The center low-level center actually seems to be slowing in an attempt to hook up with the convection. Will be interesting to see if this happens. Shear has dropped to almost nothing and this may be allowing the catch up.

Looking at visible loop. Seems the LLC and MLC are getting very close to stacking.

That's what I noticed too, seems to be forming rounder structure to that area of convection.

Sally's definitely trying, I'll give it that.

It is a weird look, but looks like maybe a new LLC or the current LLC is relocating back to the east. Crazy looking.

100% the best it's looked all day. Maybe I'll still be proven wrong still.

We’ve been pointing out the naked LLC all day (which is now covered up), but Sally has consistently had excellent banding and outflow in its south and east quadrants, as seen in that image.

I am only a meteorology enthusiast who knows a decent amount about tropical cyclones. Look to the professional mets, the NHC, or your local weather office for the best information.

If the LLC and MLC can stack before the sun sets today, I definitely would not rule out an RI phase or two before landfall. It has just about everything going for it except for that pesky weak to moderate shear.

Do you think the center is reforming or getting pulled into the convection?

It is just doing a cyclonic loop as I mentioned this morning... a full refom east is not likley. but looping back to the deepening convection is occuring..

in the end I guess it is the same ...where the overall motion equals out to a slow drift wnw today.

It seems to be getting pulled into the convection, but the improved outflow may be exaggerating how quickly the alignment is happening.

The center isn't underneath the deep convection yet, but it's much closer than earlier. Seems more likely that the center is slowing in an attempt to get underneath the MLC.

Frame 2105 UTC the low level banding didn't appear further west.
Recon is almost there and this is getting important so laying down my bet on whether NOLA is going to have to evacuate in 6 months isn't a priority.

Persistent storms firing over the panhandle. Looks to be much less wind shear to the north.

The G-IV flight showing the shear has dropped to 10kts or less. only a matter of time before convection comes back in a big way.

also noted the lower shear in the satellite presentation.

It is important to note that a slower motion and stronger storm will more than likely put Lower Alabama into play for landfall. Some of the models still show this as a possibility. Even though they are barely in the cone (west end), I wouldn't sleep on the possibility. Recent experience with storms approaching from this angle tells me to expect a landfall more to the right than forecast. Just a hunch. NOT a forecast.

Shear appears to be relaxing as the cirrus outflow in the western section of the cyclone is improving. I expect slow steady intensification overnight.....MGC
