Nice tick NW on the GFS16. Good to see the H5 SW sharper and dig a little deeper. Stronger SLP. Overall system looks a lot healthier run-to-run. We take.

This particular trend movie is exquisitely useful for this specific scenario - LOL

 

Seriously though ..it wonderfully exemplifies the high degree of sensitivity in the correct mass-field handling of the totally integrated field.  The compression locks the whole thing from JB to Florida...where if the N/ stream SPV N moves even a little bit,  en masse the flow geometry all he way to Florida adjusts in concert - the wave ends up more NE trajectory instead of E and that enhances cyclogen response... and blah blah -   But, notice the N / stream is slightly less suppressing across this sequence of frames.

Nice contribution !

To Will's point earlier in the day (other thread...), the NAM as an 'isolated sweetener' really cannot be trusted, but trend establishing over the bevy of guidance sources lends credence.

( Obviously we don't need "reminding" that trend is not the end...so this is an evolving scenario still  - just sayn' just sayn' )

The ICON - in fairness - had major short duration impact by this system over a couple runs recently ... back when it was centered more on the 8th.  Also, prior to that, the Euro as we know was having an raging skizoid break with it - ...it's probable that it's governing mechanics in the general eddy were always there but the model tech at this state of the art is still lacking when there's this kind of velocity saturation/compression maelstrom characteristic messing with coherency.

So we get closer in time... his system's governing mechanics appears to have been moved up in time, ...more 7th proper.  That in of itself is actually a nod in favor of this thing being a real mechanics presence in the flow, because the flow is fast and the correction would tend to be to move things up - spacial-temporal placement during fast progressive flow constructs still corrects sooner.. etc.  Probably, this gets earlier yet right down to now-casting ...and ends earlier too...

I'm sure other's have noted this ... but just in case -

The 72/78 hour GEFs have all the spread on the NW side of the consensus cyclone track - which as 101 deterministics go ..that's typically where we'd see future model runs correct toward. 

Noting at 84 hours, the spread persists, with some deep members there, too - few of which are < 980... In fact, all the more depthy members are in that NW skew plot, which seems to suggest there is some track sensitivity based upon the intensity -

Euro/EPS outta be a hoot -
