I see the euro still has a SoMD special for the weekend.  When the GFS gonna fold?   The American empire has had its day.  Hey is there a Chinese weather model?

Yes, it's called GRAPES: https://public.wmo.int/en/media/news-from-members/cma-upgrades-global-numerical-weather-prediction-grapesgfs-model-china

just hang your hopes on the sampling issue...that will get you through until its sampled then panic...does beg the question where does the euro get it's sampling data or is it just better at extrapolating...or none of those

Every time someone mentions "sampling", I die a little inside. Almost all meteorological information is shared internationally....nearly all modeling centers start from the same base set of data from which to choose/utilize. There are two main exceptions: 1) some data is from the private sector and has limits as to how it can be shared, 2) some places aren't allowed to use certain data from some entities; e.g., here in the US we aren't allowed to us observations from Chinese satellites which isn't the case at ECMWF/UKMO, etc. There can be other differences that are a function of data provider, such as who produces retrievals of AMVs, GPS bending angle, etc. Generally speaking, differences is in how the observations are used...not in the observations themselves.

There was something posted yesterday saying the Tonga volcano screwed up some sensors the Euro uses for initialization data and they were unsure when those would be back online. Could this be the reason the Euro is on an island with this?

No, see above regarding data. The signal that was in the "innovation" field, which is just the difference between a short term forecast and the observations. In this case, the signal is real as a result of the shockwave and showed up in certain observations that are used in NWP. I do not have it handy, but I bet we would see similar signals in other NWP systems for that same channel. Further, what was shown was just the information that went into that particular DA cycle and not the analysis itself. Even if that signal was put into the model, it would be very short lived....both in terms of that particular forecast but subsequent cycles. It has no bearing on the current set of forecasts.

Still nothing compared to what we used to achieve in these parts. Just delivering honest words in this regard.

I am going to enjoy this one for obvious reasons. These things don't happen often.

Every. Single. Post. 
 

I your goal was to be a dick, stop practicing. You’ve mastered it.

Dude, stop.  Wait until 12z before you descent into making us all miserable. It's 1000% better than the GFS still.

Lol im just going by what you all are posting. Plus all the euro sensors got swallowed up by tonga

Someone said the Europeans were struggling getting data because there was a shortage of weather balloons due to Covid. Can anyone confirm?

We be chasing another phantom ... again just for different reasons. Yall must be hurtin' after all of those historic years stuff like that doesn't cut it anymore.

It's just like Bob Chill said. We rarely time the big dogs we are reliant entirely on extended cold to get HECS.

And another

Makes sense to me. I went to lowes yesterday to buy weather balloons and they said supply issue are killing them

No. [Edit to add] And if there is a sonde missing for ECMWF, there is a 99% chance it's missing for everyone.

He’s on our radar.  We see it.  I’m just trying to give dude a chance to read the room. 

Well, my 2 cents, and that’s probably what it’s worth, is that he’s been in the center of the radar for years. He adds nothing to any discussion. No insight, no information, no humor, no camaraderie with others. Further, he will divert any discussion over to his doom and gloom outlook.

If you gave me mod powers for 30 minutes he’d be gone forever. 
 

Thank you and I’ll shut up now.

It only goes out to hour 90 and looks pretty much the same.
I was just going by randy and ralph word description before maps came out

My bigger concern is we have no other guidance close to what euro is showing and euro now is in its wheelhouse

From Walt Drag this AM. 

 

 

East coast snowstorm potential 21st-22nd Atlanta to NYC-Boston: Uncertainty exists on best target, and also where its all snow or freezing rain-sleet. The greatest uncertainty for me is the NYC-BOSTON-I84 corridor. No matter, there does appear to be a strong likelihood of a 5-10" snowfall, especially NC-VA-MD-DE.

But isn't the GFS seemingly moving toward the Euro? Not necessarily saying it will move all the way to it or we will get a big storm, but Euro has been rock steady for 4-5 runs now while the GFS is all over the place. I feel pretty good about where we are right now. Hopefully, we see the GFS take another step at 12z. Also would like to see the CMC take a step there as well.
