History

Historical Context

The January 2014 polar vortex caused extreme cold across the U.S., with temperatures dropping to -15°F in Chicago and affecting over 200 million people. This event followed a pattern of Arctic air incursions, similar to previous cold snaps, highlighting the Midwest's vulnerability to such weather extremes. The cold wave also contributed to a 2.9% drop in GDP, disrupting various sectors.
