"Chicago Endures Frigid Temperatures and Dangerous Wind Chills"

Despite dangerously cold wind chills reaching as low as minus 26 degrees in Chicago, two men continued their routine of jumping into Lake Michigan, emphasizing the mental health benefits and endorphin rush. The National Weather Service predicts the bitterly cold temperatures to continue through Wednesday morning, with wind chill warnings in effect. The freezing air mass is the coldest Chicago has seen in five years, prompting cancellations and delays in transportation and flights. Activists criticized the city for not offering enough warming options for homeless people during the cold snap, while a nonprofit in Englewood is growing tulips in anticipation of flower-gifting holidays.
