CHICAGO (AP) -- Officials are gearing up for more snow on top of dangerously low temperatures in the Chicago area and north central Illinois.
The National Weather Service issued a winter weather advisory from midnight to 4 a.m. Wednesday. They say the area could get 2 to 4 inches of snow combined with dropping temperatures and that could make for a treacherous rush hour.
Chicago's O'Hare International Airport on Tuesday morning recorded a temperature of 6 below zero. That was the earliest subzero temperature at the airport since 1995.
Cities across Cook County were opening warming centers and the Chicago Department of Streets and Sanitation is preparing to deploy snow plows.
Gary Schenkel is executive director of the Chicago Office of Emergency Management and Communications. He's urging residents to check on their neighbors.
