MINNEAPOLIS — Students stayed home from school Thursday and several businesses were closed in parts of the upper Midwest as arctic air pushed wind chill readings to dangerously low temperatures.
A wind chill warning was in effect for northeastern North Dakota and northern Minnesota, with wind chill readings plunging to more than 40 below zero (-40 Celsius) in some areas. Forecasters from the National Weather Service urged people to limit time outdoors and bundle up, as exposed skin could be subject to frostbite in as little as 10 minutes.
In Minnesota, the coldest wind chill reading was in Fosston, in northwestern Minnesota, where the wind chill reached 48 degrees below (-44 Celsius), the National Weather Service said.
Minnesota’s Anoka-Hennepin School District notified parents that classes were canceled “due to extreme winter weather conditions in the early morning hours.” Several other districts were closed, and some had e-learning days, meaning that students received instruction online.
