This region of enhanced diffuse reflection was further highlighted in GOES-16 True Color RGB images from the CSPP GeoSphere site (below).
The corresponding GOES-16 Low-level Water Vapor (7.3 µm) images (below) showed an area of orange enhancement that likely represented rapidly-descending (and hence warming/drying, via adiabatic compression) air within the lower troposphere, which was rotating around the southeastern and eastern edge of the lobe of deep convection.![](https://cimss.ssec.wisc.edu/satellite-blog/images/2022/12/atl_wv-20221212_180117.png)
