You can see how the convection is beginning to wrap around the center on the southeast and east sides. The dry slot is also beginning to shrink some. I Harvey will get near hurricane strength if it continues organizing like it is now. Here is the link below for a visible satellite image of it. I am not sure, though, why the link is so long.
Not much shear over the top of Harvey - much less than yesterday, or even this morning. Convection is wrapping round the south side - I think this has a fair chance of getting to Cat-1 status by tomorrow morning.
The ULL is giving it fits pushing up right under it. It's hard to see in the visible loops. You can see in this loop 2 distinct lows both right next to each other (broadband only):
Harvey certainly looks MUCH better than yesterday. I say a Cat. 1 is definately possible. Or our 4th 70-mph TS of the season. That's starting to irritate me.
The convection is definately beginning to wrap around. I think that Harvey is just strong enough now to fight that ULL. It does look significantly more symmetrical, but there's still a while to go yet.
I think it has fought off the ULL already. The old ULL and Harvey's center seem to have merged or at least it looks that way in the big loop I posted, but I'm no expert.
