I agree. "Some additional development." With 80% you would think it would say that development is likely later today or tomorrow.

Looks like overshooting tops really picked up quickly in the last few frames of that loop.

Also see it on the image here:

MIMIC suggests this area has done nothing but to continue to organize for the past 6 hours at least.

Looks like no upgrade at 5 PM but you never know what will happen in a couple of hours.

To my untrained eye, this looks close to being a minimal TS. upgraded later this evening maybe.

The 20-knt wind-field north of the LLC is a typical feature of a TD.

Not upgraded because the LLC is still poorly defined and looks to have multiple vortices on visible sat.

That didn't hold them back from upgrading Igor. Funny how things work.

UL winds appear to have improved since this morning.

Looks like there is more radial outflow in all directions as opposed to this morning when there was about a 10-knot UL wind blowing SW to NE exposing the LLC.
