CHICAGO -- The National Weather Service has extended winter storm warnings in the Midwest and now expects more than a foot of snow in parts of Illinois, Indiana and Michigan.

The warning for northern Illinois and northwestern Indiana will now be in effect from 9 p.m. Saturday until 6 a.m. on Monday.

Ten to 14 inches are expected, especially near Lake Michigan.

Central and southern portions of Illinois and Indiana will see a rain-snow mix at the start of the storm.

The timing is bad for Super Bowl revelers, as travel on roadways could become hazardous.

National Weather Service meteorologist Ricky Castro says it will be the most widespread winter storm so far this season, as it barrels into the Midwest and maintains its intensity farther east into New York and Boston.
