The only problem with this is the other models are already in "poof" territory. Yes, they have something, but it slides south for the most part. Although, nobody mentioned the 6z RGEM which took a step toward the 0z and was better than it's own 0z run. It really is the Euro on an island of it's own, so "poof" is definitely on the table. It would be pretty remarkable tho. Link to comment Share on other sites More sharing options...

In the old day, we would of still been celebrating the 00z run Instead they torture us with off runs that only go to 90 hours so we are forced to use imagination from there on in time. 1 Link to comment Share on other sites More sharing options...

H2O Posted January 18, 2022 Share Posted January 18, 2022 22 minutes ago, DDweatherman said: It really is interesting over the years Steve that when the Euro has been on its own with a solution and the rest of the models don't have it, the trend is almost always for the Euro to trend to the others. This has especially been the case where it was bullish on snow (though thats probably when were paying the most attention). My recollection from being here over 10 years has been this: The Euro would show a solution(good or bad) and was often on its own. The other models(GFS, Ukie, CMC) would all be showing the same thing but at odds with what the Euro shows. Over time the other 3 would slowly come towards the Euro's general idea. The Euro would also adjust towards the other 3 but at a much slower rate and scale. Around 2 days out there would then become a consensus with all the models and they would each have subtle differences There have been times each model has "won" and others come to its initial solution. But each storm is unique IMO and the +/- of each model helps/hurts it for each one. 4 Link to comment Share on other sites More sharing options...

stormtracker Posted January 18, 2022 Share Posted January 18, 2022 Ok, another comparison..12z NAM is better than it's 2 previous runs and the 6z GFS. We got more energy out, but the northern stream isn't as diggity dog 2 Link to comment Share on other sites More sharing options...

I'd take 6-12" in a heartbeat (but kinda only if MBY was closer to 12"). Thing is...if we got 6-12" and SE VA got 12-18", I'd be maybe a little annoyed. 1 Link to comment Share on other sites More sharing options...

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. 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. They call it grapes? Do you know if it's available publicly for free? I'd be interested in checking it out. Link to comment Share on other sites More sharing options...

It did best with the next snow event and was better with the last one too. It’s still better than Gfs overall. That said we’re getting into the range all the major globals have been good. So if only one is off on its own that’s suspect. So I think if we don’t see some significant movement in the icon/Gfs/ggem today that’s a bad sign. I also suspect if we don’t see any improvement today the euro will begin to trend towards them. This is totally superficial analysis based on recent model behavior at specific lead times. I did not think the 06z Euro was quite as good as the overnight run.. or yesterday's 12z.. is this the beginning of the cave in? We will see!

weathercoins Posted January 18, 2022 Share Posted January 18, 2022 At a work meeting (law firm) someone mentioned that there is “going to be a big blizzard this weekend” and I said that’s not true. Guessing that they follow DT on FB. Anyway, would be thrilled to somehow lose my weather credibility over this storm. 2 Link to comment Share on other sites More sharing options...
stormtracker Posted January 18, 2022 Share Posted January 18, 2022 So, NAM is way closer to the 6z Euro than the GFS, FWIW. Which is 1/10th of a penny. 1 3 Link to comment Share on other sites More sharing options...
baltosquid Posted January 18, 2022 Share Posted January 18, 2022 Nam isn't too far away, things just happen too late. Definitely moving in the right direction. Still too far southeast for most of us, 95ish probably would have been furthest NW extent of flakes or just too far to get anything, but hopefully the start of a trend.
