Supercell signature?

I recently took some time to learn more about determining storm activity with radar as it is a useful skill for the line of work I want to get into. After learning about supercells and spotting tornados, I decided to take a look on Windy's wx radar just for fun. I notice that this radar return displays somewhat of a hook between Nashville and Bowling Green, lining up with an extreme tornado watch for nearby areas (reports taken from Windy app). Could this be an embedded supercell? My apologies if this seems like a stupid question, I am genuinely curious. Thanks!
