Cedar Rapids, Iowa, stood in the gunsight of an awesome derecho storm that hit the state on Monday, August 10, in the early afternoon hours. A derecho, usually associated with rapidly-moving bow-echo or squall-line thunderstorms, packs immense straight-line winds, often in excess of 100 mph—and it remains far more difficult for meteorologists to predict than garden-variety cells and tornadic rotation.
