I just want to post a friendly suggestion...When everyone is posting shots of radar scans of supercells, you may want to indicate the exact location of the storm especially during a severe weather outbreak like this that covers a lot of real estate. Sometimes its hard to tell what city and state the storm is located. Thanks.

Yep. Having followed Michigan weather for a little while, this is a pretty nice event for them.

Sure is. Still a little concerned with how supercellular storms are not getting warned on, even though we had a couple strong tornadoes a few years ago that weren't warned, and a non-warned tornado death last year...
