A Winter Storm Warning takes effect in LaSalle and Livingston counties at 10 p.m. Friday and continues through 4 p.m. Saturday. A Winter Storm Watch was downgraded to a Winter Weather Advisory beginning at 1 a.m. Saturday in DeKalb, Kendall, Will, Kankakee and Ogle counties in Illinois and Newton and Jasper counties in Indiana.
Precipitation will move into the area overnight, bringing a wintry mix of rain and snow to areas south and west of Chicago.
