Yes , lets see what the day brings. TPC seems pretty keen on the idea of development. Lets see if the shear relaxes a bit today.

Also 1995 had its weak storms to. One or two of them mean alot this year.
Matt,
The latest quickscat was from 0928Z yesterday morning. This morning's quickscat isn't in yet, and yesterday aftenroon's pass missed. BUt to answer your question, the numbers are what they are, sheared or not. I do not see any 40kt winds in the last pass about 24 hours ago, however. The highest uncontaminated wind estimate is 25 kts. You cannot use the black barbs because those are likely "rain-contaminated", meaning there are clouds there and the wind estimate may be for a point well above the surface.

I must chime in this morning. Ex-TD10 is lookingmuch better this morning with the nice feederband developing SE through NE of the center.
In addition deep convection beginning just to the N of the LLC. This could be the true awakening this time around.

Agree the shear has abated big time the T-Storms are not being blown off the top this morning..

A 1012 MB LOW...REMNANT OF TROPICAL DEPRESSION TEN...IS CENTERED
NEAR 17.5N59W MOVING NW 5-10 KT. CONVECTION HAS REGENERATED
AGAIN TONIGHT BUT HAS NOT REDEVELOPED INTO A TROPICAL SYSTEM.
CONDITIONS ARE BECOMING MORE FAVORABLE FOR REDEVELOPMENT AND A
RECONNAISSANCE FLIGHT IS SCHEDULED FOR LATER THIS AFTERNOON.
SCATTERED MODERATE/ISOLATED STRONG CONVECTION IS FROM WITHIN 120
NM RADIUS OF 18.5N58W.
The above is the 8 AM Discussion.

Water Vapor loop is interesting.
ex- TD10 looking better....
Now someone please explain what i'm seeing here. Looks like a ULL
to the NW of ex-TD10 moving westward. If so....what if any effect would
this ULL have on the course of our system?
Also whats happening to the north? I see some dry air there but
the system is coming down.... Is that a blocking high? If so...depending
on how far south it moves and the timing of any development....its possible TD10...Jose...whatever if anything...could get trapped and maintain a w or wnw movement.
Am I right on any of what Im seeing....or should I go back to meteorology101?
OOPS....forgot the link....heres the water vapor image I was lookin at...

I can't really find the center this morning. My initial impression was it could be way up at 19N/61.5W. But it could be down near 18.5N/59.7W. Cirrus is obscuring the low-level cloud elements. Could be it's gone, too, but more likely just hidden. If it's down near 19N, then it's not looking too healthy this morning with all the convection to the northwest moving away.
As for the model guidance this morning, note that the dynamic models are beginning to show a turn when it reaches the Bahamas, but the static BAM models show continued westward motion. I would remind you that the BAM models should not be used out of the deep tropics, as they perform horribly in a changing environment. This is evident in their performance with Franklin a few weeks ago:

wxman57:
I'm confused.
I see the model plot above (AL06) showing the turn at the Bahamas from 25/75 but when I look at the Current TPC/NHC Model Plots from Weathernet (sorry I can't paste it here; not sure how to do it although I see them all the time!); they show a west movement almost through the Fl Straits never even reaching 25/75.
Which one is the correct current plot?
Thanks for your guidance!

It does appear as though there may be a significant trof along the east U.S. coast as "Jose" approaches late in the weekend/early next week. That trof could well steer "Jose" off to the north before it reaches the east coast. No guarantee of that yet, though. Just don't pay much attention to the non-dynamic BAM models now. Look at the dynamic models.
Oh, and I asked a coworker where he thought the center was today, he guessed 19N/59.5W. So that's 3 different estimates. Could well be it's nowhere or it's too broad to identify. I think it may be reforming north and west in the leading mass of convection.
