Tropical Hurricane Isaias

Maybe that can protect it against any existing shear?

I dunno but when you look at the big picture of the latest fix showing the LLC closer to being under the MLC, the outflow looking a lot better....I mean it just looks like this thing is about ready to go off......it just has that look right now like if gets even a little opening its off to the races.
 
Satellite imagery is amazing tonight it looks like the main cluster of thunderstorms is dragging the other cluster of high topped thunderstorms from the East into the center.. it almost looks as if they may try and start to dance around each other around the center ... can anyone explain the phenomenon?
 
Interesting apparently there is a eyewall now.

I'm not sure if I can answer this, but one thing I did notice earlier this afternoon and evening was the advent of the undercutting shear was starting to deflect around Isaias.

Some of the thunderstorm blowoff was being directed SE on the SW and Southern side of Isaias... meanwhile, to the NW of Isaias, I started seeing thunderstorm anvils blowing off more ENE and NE away from Isaias to the north...

While the undercutting shear has continued to be quite strong, it also appears it has been continuing to enhance the vigorous convection via divergence in the undercut...

I've been seeing a seemingly angle shift I the CDO starting to see a push back west and NW in the convective edge and some realignment/attempting to wrap around on The NW side...

Also it seems like the MLC has been moving NW trying to "meet up" with the LLC that's moving NNW... I think we MIGHT see an upgrade to a hurricane at 2am....as Isaias attempts to stack a little more vs during the day Sunday... but if it wasn't for the fact that the circulation wasn't well established, Isaias would have eroded down to a scattered mess.
 
0Z Euro: continues the NE trend of landfall toward Myrtle Beach and away from CHS, but that doesn't at all mean CHS wouldn't still have quite significant effects: Be safe everyone!

1st shower here from the storm, within a far outer band coming onshore. Hoping to get 1” or so total of much needed rain. And with that, night night.
 
Your morning clown wind map update, tried to get these with the center as close as halfway through NC as possible timing is anywhere from 2am to 9am.....obviously the winds will be the same north and south of this general idea

He has 18 hours. Unless he pulls a bertha it looks like a 75 to max 85mph landfall. Woke up thinking he might have already reattained cane status but he just cant get over that hump.

The window for that is when he is off GA/SC more so I would think in the next 6-8 hrs if that was going to happen we would see signs it was occurring......all it takes is for the storm to drop 5-10 mbs in the last 6-8 hrs before landfall to push this from 75-80 mph to a 90-100 mph type storm....
