That is a real consensus of the Global models.

We can't even get a good fish which completely sucks.
I was thinking the same thing - so far this season is garbage. The atlantic storms look pathetic. They should ask the EPAC what the secret is

I'm not sure what everone is looking at, but Florence hasn't looked this "good" in days. The LLC appears to be relocating next to the convection, possibly near 20.6N/54.7W. That's a sign that the shear has dropped off and it's ready to deepen tonight. Finally looks like it's getting its act together.

But based on water vapor loop analysis, that pesky ULL is still there and you can see it entraining dry air into Florence. I don't expect any rapid strengthening or organization until that stops.

The visible shows the old LLC dissipating, but you can't really tell if a new one formed.

You got the latitud right but the longitud according to SSD is a tad more east.

It's not the best looking system, I agree. But it's not being "sheared to bits". It's expanding and becoming a large and broad system, and it actually looks better organzied than this morning with thunderstorms on the west side of the center and increasing now. There is a large anticyclonic outflow aloft, that causing the system to expand. Just as models have been showing. But the increase in size is happening first, before there is intensification.
You guys are trying to look for something small and compact, but that's not what this system was ever forecasted to be by the models.

The eastward shift in the models is understandable when you think about how Florence has made less forward progress than previously forecast.
These were the forecasts from 12Z yesterday for the 12Z position today:
GFS 20.4 55.4
GFDL 21.2 54.0
NOGAPS 21.1 55.6
UKMET 21.8 54.9
Average 21.1 55.0
NHC 20.5 54.5
Verified 19.6 53.1
Overall, while there was a fairly large north bias, the west bias was even larger. Point being is that Florence won't be as far along west as expected when the gap in the ridge opens up.

Nice to see somebody professional agrees with me.

i am on the fence as to what this thing might do
i would like derricks opinion (u posted as i wrote this nevermind i knew there was southerly shear)
the wv and visible tell two different tails
wv shows very dry air entraining and becoming INCREASINGLY dry on the west and south sides
visible shows llc apparently tucked under where convection was trying to fire earlier
is this what happens when a unusually strong trough in the central atlantic (4 days ago) spits out a big ull and everyone is hoping to see a big hurricane that effects no one and the dry air or shear turn out to be a bigger issue than forecast (what else is new)?

I'd accounted for another hour's movement in my estimate. That little vortex moved 51nm in 3 hours.

I see outflow developing in all quadrants, except on the SW Quad. On water vaper the loop you can see the ULL backing away to the west, so it makes sense that an anticylone aloft is developing over it.
