The snow departs-the cold arrives


The Blizzard of 2011 is just about history as snow has ended across most of the Chicago area with the exception of some lingering lake-effect in northwest Indiana. In the wake the snow, arctic air is flowing into the area on gusty northwest winds and the National Weather Service has issued a wind chill advisory for the Chicago Metro area as well as most of northern Illinois, southern Wisconsin and northwest Indiana.


The wind chill advisory will run from 9pm this evening until noon Thursday with wind chill values expected to drop as low as 20 to 25 below zero in the Chicago area and  as low as minus 30  west of the city across north central Illinois.


In the Chicago area overnight lows are expected to range from about 3 below in the Loop and near Lake Michigan to as low as 14 below west of the city in the Fox Valley.  On Thursday, Chicago area highs will struggle to reach 12 degrees.
