"A narrow but intense band of snow is working south from Wisconsin," ABC7 Meteorologist Mike Caplan said. Moderate to heavy snow - up to 2 inches -- is expected to fall between 1 p.m. and 4 p.m. in the Chicago area.
"While the amount of snowfall may not sound like much, the potential intensity and timing are likely to play havoc with the afternoon commute," Caplan said.
The northern suburbs will get hit first. Already, visibility in Wisconsin where the snow is currently falling is only about 1/4 mile.
Drivers are urged to use caution, and allow for extra travel time.
