The air was oppressive, clinging like a hot, damp blanket draped across the heartland of the United States. Despite a cooling rain the previous night and a thick blanket of clouds through the morning, midday sunshine pushed temperatures past 90 degrees by early afternoon in northwest Iowa. After a warm and dry beginning to the summer, rain was a welcome sight for the many farmers who wrested a living from the fertile prairie soil. As towering thunderheads began to burst into the muggy afternoon skies, however, concern began to grow. A stiff breeze picked up, blowing from the south and east with enough force to rustle trees and hold flags at attention. This, long-time residents knew, was cyclone weather.
