Persistent Low over Midwest?

What's causing this cold rainy low to sit isolated over the Great
Lakes for days, instead of moving somewhere else?

With that much activity, you'd think it would wander off.

When it rains for days and nothing's moving, that's another matter,
but this one is actively staying put.
