RECON found extrapolated pressure just above 966mb - obviously the actual dropsonde will probably be a touch higher. Also had an unflagged 92kt reading as they got close to the center. Let's see what the 'sonde shows. 

That would be a steep drop in pressure since the 5am advisory.

It is amazing to me how, in the face of stiff southwesterly shear, Matthew continued to intensify and do so rapidly. If the shear ever were to relax, this could get really nasty. 

I'm worried for Jamaica. The 06z HWRF and GFDL would both put Kingston into the Northern eyewall.

That NW quadrant has consistently been the fiercest part of the storm, even when convection wasn't present. Not sure how often that happens.

The NW quadrant is the right front for this storm, so for a westward moving storm it's not rare. It is a little weird that it had the strongest winds when there was no convection though.

But not the nearly 11 year streak since a major has made landfall in the US.    Don't see any features to change that on this one.

Baby steps. Most the systems that have made it to the Western Caribbean in recent years have either gone into Central America, Mexico or OTS.

What makes you think that?

Previous history with models (yes, some 10-15 years ago)...with TC's/TS's/H's tracking through the C. Car.....for whatever reason, time and again, the models seem(ed) to always have a bias to turning these systems too early as they reach the western most portion of the STR.  I'd look for the model consensus to start shifting westward over the next day or two...along with the official NHC track...

You still think it goes sharply out to sea from there or just goes inland north into the Mid Atlantic?

Still way too early to speculate on the path after a W/C. Cuba/S. Florida impact....the synoptic setup to the north certainly isn't being modeled consistently enough to even "guess" at 6-7 day lead times, the eventual interaction/track.
