ORH_wxman Posted November 26, 2021 Share Posted November 26, 2021 It’s a really active pattern for early December. One of these might cut but I think there will prob be a winter threat in here too. OP run is still folding over the WPO ridge into an EPO block north of AK out in the extended. That is a really good look to keep the frigid air in Canada and into the northern tier of CONUS. Lets hope the EPS shows that happening more. Even last night sort of hinted at it. But with the OP run being pretty insistent maybe it will actually lead the way.

That is another debate.... man, if that whole-scale structure were to cinema over easetern N/A about 400 mi E of present ... that would be a very, very high KU registry - Kinda interesting about that ...D7.5 - 8.5 looks like an ice storm prelude. The D8 even sets up pp that would DEFINITELY result in vicious barrier jet... But then that 55 unit v-max careens in and converts the whole thing into freak show. Actually, that trough has been in the run for 4 cycles ...gradually losing N-S and gaining longitude.. ( W--> E), fyi - 1 Link to comment Share on other sites More sharing options...

If you want to cut it up that way all storms are the same because they all rotate counterclockwise - how about that. Lol Link to comment Share on other sites More sharing options...
CoastalWx Posted November 27, 2021 Share Posted November 27, 2021 There isn’t anything imminent but maybe 12/5 can become something of interest? It’s been slowly getting better from a screaming cutter a couple of days ago. Otherwise, the pattern has been getting better on guidance. I do think we’ll play with fire as the trough sets up near AK and the BC coast. But as pointed out, that ridge near the pole does try to help keep the cold in Canada. After that, it does look like ridging near dateline does develop. I guess you could say anything before 12/12 or so is gravy. I do think we will have a snow chance over the next two weeks. 2 2 1 Link to comment Share on other sites More sharing options...
Typhoon Tip Posted November 27, 2021 Share Posted November 27, 2021 The EPS mean from 00z, days 6 thru 10, argues pretty strongly the Euro is over-correcting with that complete reversal it sold on that run. I am not sure ( cross-guidance consideration ) the GEFs means agrees with that either. The recognizable polar-stereographic layout of 500 mb anomalies ( as well as the overnight telecons that are based upon those numerical values ) offer more 'buckled' PNAP than neutral. Both it, and the EPS mean, have a whopper Date Line positive anomaly, maintained across multi-day continuity mind you. The standard R-wave distribution ( as a plausible corrective forcing ), argues for lowering heights NE of Hawaii, which concomitantly leads to rising heights into western N/A as the mass-loading/telecon suggestion. Short version, less support in its own cluster, or cross guidance. The only reason I'm spending much time with this tedium is because if anything, there's a bit of a storm signal ...particularly D8-10 out there, as both EPS and GEFs mean appearing to be oscillating the hemispheric amplitude into a meridian tendency.. The the flat oscillation is actually D4-7 and the Euro just sort of locks that beyond which doesn't appear supported. 1 Link to comment Share on other sites More sharing options...

Doesn't work out that way ..even 'relatively' That's actually a cold look for us overall, which may or may not be discerned depending on who's looking..heh. But that deep Canadian vortex helps to reservoir cold that gathers mass from D4 right out to D10. Subtle confluence in the flow in the incredible gradient that sets up is going to then displace that cold under the westerlies .. Looking at the the 850s and surface evolution, that is evidently so - uh... that is, relative to this run. Link to comment Share on other sites More sharing options...

I mean I wrote about this above earlier this morning, too - how it is evidenced not just in the 00z EPS, but the GEFs too, how the operational Euro is flat flow happy compared to these other means.
