CHICAGO (CBS) — Some Chicago residents are waking up to the first snow of the season and there's more to come. During the early Thursday morning commute, expect a few passing flurries/snow showers but no major road impacts. The widespread snow moves in after 7 a.m., which will aid in slushy accumulations on the roads and reduced visibility.

The ban is in effect through April 1 and prohibits parking from 3-7 a.m. on about 107 miles of major city streets, regardless of snow. Towing fees start at $150.
