A Winter Storm Watch for central and southern Cook County near the lakeshore as well as northern Lake County, Indiana is in effect from midnight to noon Friday.
A band of heavy lake-effect snow is expected to develop along the Illinois-Indiana border late Thursday evening, ABC7 meteorologist Larry Mowry said. The group will vacillate in Cook County and Lake County, Indiana through Friday morning.
Areas that see lake effect snow can expect total snowfall accumulations of 2 to 4 inches, with up to 6 inches or more possible in some areas if the band stops in one spot.

Snowfall rates of 1 to 2 inches per hour are possible and could reduce visibility to less than half a mile and lead to rapid accumulations on roads, Mowry said.
Some of the latest modeling shows the heaviest snow could fall in Chicago, Mowry said.
Drivers should expect hazardous road conditions during the Friday morning drive. Lake effect snow will likely affect the Dan Ryan Freeway, Bishop Ford Freeway, Skyway, I-80 and highways in Lake County, Indiana.
