In the sequence of radar images below, you can see how quickly the storm wrapped up as it crossed northern Crawford County.   The last image shows rotation within the storm west of Marengo.  The rotation was very strong, and we were amazed that there was no tornado touchdown!  Of course, this storm would go on to produce an EF4 tornado just one county later.  (Note, too, the second super cell coming up behind it along the same path!)
