The euro ensembles did show some troughing into AK and Bering Straits, but also tried to pump up ridging into Greenland. These could be features where models build up ridging in some spot and then 12 hrs later break it down and build it up somewhere else.

 

Also the GEFS continue to look decent post day 10. Nice -NAO. Whether it is right, who knows. Of concern is the MJO and the fact that is doesn't really support those looks..but MJO isn't everything and the forecasts in general have been too bullish with the amplitude.

I think it generally argues for a slightly slower progression.  You can see even the -AO/AK ridging/-EPO the center of the country isn't super cold.  later January could be really fun if the MJO continues in Phase 7 and Phase 8.

 

Plains/midwest snowstorms at first...then NNE...then slowing slipping to the coast?

how so?  are you just talking about the well-advertised above normal pattern or what happens after?  It averages colder than normal over the east post-216 hours.

 

Yup.  For AUG it looks like post-216 thru 384 it's about -5 for temp with 1.5" qpf.  Unfortunately, it also has about 90% of that precip as rain.  Same as it has for this coming Wednesday night.  However, as others have posted above, it's good to see the pattern get active, and we'll wait and see where the storms go.  With this much cold air around, they can't all be warm...

The MJO has been pretty much a non-player thus far. Not only have the amplitude forecasts been too amped, we've also seen some faux signals. Some feature "forces" the MJO into a certain phase when the "true" MJO isn't really there.

 

It will be interesting to see how this particular forecast MJO ends up looking both on the charts and how it affects our sensible wx.

Yeah, it really hasn't done much thanks to the amplitude being relatively flat. But, just nothing what the progs have..we'll see if they indeed get a little amplitude or stay flat.
