Entire Thies Family
This day began as an afternoon drive up the Mississippi River Road to Pere Marquette Park, north of Grafton, Illinois with my family.  Upon getting to Grafton, the radio alerted me to a severe thunderstorm that had formed about 25 miles to the west heading due east.  We ended up just waiting around for the storm to come to us over the river and hoping for a drive through the core to see hail.  There was no hail, but it sure became an enormous rain event.  Several inches of rain fell within an hour.  It created a flash flood event in downtown Grafton.
