The climate phenomenon is a by-product of a years-long cycle of water temperatures in the tropical Pacific Ocean known as the El Niño-Southern Oscillation (ENSO) and has been in its cool phase for the past three winters -- a rare feat for an event that typically lasts for one winter, maybe two.

A split in the Polar Vortex led to one of the strongest cold air outbreaks in years, coinciding with one of the biggest storms of the year with winds across the Midwest and Great Lakes that grounded flights and continue to impact travel to this day.
