To me the impact of Matthew into our region has more to do with the phasing shortwave that is crossing the nation as it does with the exact track of Matthew towards the Carolinas. For example, last night's 00z GFS had a strong & south shortwave and eventually phased with Matt....this AMs 6z GFS isn't as strong, and you see the result.

At least it's close enough in time now that it shows up on the ACK MEX guidance.

Eye looks a little wonky, but has become ringed with really cold convection this morning, possibly indicating a bit of strengthening. Heading pretty much north along 75W. Haiti expected to get 25 inches of rain with lollis to 40. Disaster for them, especially considering their depleted landscape.

There was a noticeable shift back west in both the hurricane models and the 6Z gefs and the hurricane models, but let's be honest there has been plenty of wobbling back and forth and until some of these key issues with the speed and depth of the trough approaching from the MW and the strength and placement of the blocking as well as the effect of that other low to the east of the storm there is really nothing completely off the table. A Euro solution would be very minimal in terms of sensible impacts through 240, although it seems to be an eastern outlier.

06z actually more of an impact for SNE. Heavy rain and then very strong winds as Matthew departs. 00z not as windy thanks to inverted trough...:unless you are on CC. 

 

  Euro guidance still pretty far offshore although seems like some good spread on ensemble.

God, there isn't any aspect of meteorological phenomena that I loath more than inverted troughs....aside from the 1/20 year occurrence that your BY gets smoked with their wintery fruits, they are nothing but a lame attempt at both the atmosphere and computer guidance alike to reconcile the fact that nothing much is really going to happen, aside from a demoralizing waste of potential.

 

They have been showing up more on recent runs, and it makes me want to sprint to the toilet.

What a vile turn of events they are-

It rips gusts well over 60MPH for all. If you can't get excited for that..perhaps begin writing winter forecast

Looks to be intensifying to me....larger eye implies that it has restructured, or in the latter stages of doing do.

Likely just some high clouds shrouding the eye.....would think that clears by afternoon...everything remains on the table.

That's what I figured....it has to be more to do with the upper interaction with the trough because it doesn't cross much land, regardless.

Early 12z guidance has a bit more convergence up into the HAT area.

That is also a much tighter clustering than we have been seeing. I think the 06Z GEFS did a great job of showing three different camps of possibility with this system:

1: Missed phase and out to sea cluster
2: Faster storm progression with phase for impact into ME/points east
3: Slower storm progression with phase for impact into SNE

I still think #1 is the most likely option at this point, especially with the Euro, which has been nailing Matthew's track so far not on board. Still, we are talking the 144 hour time frame here and I am sure a lot will change in either direction in the coming days.
