Looks like shear is gone.
Perfect radial symmetry on the cirrus outflow from the currently firing tower.

The HWRF model shows the center bouncing around and very slow deepening for the next 12 to 18 hours after which it ramps up fast. I don't think we'll see much improvement today.

This is spectacular.. with radial gravity waves and "bow shock" at the leading edge. and the immense pressure wave that was thrust outwards!

Just noticed you can also see a gravity wave expanding out westward.

Wow, Sally looks so much better than even a few hours ago. I know HWRF doesn't really ramp it up until tomorrow, but I wouldn't be surprised if it strengthens quite a bit today based on how it currently looks. Below is Sally 3 hours ago vs Sally now.

Isaias had a similar impressive convective bursting pattern E of FL, prior to steadily intensifying. Perhaps Sally will start ramping up this afternoon/evening.

Sally, that girl, is getting going, amazing deep convection. We will probably see the LLC and MLC start getting stacked little by little during the day today.

If I'm going to be smacked by Sally, she needs an eye. I'll stare right into her eye and spit.

I need to make one more run to the store. We're going to start feeling this soon, I think. Not looking forward to no electricity or AC.

Its picking up the high CAPE pool that always sits offshore of Houston.

As others have mentioned what an impressive explosion of deep convection radiating out in all directions. Looks like a bomb went off. One would think this would be the beginnings of steady intensification.

The current visible satellite Loop is a perfect example of the atmosphere being a fluid. A rapidly Rising thunderstorm hit the boundary that is the tropopause and it could only spread outward with gravity ways and all that. What a beautiful image.
