CHICAGO (WLS) -- Extreme heat is in the forecast for the Chicago area Monday. ABC7 Accuweather Meteorologist Mark McGinnis said temperatures will climb into the low to mid 90s in the afternoon and it will feel like between 105-109 degrees. Some morning rain could delay the onset of the heat before temperatures soar in the afternoon.
