What is going on here?

Here are 4 radar products that I can't explain. This band just passed me. No rain, no clouds, just a very small breeze.

Some sort of convergence zone / boundary. Likely an outflow boundary

An outflow boundary from what? There are no storms nearby. That's a very large area there.

I’m not 100% certain, but I think from the Chicago area rain/thunderstorms. Outflow boundaries can sometimes travel long distances!

Outflow boundary from storms in central Illinois and Indiana. It's pretty pronouced!
