Late November/Early December disco on the upcoming pattern

Nothing but a gully washer on the GFS. Need the first system to drag the front through, otherwise it's just what we all feared which is with no blocking things go west.

That one of the 5th has looked warm for days now. The question was if any energy could dig on the backside like the euro op had, but that euro can be aggressive with that.

Basically every modeled cold shot is falling apart in the face of the Uber Ridge in the western Atlantic. I mean you know this is extreme when you see this last low close off and give Memphis snow rather than progress into that positive anomaly. So the models are sniffing this out now and the ECMWF answer is to close off the low over the Northeast...because hey it's running into an immovable wall.

It still has a shot particularly the further N&W you go. But after that yick.

This is pattern creep 101. Everything falls apart/gets muted/pushed back.

Only good news on the GFS is each successive storm tracks further west. Eventually they'll hit us from the east at that rate.

:lmao:

I'm going to step back, spend time with family, enjoy my good health and celebrate. The weather will do whatever it does. This hobby is too obsessional.

Well for at least a one week window we have the ability (AK Ridge) to deliver cold air into the CONUS, but things are conspiring to deprive us even of that.

So if it shows more cold dumps in the far long range ...would they even make it here? We have to hope.....

Cold dump in the late panels, but that is clown time anyways.

You guys are freaking insane.. this thread will be hilarious in March after we had a good winter... take a break?

Everyone says that, but then for some reason the same folks are on here on the board and watching the models at 00z like 50 year old drunkard who return to the same bar every night... remember when we said that November is going to be a long month.. well Novembers done and that went by quick..

Everyone relax

Euro may be too powerful aloft owing to it's assimilation schemes over the polar regions.

S/W in question is a high latitude phase prior to entering the lower 48. Stream interaction/identity and subsequent result carries intrinsic element of uncertainty to put it nicely... Significant jet dynamics relayed out of Siberia on that Euro operational version, and most other guidance I've seen more than less indicate similar. Once we introduce that arctic component things get dicey/interesting/potent.

That said .... teleconnectors don't really support a full- latitude anomaly over eastern N/A during the D5-8 time range; which is not to say the teleconnectors can't suddenly change - less likely to do so. More local scale anomaly could also propagate through.

The SE ridge isn't going anywhere as long as the NAO is positive and the +PNAP expression is a west biased ridge position. That would mean any such diving combination of intermediate and arctic stream coupled system is going to shear to some degree, as the balanced geopotential flow is going to scream with velocity - that damps the jet max. Still, that arctic insertion is going to bring a pretty potent cold mid level jolt into the upper OV, and that could just exceed the damping effect - if so, an NJ model low would be a nice compromise here.

Guess what? November is not quite over and December is 1 day longer.

This Gfs run sucks unless you like a inland runner

yeah its terrible. if there is a real storm (not an anafrontal deal), it will be too far west for here also as shown in the pattern shown by the GFS.

maybe ottawa may have a chance. ottawa needs to cool down and get some snow on the ground.

if that doesnt happen, there is no chance for sustained winter to the S and E aside from thread the needles and transient cooldowns, caveat: unless there is a big neg AO.

Sam's snowfalll anomlay map from last night really illustrated that problem nicely.

Lets not be hating on us 50 yr olds...

Maybe if we had this pattern a month front now when the climo says the SE ridge is vanquished a bit more - we would be able to score some decent gradient pattern overunning events at our 42-44 N latitude region. Agree that absent the Neg NAO it's hard to see why the energy would fully bundle and close off like ECM. It may head in that direction to an extent and then find the weakness in eastern Canada and shear out over the immovable SE Ridge.
