I’ll be honest I’m stumped here. This could be a “hole punch cloud” that I talked about last week or it could be something entirely different. To me it looks like there is a contrail in the middle which would explain the hole punch cloud.
Through the movement is weird and to me pretty odd. Plus how about the nice turtle shell stratus deck it’s moving through?
Hat tip to Jim Loznicka of WJHG for pointing this out.
