The January 31 – February 2, 2015 North American blizzard was a major winter storm that plowed through the majority of the United States, dumping as much as 2 feet (24 in) of new snowfall across a path from Iowa to New England, as well as blizzard conditions in early February 2015. It came less than a week after another crippling blizzard which impacted the Northeast with 2–3 feet of snow. It was the first of many intense winter storms to occur in the nation during the month of February, partly in due to an ongoing cold wave that was beginning to take shape shortly after the storm subsided.
Ahead of the storm, residents mainly in the Midwest prepared for potential whiteout or even blizzard conditions. The storm dropped as much as 19 inches (48 cm) in the city of Chicago, Illinois, making it their fifth heaviest snowstorm on record. Up to 15 people were killed by the blizzard, and it knocked out power for hundreds of thousands of people.
