Tricky Storm Movement

I wasn’t sure where to ask this question so I figured I would ask it here…

I’m sure this is a very common phenomenon but I just personally haven’t noticed it most likely…as it relates to the confirmed tornado in Armada, Michigan last night.

The storm track for the Armada tornado was on a SouthEast track and upon reaching Armada, it took a rapid 90-degree turn to the NorthEast. I know storms can shift, often with little warning, but this one seems to take a rather abrupt track change, and I don’t see much of a mechanism for that change. Hoping some of the experienced Mets can provide some insight as the other two storms also in the radar images, keep marching on a SouthEast track… it’s only the Armada, MI storm that abruptly changes.

EDIT: This is from the KDTX radar at 20:30ET on July 24, 2021

I'm not great with this stuff...but on the reflectivity loop, it looks like there is some sort of cell merger that takes place in that area??
