Many supercells popping up over Lake Michigan, heading east

Numerous supercell thunderstorms are beginning to pop up over Lake Michigan and are heading east at roughly 40mph:

The question remains whether or not they'll hold together as they make landfall on the western edge of the state, or whether they'll merge into a line as is currently being predicted. Such a bowing line could produce a fairly decent damaging wind event. I'm noticing modest rotation in some of these cells, however I still believe the tornado threat will remain low, especially as the discrete nature of the storms changes to become more linear.

I do expect a severe thunderstorm watch to be issued for the western portion of the state within the next couple hours.
