Freezing rain and snow could make roads treacherous across the Chicago region today, according to meteorologists.
The National Weather Service this morning issued a hazardous weather outlook for north central Illinois, northeast Illinois and northwest Indiana. The advisory is in effect through 10 p.m.
Winter storm warnings have been issued for several counties in northwest and north central Illinois. Some parts of those regions could see four to eight inches of snow, according to Stephen Rodriguez, a meteorologist at the weather service's local headquarters in Romeoville.
The type and accumulation of precipitation will vary, but the storm will affect most communities across the region, Rodriguez said.
“Snow, sleet and freezing rain will be possible almost anywhere across the area, today through early Sunday," Rodriguez said.
An updated advisory this afternoon noted that areas along the Chicago lakefront are expected to remain warm enough to largely avoid the freezing rain.
The wintry mix will likely create slick road conditions even where snow is not likely, Rodriguez said.
By 6 a.m., some areas south of Interstate 80 were already seeing freezing rain, Rodriguez said. By about 10 a.m., areas including Cedar Lake in Lake County, Elburn in Kane County, had seen iced-up roads, but authorities in Kankakee reported that most ice on the roads there had already melted, according to the weather service.
Freezing rain and sleet were expected to arrive in Chicago by early afternoon and linger for several hours before tapering to drizzle in the evening. As of 6 p.m., the Chicago Department of Streets and Sanitation said they were sending out 75 slat spreaders throughout the evening and planned to monitor roadway to apply salt as needed into Sunday morning.
One to three inches of snow are expected to accumulate across Cook County early Sunday morning.
