• A Lake Michigan-driven cold front is bringing a sharp temperature drop to the Chicago area, with highs falling into the upper 50s to 60s by Thursday.
• Inland areas experienced highs in the 70s Wednesday before the cold front arrived, while lakeshore temperatures dropped into the lower 60s.
• Clear skies and calm winds Thursday night into Friday morning could lead to patchy frost in outlying suburbs as temperatures dip into the 30s.
