CHICAGO (CBS) -- Occasional freezing drizzle fell through early evening Monday, as a chance for stronger freezing increased. 

Freezing rain is likely overnight, resulting in slippery roads -- especially side streets and untreated roads. Sidewalks and driveways will also be slippery Monday night through Tuesday morning.

Ice amounts will be up to a quarter of an inch of accumulation, but perhaps as high as 0.30" in the southern suburbs. Snow is possible in parts of McHenry and Lake (Illinois) County by morning, allowing for a couple of inches of accumulation of snowfall.

Conditions are expected to improve gradually on Tuesday starting late morning as temperatures rise above freezing. 

Areas of fog develop Tuesday evening. Some of the fog could be dense through Wednesday morning. 

Rain and highs around 40 degrees are expected on Wednesday and Thursday. 

TONIGHT: Increasing areas of freezing rain Monday evening, then freezing rain likely overnight. Low 31°

TUESDAY: Morning freezing rain, snow to the north near the Wisconsin state line, then showers possible in the afternoon. High 35°
