CHICAGO — Sorry, folks. It's still winter.
The National Weather Service issued a wind chill advisory in effect from 7 p.m. Wednesday through noon Thursday, during which wind chills could fall to 30 below zero.
"A strong Arctic cold front crossing Northern Illinois and Northwest Indiana by early this evening will usher in another round of very cold Arctic air," the agency said in its advisory.
The temperature could fall as low as 10 below zero overnight. Combine that with winds between 25 to 35 miles per hour, that could lead to "dangerously low wind chill values of 20 to 30 below zero."
Earlier this month, the wind chill hit 40 degrees below zero during a period that the city was declared "Chiberia" and temperatures fell below that of the South Pole.
