ABC 7 Chicago’s AccuWeather meteorologists predicted scattered and severe thunderstorms, some with tornadoes, would cross parts of eastern Iowa, northern Illinois and southern Wisconsin from midday Saturday through the afternoon.
Thunderstorms with very large hail and severe wind will affect parts of the northern and southern Great Plains.
Saturday’s projected severe weather comes after much of the area saw significant flooding last weekend.
That flooding was pervasive, shutting off power at Chicago’s Willis Tower and causing suburban residents to dry out their basements.
