Thunderstorm follows the course of a storm through midwestern farm country minute-by-minute, hour-by-hour, from late morning into late afternoon. As always with Arthur Geisert, it is a meticulously executed and visually stunning piece of work. Other than the timeline that runs along the bottom border of the illustrations, there is no text, and the illustrations are continuous.

Through keen observation, Geisert beautifully captures the nuances and details of a midwestern thunderstorm, from the ever-changing color of the sky, to the actions of the human inhabitants, to the reactions of the natural world to the wind and rain. America's heartland is somewhat unfamiliar territory in the realm of picture books, but in Thunderstorm, Geisert has provided readers with valuable, breathtaking insight into one of its most natural occurrences.
