Northwest winds will continue to gust around 40 mph overnight. Considerable blowing snow will create blizzard conditions at times, especially in open country. Travel is highly discouraged the remainder of tonight. In addition to locally poor visibility and drifting snow across roadways, the strong winds are ushering arctic air across the region. By daybreak Monday, temps across the Chicago area are expected to range from 5 to 10 below zero, with dangerous wind chills of minus 30 degrees or lower. Little or no recovery in temperature is expected during the day Monday.
