Overview

A line of severe thunderstorms formed across southern Minnesota and produced damaging wind along and just south of Interstate 90 in southeast Minnesota.  Wind gusts reached 60-70 mph from just southwest of Rochester, MN to near Preston, MN.

As the storms moved into far northeast Iowa and western Wisconsin they were weakening but still produced gusts of 35 to 50 mph in many locations.

In addition, additional storms formed later that same night, into the morning hours of Friday August 19th, which brought several more inches of rain to parts of the region.  Some spots received 2-5" of rain which led to additional street and flash flooding.
