Chicago: Snow may interrupt PM rush hour

A fast-moving clipper system is expected to move southeast across the Midwest tonight on a track south of Chicago and is expected to deliver a significant snowfall in the 2 to 5 inch range, with the heaviest amounts across the north portions of the Chicago Metro area, mainly north and east of a line from Rockford to Valparaiso.

Snow is on its way- just in time for a messy Tuesday afternoon commute in Chicago.

"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.
