Tropical Hurricane Dorian

Looks like the NOAA plane didn't get far outside the center before turning around to head back in. I wonder if they're either about to fly back or want to get a definite reading from the N eyewall where they've been finding cat 5 FL winds.
 
Yeah this thing isn't coming back west.

NAM looks like some EPS members it stalls of the FL coast then starts heading slightly NW

NAM puts it in park off the FL coast for like 30 hours

just for the sake of argument, if ... if ... that were to happen, every model run for the last 10 days could be tossed ... because if ... if ... that were to happen, the entire dynamic set up (troughs, ridges, steering currents, SST due to upwelling ...) would have changed considerably ...

Why? Because the models say so now? The same ones that had it going into the Gulf a couple of days ago? You think they are right now, though, this far out? I don't get how people can forget how we have seen the models do this before with the track, going from one extreme to the next, and it end up adjusting more the closer we get to the middle. Way too premature to say it is going out to sea.
 
The trend is quite clear over the last couple of days. Nothing is set in stone with tropical cyclones, but you would think that as we close in, models are going to be more apt to get the general environmental setup right. Confidence increases in that idea as we see the various model suites converge in general consensus with track direction. Certainly a few miles here or there make a major difference, and such small details can't be defined exactly at this point.

But I think what we can start to agree on is that the probability of Dorian riding up the east cost of FL, remaining offshore and eventually recurving has gone up significantly over the last two days. How close it gets to some point along the SE coast is still up in the air.
 
Dorian keeps chugging west for much longer and all these model runs can head out the door, I know the stall wasn't forecast for a while but pretty much all the hurricane models there have a NE turn beginning soon.

I'd most certainly prefer OTS outside the islands but the way this has been going, I have to feel there's a 3rd trick coming and even 50-75 miles of difference will be major implications.
 
Another Import piece of the puzzle will be the evolution of the jet at 250mb. As the storm moves towards the coast, the jet's job will be to pull the storm further Inland or OTS. For the storm to go inland the jet needs to dig SE. The stronger the farther Inland the storm will get.
Heres the 00z, you notice It strongly dig positive. Stronger than 06z which is why Dorian moves further inland.

Agreed.... and for those saying it's not slowing down, well it is. This advisory down to 8 mph, that ain't fast and honestly it looks slower

This analysis and the one you did on the high to his east are key for us here in eastern NC. Angle of approach is everything with this setup. Is it NNE just inland and up heough the state or ENE staying 50 miles offshore. Very key components that are highlighted by these 2 features you've brought up.
 
Icon actually takes it SW a bit lol, close to landfall in southern FL, let’s see what the trough does to it
