Makes no sense we don't score something good in a phase 7 MJO.

Apart from minor changes to the timing, the EPS remains consistent.

At this point I'd still expect other models to cave to it.

While I could be wrong, I still trust the EPS.
What time frame are you looking at in regards to the eps consistency

The GEM actually finishes off in a decent way.

I admire your enthusiasm Jr, but remember the ensembles have been pretty bad this winter and have had a difficult time in resolving the MJO. These teleconnections are not always perfect and sometimes a dud is a dud. Still, I hope you are right.

No particular frame. Just the overall pattern evolution is fairly similar run to run. But timing has been pushed back a bit. I'm not too worried about that though as long as the blocking and troughing remains stable. I don't expect the exact timing to be nailed down this far in advance.

In any case, the other models have been so back and forth that its really impossible to know whats going to happen at this point. Its model chaos.

Yup and this could very easily bust. But IIRC, we didn't have the EPS on board last time. We were just trusting the GEFS, which failed.

So why would we trust the GEFS again when its the first ensemble suite to collapse? For all we know, it could be wrong again.

I think I figured out why the Fishman can’t look at the models.

MJO pronged for phase 7...but some ensemble runs have been consistent with a phase 8 evolution with is consistent with +PNA +EPO evolution...

Would look similar to this:

It's a crapshoot anyways. Climate change is throwing more wrenches into modeling and it's very tough to navigate.

I thought the models were all in pretty good agreement through day 10 last night. Nothing arctic on the horizon.

True but no run to run consistency.

Yup. It really hinges on what the MJO does. Models are usually poor with handling the MJO so thats probably why we are seeing all the chaos.
