While snow will slowly taper off in most locations around the Chicago area, the focus will soon turn to the dangerous cold and ferocious winds that will grip the region in the coming days.
A winter storm warning will remain in effect for northern Illinois and northwest Indiana through Saturday morning, not because of snow but because of wind chills plunging to nearly 40 degrees below zero and wind gusts in excess of 40 miles per hour.
Snow will continue in parts of northwest Indiana, including Porter and LaPorte counties. In LaPorte County, a “travel warning” has been issued, with residents asked to stay off roads because of dangerous conditions.
