What caused the warmth?
Meteorologists say that El Niño, as predicted last fall, was the primary driver for the warm weather pattern that persisted throughout the winter. El Niño typically produces unusually warm winters across the northern tier of the nation.
AccuWeather chief meteorologist Jon Porter also said that our warming climate also contributed to the unusually mild conditions for much of the country this winter.
