A "clipper" system that developed overnight and brought a wintry mix of rain to the south and snow to the north and west is expected to continue moving across the Chicago area Tuesday, creating slushy and slippery conditions for the Tuesday morning commute.
According to the NBC 5 Storm Team, counties to the south, including Kankakee and Will counties saw rain as part of the system. Precipitation in counties to the north and west however is in the form of snow, Roman said, as more moderate, intense snow Tuesday morning moved out of DuPage County and headed toward northeast Illinois.

That "burst" of heavier snow is expected to hit Cook County just in time for the Tuesday morning commute, Roman said, adding that the weather was already leading to slick and slippery road conditions, as well as low visibility.
"Some slushy accumulations could definitely be possible," Roman said, as the snow continued to move from the western suburbs into Cook County. As of 6:30 a.m. NBC 5 Traffic Reporter Kye Martin said drive times on Chicago and suburban highways were already building as a result of the conditions.
According to Roman, the wet conditions were expected to continue through at least 7 a.m., with snow and showers diminishing through 8 a.m.
