on surfaces other than the interstate. I heard snow levels will be dropping too. Oh definitely. It's been exactly 32 at the pass all day so no doubt it's piling up. But I might be going snowshoeing up there tomorrow and am hoping to be walking through snow that does not soak through my clothes in ten minutes. Should be a drier layer on top as snow levels fall later this evening.

If someone perhaps knowing more about what I have than I do maybe, questions whatever, I do the same. All for the good.I would agree. I think what is at stake here is that there are people on this great board that have a wide range of knowledge or levels of understanding. Sometimes the more "educated" or more "knowledgeable" become impatient with those of lesser degrees of "experiences". Some do a great job with it, some don't. Also, what is at stake here are how things are delivered. I've been an educator (science/biology) for close to 40 years and delivery is everything. Learning how to speak is golden. Learning how to deliver a point, defend something, or teach something or as you said, "help them see better", is an art. Teach one another how to learn. Otherwise it becomes criticism of the wrong kind, bullying, intimidation, attempts to embarrass, etc, etc. Over all people do a good job here but when the models light up and we get our few good chances per winter to score cold and snow, something happens. Sorta like the N. Korean's when they don't like our movies. Quote Link to comment Share on other sites More sharing options...

Snow Posted December 27, 2014 Report Share Posted December 27, 2014 The new 12z GFS looks spectacular for a huge snow/ice storm for the PNW. Take a look at the analog composites.

If PDX pulls off a coldest day of 32/24 and SEA is like 36/24, that's really not much of an event for this time of year.
