A major outbreak of dangerous thunderstorms continues to slam areas from Nebraska to Illinois Wednesday morning with baseball-sized hail, flooding downpours, damaging wind gusts and isolated tornadoes.
Throughout Tuesday evening, an intense cluster of thunderstorms pushed across Nebraska with wind gusts 80 to 100 mph in some areas and had enough force to overturn a semi-truck.
Baseball-sized hail, high wind gusts and flooding downpours swept across Omaha, Nebraska, forcing the evacuation of several homes, according to Omaha Mayor Jean Stothert. This occurrence of severe weather is known as a derecho. Due to ferocious wind and torrential rain, derechos can also be referred to as inland hurricanes.
The northern extent of the thunderstorms will clip Chicago early Wednesday morning, bringing the threat for flooding as it continues into the Ohio Valley later in the day.
