August 10 - A MidWest Derecho for All Times

On August 10, 2020, a line of severe thunderstorms covered southeastern South Dakota and northeastern Nebraska across Iowa, northern Illinois, plus southern Wisconsin, Indiana, southwestern Lower Michigan and western Ohio. This land mass we are talking about today stretches 770 miles (1240km)!  And it was no marathon, this was a sprint….it took only 14 hours for this to do what it did this day in weather history.
