Despite warnings from weather and public safety experts that the extreme low temperatures Chicago is currently experiencing is especially dangerous to children, the elderly and family pets, it was not until late on Sunday afternoon that Chicago Public School officials announced that all city schools will be closed on Monday. In a news statement, Chicago Public Schools CEO, Barbara Byrd-Bennett said:
"The safety and well-being of our students is paramount," said Bennett in the statement. "Given, the dangerously cold temperatures and high-winds, it is in the best interest of our students for schools to be closed on Monday."
Monday's high temperature is expected to reach approximately 7 degrees below zero, with many parts of the Chicago area getting no warmer than 15 degrees below, and wind chills are predicted to range from minus-30 to minus-50 degrees.
One National Weather Service meteorologist, Edward Fenelon called Chicago's extreme weather conditions "life-threatening."
Interestingly, as of 8 p.m. on Sunday night, the Cook County Department of Homeland Security and Emergency Management website posted no weather warnings or updates in 2014.
