Discussion
Low pressure has moved nearby in the overnight hours and there will be occasional rain today that can still freeze on some untreated surfaces during the early morning hours in the far northern and western suburbs. Dense fog is also possible today as the slightly milder air moves on top of still relatively cold (and moist) grounds. A strong cold front will push through the region early tonight and winds will become gusty behind it and it'll stay moderately cold overnight and on Wednesday. However, an even colder air mass will charge into the region late tomorrow after the passage of an Arctic cold frontal system. That system can bring some snow shower activity to the area later tomorrow and then it'll turn windy and sharply colder tomorrow night and Thursday with the coldest wind chills (and temperatures) of the season so far. Some moderation in temperatures will return by the end of the week.
