That system/ trough has been getting a good bit of my attention.
Around 10am CDT this morning it had a perfect CDO look. Only the western 2/3 of the CDO was onshore.

Tonight the un-enhanced IR is showing some of the nicest striated bands that I've seen in the last few years. ( see my attachment above) Also of note is the quantity of lightning seen in the eastern ( offshore ) semicircle. In the attachment the lightning is the bright bluish-white specks in the RGB enhancement.

I'm also keeping an eye on the circular wave moving through the Lesser Antilles. More out of curiosity than climatology. Large arc type wave moving toward the NW, where most waves would be moving due West.

I'll have to look at the data in that area.
