Children's Blizzard hit the U.S. plains states on January 12, 1888. The blizzard came unexpectedly on a relatively warm day, and many people were caught unaware, including children in one-room schoolhouses. What made the storm so deadly was the timing (during work and school hours), the suddenness of the storm, and the brief spell of warmer weather that preceded it. In addition, the very strong wind fields behind the cold front and the powdery nature of the snow reduced visibilities on the open plains to zero. People ventured from the safety of their homes to do chores, go to town, attend school, or simply enjoy the relative warmth of the day. As a result, thousands of people—including many schoolchildren—got caught in the blizzard.
