Event Summary: May 16, 2019

A slow, south moving cold front and an outflow boundary from morning thunderstorms over northern Illinois combined with a hot and humid environment to produce widespread showers and thunderstorms across eastern Iowa and northwest Illinois overnight. Several thunderstorms became severe, and produced large hail and damaging winds. Quarter sized hail was reported across Clinton and Iowa counties, while destructive winds of 70-90 MPH were reported Iowa and Washington Counties. 

In addition, torrential rainfall amounts of 1-2 inches were reported along the I-80 corridor as storms slowly moved across the area. This lead to flash flooding across many major roadways, including I-80 near Coralville and Highway 965 in Oakdale.
