Interesting turn of events as the EURO actually ejects the piece of energy out SW and pulls it into the low that forms in 100 hours or so … still things are way too warm for anything to happen but that’s the first of that look I’ve seen on models. We would need a much more wound up system for anything fun to happen

This actually looks plenty cold enough to me to yield a rain/snow mix in parts of the eastern NC. If the wave amps more + yields more cold advection on the NW side and legit precip falls back into the trailing air mass, the 850s will drop even further than shown here as will surface temps.

Here’s the problem with the MJO prospects. Three days ago, the Euro had this forecast, which I called “yummy”:

The Euro forecast has since taken a sucktastic turn for the worst and now has this “I can’t get away from the MC” scenario (due to very warm MC I assume) that isn’t “yummy” at all:

I’m trying to remember if this area is where the Euro is not so good and that the GEFS might be better. @Webberweather53 and I have discussed this before.

There are many things the Euro is not so good...the MJO being one of them.

I don’t think it is that simple. Depending on where the current MJO is, the Euro is better in a good number of scenarios and the GEFS is better in other scenarios. @Webberweather53 knows all about this and it may very well be the case that the Euro isn’t progressive enough when the MJO is in the MC like it is now.

Sounds good. I confess I haven't done extensive research on which background states the ECMWF is, by a small statistical significance, too progressive or conservative for all of the various indexes, convective systems, tropical forcing mechanisms, stratospheric propagations, or H5 progressions. However, I have seen it, like the GFS, GEFS, CMC, and its own ensemble suite, frequently reverse on all of those things, especially beyond D5 or so.

Webber might be able to tell you that it has a 51% chance of being too progressive in a 2nd year La Nina, but Rain Cold can tell you that the European model is a hunk of junk at the end of its range.

Well, a little good news for cold lovers is that the HappyHour GEFS doesn’t have as strong/long of a torch following the current cold and when it subsequently cools back to at least normal.
Some of the GEFS really getting excited about a period of possible severe weather along with a significant cold snap back to reality after with plenty of mischief in the middle .. first group of much more exciting ensemble members I have seen in a little while

This may be a Webber question. In all seriousness, do we want to see the mjo fire up and get into phase 7 to have any real chance at a colder pattern later? We dont want to be chasing unicorns all winter lol. I'm just trying to put 2 and 2 together. Also I think if we get a flat aleutian ridge instead of a poleward, that wont be good either. The niña, imo, looks more east based with coldest anomalies in 1+2 region. And -qbo.

On a brighter note, the GEFS, which tends to do somewhat better than the Euro when the MJO is in the MC because it is correctly more progressive, is encouraging for potential cold mid to late Dec. Who needs the over-rated King anyway? He’s just a figurehead.

It doesn’t matter if you had the MJO in phase 2, a +PNA that reached all the way to Australia, a -NAO that was the strongest ever seen and covered all of Canada, it would still 33 and rain! It’s just the way it is now! I’m glad I was there to witness January 88!!! Still the greatest snowstorm of my lifetime and I don’t think it will be beaten up here either!
