Timeline: How the derecho arrived in the Quad Cities

The derecho on August 10, 2020 wound up costing communities upwards of $11.2 billion in damages.

The Quad Cities area fell victim to the most expensive storm in United States history on August 10, 2020. The derecho came into the News 8 viewing area that Monday afternoon with 70 mph winds.  

The storm originated from a system of severe thunderstorms in northern Nebraska and southeast South Dakota that morning, ultimately spanning 90,000 square miles and impacting more than 20 million people as it made its way across the Midwest.  

In total, the derecho cost more than $11.2 billion in damages, taking down crops, trees, power lines, and buildings.

The first counties in our viewing area stared reporting high winds shortly before 1 p.m.  Cedar County logged 70mph winds at 12:51 p.m.' Henry County reported 58 mph winds at 12:55 p.m.
