Overview

Fast Facts:

  • A classic weather pattern for redeveloping rounds of thunderstorms took hold across the Upper Midwest into the southern Great Lakes regions.  This pattern is often referred to as a "ring of fire" pattern.  For more on the ingredients to this, see this graphic from a 2014 setup in our area.

  • The main impacts were heavy rainfall of 3" to 7" over the few days causing flooding, at times very rapidly, as well as numerous cases of thunderstorm wind damage, some of which were significant.

  • It had been a wet month for far northern Illinois. In the 30 day stretch of June 23-July 22, Rockford received 11.96 inches of rain. That was the wettest 30-day stretch for the city since 2007 (July 27-August 25, 14.39").
