Context

Background

The January 2019 polar vortex was among the most extreme cold events to affect the Midwest in decades, bringing air temperatures of -26 degrees Fahrenheit to Madison and wind chills as low as -48. The Wisconsin Department of Health Services issued warnings that exposed skin could suffer frostbite in as few as 5 minutes under those conditions. UW-Madison -- which rarely closes, having done so only a handful of times in its history -- shut down from 5 p.m. January 29 through noon January 31, a 43-hour window that Chancellor Rebecca Blank confirmed was the longest closure in the university's history. Across the Midwest, universities from Illinois to Indiana canceled classes and governors declared states of emergency. At Indiana University, nearly 25,000 people signed a Change.org petition demanding class cancellation before the university relented. The US Postal Service suspended mail delivery to parts of Wisconsin and Illinois -- the first such suspension in decades -- and at least six deaths were attributed to the cold wave nationally.
