March DISCO/OBS: Please End It


40/70 Benchmark
 Share

Recommended Posts

I don't know if I really like comparing March setups or March potential to like December, January, or even February. The wavelengths really start changing during the first half of the month and we start introducing the hemispheric shift between seasons...lots more chaos involved - which can go good or bad and sometimes the change in wavelengths can mean all the difference.

Yup...just being negative.

I don't blame you :lol: 

I mean I am all ready for full out Spring but if there is a chance or something looks good...why the hell not. 

I do think one huge difference between now and what we've seen this winter is such an intense system that is going to end up southwest of Greenland. This is going to re-define the whole structure of the Arctic and this is helping to enhance a PAC which wasn't too terrible looking but going from meh to something noteworthy

Get the EURO suite to look like that and I'll grab the laptop.

Yep. Not biting unless other guidance latches on…but particularly the euro. GGEM and Ukie can do what they want but if GFS/Euro start agreeing then it’s a legit threat.

That is actually pretty ominous mean at hr 135....

oh f so it is... jesus

here's the 00z vs 12z run correction for D6:   I will also add ...this happened last week, folks.  We had a run or two where this huge single run explosion of presentation lurched on, then.... vanished.   I remember saying to Will in a post back then, that it seems like there may really be something there worth monitoring, but perhaps something peculiar about the model challenges IN in this period, were/are just masking it.   ...Sometimes a run gets through the mask so to speak -    we'll see...

something is going on that's a little off here.

you don't get the entire ensemble mass to move as dramatically as this, in a single run - at D6 no less...   It's one thing if the operational version meanders off into a fantasy for a run or two.  But these giant movements have been sharing the space, en masse, systemically at the same time. 

You probably don't recall my mentioning last week with all the noise in here... that there may be something legit there, but it's perhaps ( supposition here...) just being unusually masked by the circumstantial hemisphere of shenanigans going on... 

This thing did this pop up out of nowhere act last week on a couple of runs by the way.  Went from barely discernible to an ominious look...   , only to vanish.   It's been yawing back and forth with very odd variance

AI has nothing along with the euro 

 

just a phantom storm by the gfs 

Not sure I would describe it as a phantom storm by the gfs. It's a product of phasing...the GFS is more favorable with both streams and promotes a better likelihood for phasing. It's not like a GFS solution doesn't make sense. If the GFS solution didn't make much sense then I would agree it is phantom but it wouldn't take much from the euro to output something closer to the GFS...and on the other hand it wouldn't take much from the GFS to lessen this idea.

the CMC and UKMET are also much better looking out west. I am definitely taking the GFS with a grain of salt but it's not that far off, and the PNA has been trending better for a while now

Yeah it's the age old dilemma of whether the model run can actually happen or not. 

One has to remember it's about probability's > 0 and < 100  ... there's not absolute.    For starters, the models are not putting out solutions that are physically impossible.
