The winter storm is winding down, but you can still expect some challenges on the roads this morning. Monday’s sleet, snow, and high winds have dissipated. But temperatures that have fallen overnight have created patchy slippery spots on roadways.

Temperatures will continue to fall to just below freezing throughout the day. Flood warnings have also been issued for communities all along the Illinois River.
