CHICAGO (CBS) -- As Chicagoland braces for historically cold temperatures early next week, part of the area could potentially see another half-foot of snow before then.
The National Weather Service has issued a Winter Storm Watch for the far southern suburbs and Northwest Indiana.
The counties under the watch are: Ford, Iroquois, and Kankakee in Illinois and Benton, Jasper, Lake, Newton, and Porter in Indiana.
That area could be hit with up to six inches of snow, while the city and suburbs to the north and west of the watch area might get around two inches.
The snow is expected to start falling on Saturday evening and end on Sunday morning.
Periods of heavy snow, along with northwest winds of 15 to 25 mph could result in considerable blowing and drifting snow with significantly reduced visibility.
Then, a major blast of cold air will hit the entire area.
Temperatures on Sunday night, Monday, Tuesday and part of Wednesday will remain below zero.
There is also the potential for record-setting cold next week.
The record for lowest "high" temperature for a single day is 11 below zero, and there is a possibility that Chicago could tie or break that mark on Monday.
The coldest low ever in Chicago is 27 below zero. Low temperatures on Sunday and Monday night could approach 20 below.
