The National Weather Service canceled the winter storm warning in northern Illinois hours earlier than expected today as the snowfall began tapering off.

In Rockford, heavy, wet snow downed power lines -- leaving more than 4,000 ComEd customers in the dark at one point. The storm dumped more than four inches of snow on Rockford overnight -- bringing the city's total to more than 63 inches this year.

In central Illinois, overnight snows dumped up to four inches on some areas and winds are expected to cause some problems with blowing snow.

Meteorologist Casey Sullivan says temperatures in the Chicago area will remain around the freezing mark before falling to the 20s this afternoon.
