WAR keeps expanding W and subsequently blocking the PV farther W on the gfs

The WAR isn’t a cause it’s an effect.  Or at most it’s an interrelated piece of the long wave puzzle. The war isn’t causing this to happen. The war is happening because the forcing in the pacific is not favorable to propagate the epo pna ridge eastward into the conus for us.  For some reason guidance keeps totally Fng that up at range only to adjust west every time. And so we see each threat adjust west as the whole ridge trough axis shifts west.  The causality is the ridge in the pacific is centered off the west coast.  That is due to unfavorable forcing near the Maritime Continent. We need the forcing east of there into the western and central pac to drive that ridge into the western US. and that will force the trough into the east and push the war east. You’re right the war there is a problem but you’re looking at the causality backwards.

Hybrid then? It pops a low off the jersey coast before slamming it into interior north east. 

If you look at the MSLP panels it shows an area of elongated LP overhead and to the south of us. As the trough goes negative the LP gains strength to our north. It's all one cohesive (and complicated) piece rotating around. CMC is relatively similar to what the Euro is doing.

GFS and GGEM both have some upper-level induced snow in the OH Valley next Wednesday that looks like it tries to create a weak surface low in VA as it moves east.  GFS throws out a few snow showers with it, GGEM keeps all the moisture west of the Apps.  Another thing worth watching.  That would be very dependent on the precise track and strength of vorticity pieces that are rotating around the PV.

LR looks like Pacific is gonna crash the cold for sure! (GFS) - Not too excited at this point based on that model!

 

It’s been trying to do that often the last week but has continually pushed it back or even lost it for many run cycles on the Op and most ensembles.  The GFS is likely mishandling the MJO which could be a cause for why it’s continually trying to break the pattern down

Looks like most guidance lost the big signal for next weekend now. That decelerated quickly.

For now it's a suppressed/squashed wave. Practically every time there has been suppression since mid Dec in the mid range it has backed off as leads shorten. Might be a good thing that guidance is showing a squash job down the line. Much will hinge on the TPV progression which is anything but figured out.

Gefs stills has some interest in the Day 7 deal.  Some very nice solutions in the mix.

might have to get the blue bowling ball here first before we know what next weekend will look like.  as-is, trough looks too far east and has a miller B look, but i could also see where that could trend better as we go, at least for the eastern sections.

Definitely.  It basically shows shotgun solutions and will all depend on timing.  Which we are so good at lol
