TheCloser24 Posted November 27, 2018 Share Posted November 27, 2018 12z FV3 GFS shows how next weeks storm COULD be wintry. Link to comment Share on other sites More sharing options...
CoastalWx Posted November 27, 2018 Share Posted November 27, 2018 Beware those mjo diagrams. They can be contaminated and show the mjo going into phases not true. You’re better off looking at the VP (velocity potential) at 200mb. This is basically showing where we have divergence and where the mjo will typicaly show itself. The EC is usually best for that. However if you use those Wheeler diagrams, look at the EC. I believe the gfs still has a retrograde bias. Link to comment Share on other sites More sharing options...

The other models...heh, off and on more or less. The FV3' isn't shy about cold boundary layer systems over this pattern (thus far that I've noticed). Not sure how it is scoring. The model's 'experimental' technically, but is scheduled for parallel roll-out in mid December. That'll be interesting! Get to start making 'official' 'er comparatives.

Certainly a different look than the GFS. Just from casual observation it seems as if the FV3 tends to be colder than the gfs. Link to comment Share on other sites More sharing options...

Though that wouldn't explain why the FV3 is colder from a hemispheric pattern perspective. But I have noted that the FV3 is def doing a better job with the BL cold in storm systems.

Typhoon Tip Posted November 27, 2018 Share Posted November 27, 2018 In any case... the current perf monitoring on the FV3' discusses that it does have a progressive bias in the middle range ... to which next week is bit late on that but within reasonable scope. The 00z Euro was primaried up over the eastern Lakes with another one of these excruciatingly boring pallid commitments to secondary... So, it might be interesting to 'contest' the two, and see if the FV3 goes back west or the Euro comes east...etc...etc Link to comment Share on other sites More sharing options...

Like, 'too fast' or 'too far east' are both encapsulated in progressive bias; but they have different causes.. They're likely subjective (physically influencing...) one another, but, looking at snap shots of D8's and 5's and 3's ... a system being corrected gradually west could be slowing down across successive model runs as much as the model being too stretched in the west-east coordinate. blah blah ..

EPS at 0z had the worst of it a bit NW. significance? It depends how far north. You don't want it sitting over N AK and the Beaufort sea either. If it starts getting more toward Siberia like over the Chukchi and East Siberian sea then that can be fine...or far enough west where it crosses the dateline and allows for some ridging to pop in western Canada. We could also mute the impact if we either get a really good split flow coming onshore in the west (this will reduce the Canada torch if a chunk of the mild air is diverted to the southern stream by split flow) or we can somehow get a -NAO. The latter seems tougher to get and models aren't that excited about it...though a couple runs have hinted. Regardless, none of these are going to stop the milder pattern...it's probably coming unless really big changes happen fast...but it could be a less hostile mild pattern if that occurred.

ORH_wxman Posted November 27, 2018 Share Posted November 27, 2018 Hope the OP euro has the right idea in clown range. It pinches off the EPO ridge into a block N of AK. That would create a lot more resistance for the one eyed pig's destination. Link to comment Share on other sites More sharing options...

This contains some useful info - ...also, discusses that it will be in parallel with the GFS in mid December ... which technically right now it is not. The entire doc this comes from is posted by NOAA ... it's over the 9.7+ mb file size so I can't post it here. Link to comment Share on other sites More sharing options...

If an actual EPO block can form as opposed to a ridge, then we will likely see the solutions become significantly colder. And yes, frequently a ridge of that magnitude does seem to pinch off a block. Obviously the strength of that block is important but even a weak one is still a lot more resistance than a transient ridge. Link to comment Share on other sites More sharing options...
USCAPEWEATHERAF Posted November 27, 2018 Share Posted November 27, 2018 I like the 5-10th period for a storm on the East Coast, models seem to be in a -NAO pattern with 50/50 low blocking the pattern allowing it slow down some, this would be perfect as a decent cold air mass is modeled over the region before the 10th of DEC, this should allow a coastal storm to bring in snowfall to the coastline for a change, instead of this constant rain barrage. Although short in time and duration, the cold will only last until the 10th and then a torch like pattern ensues as a major ridge settles over the Eastern US.

WinterWolf Posted November 27, 2018 Share Posted November 27, 2018 Wait....so perhaps, just maybe we can salvage a little bit of winter, as opposed to it being over even before it starts, like SnoSki and a few others were thinking this morning?

USCAPEWEATHERAF Posted November 27, 2018 Share Posted November 27, 2018 Latest CPC ensemble guidance for the AO index shows a prolonged negative pattern, which means cold air masses will be around and energy to spark a coastal storm will be dependent upon the location of the Polar Vortex in Canada, if it is near Hudson Bay, Canada and especially James Bay, then the coast seems likely, if it is western Hudson Bay, then cutters will be the storm track. 12z EURO shifts the PV to the east, allowing for a trough over the eastern US and coastal low to develop in the pattern.
