The Children's Blizzard (also known as Schoolhouse or School Children's Blizzard), January 12-13, 1888

The day started out warm, but a blizzard came out of nowhere and met a cold front, causing the temperature to sink to -20º F (-28º C) and creating a deadly snowstorm. 235 people were killed, most of them schoolchildren.

A few weeks later, one of the most severe recorded blizzards in the history of the USA occurred.

Snowfalls of 20–60 inches (51–150 cm) fell in parts of New Jersey, New York,Massachusetts, and Connecticut, and sustained winds of more than 45 miles per hour (72 km/h) produced snowdrifts in excess of 50 feet (15 m). Railroads were shut down and people were confined to their houses for up to a week. – according to Wikipedia.
