(and Iet me guess...that's one of those more random things that can't possibly be seen in a more LR outlook?) And why is it anomalous, per se? (Not fitting with what you'd see in a nino?) That is the mjo. Breaking it down to basics the mjo measures convective waves in the tropical convergence zone from the Indian Ocean into the western and central Pacific. The oceans are by far the most significant contributor to the atmospheric potential energy. And the tropics add more heat to the equation than the mid and high latitudes. So the tropics are the main driver and the tropical Pacific is our driver since that's what's upstream from us. Where convection and subsidence is indicates where heat is being added to the atmosphere and that heat tends to propagate poleward. So tracking those waves we see a correlation to where the longwave ridges and troughs set up in the mid latitudes. One reason a modoki nino is usually good is the warmer waters in the central Pacific tends to promote convection and heat being added to the mid latitudes in a location favorable to get a western North American ridge and a trough in the eastern Conus. The problem with the mjo wave in phases 3-6 is convection in the Indian Ocean and western tropical Pacific promotes a more Nina like Pacific pattern with an enhanced Pacific jet and a trough just off and along the west coast which floods the Conus with warm Pacific air. That wasn't really expected given the SST this year. Speculation why includes the SSWE and lack of SST gradients due to warmth all over to AAM...who knows. As bob said sometimes the weather weathers. This was really simplified but hopefully it helps answer your question. Link to comment Share on other sites More sharing options...

I can extrapolate this panel into a good pattern just a few days down the line with a trough in the east and the tpv somewhere over or south of Hudson Holy nao lol Link to comment Share on other sites More sharing options...

WxUSAF Posted January 1, 2019 Share Posted January 1, 2019 D10 EPS looks not awful to me. Better than GEFS over NA, not quite as robust as GEFS with high latitude blocking. I’ll let the other folks who pay for it tell us how it craps the bed after D10. Link to comment Share on other sites More sharing options...

The fast Pac flow continues on the EPS I would think that would eventually change, and the Pac flow slows down. Sorry, no concensus yet, still too early.

showmethesnow Posted January 1, 2019 Share Posted January 1, 2019 Good News is, we are once again seeing slight improvements with the PAC jet on the EPS and the improvements are being seen inside day 10. Bad News is, at the rate it is improving we will finally get the PAC jet tamed just in time for our Spring deluge of 38 degrees and rain. Link to comment Share on other sites More sharing options...

Better or worse is subjective. Still shows a -pna, +epo, +ao/nao, and ridge in the east. I challenge anyone to spin that into something good. In my eyes it's another disaster of an ens run with zero reason to believe our area has a chance at snow over the next 2 weeks. Link to comment Share on other sites More sharing options...

If you loop the H5 heights between about 324-360, you can see the whole shift occurring. If we got to see a few more panels, you'd prob see a big -EPO develop. Hopefully that is the change occurring for real and won't get pushed back. From NE...hopefully this is it. Link to comment Share on other sites More sharing options...

The improvement on the weeklies started about 36 hours past the end of this run. Look at the 2 same time... 12z EPS weeklies same time if the EPS are still on track another day later we will see the trough out west split and a piece undercut the ridge across the central US while the main trough pulls back in the PAC and a couple days after that an epo ridge pops. The whole thing happens fast. As soon as the trough pulls back the epo ridge goes up. But that is still 36 hours after the end of the EPS. Link to comment Share on other sites More sharing options...

If we can get to a good pattern around the 20th at this point I'll take that as a win. Link to comment Share on other sites More sharing options...

Only thing I see that's better is the trough in GOA is weaker on the 12z run. Have to see if its just noise or if the lower h5 heights continue to shift more over the Aleutians going forward.

But look at the two panels I posted. Today's EPS actually might look slightly better than the weeklies same time. Definitely the same idea. Very similar. But the PAC trough is weaker and heights up top less hostile. But the longwave pattern is the same. No sign yet that it's changed. Not saying it won't. But this run wasn't any indication of it. That's all I'm saying. Link to comment Share on other sites More sharing options...
